I tryied to run the installer on my mac and I get the following error:

Seems that the url changed:

curl: (22) The requested URL returned error: 404 Not Found

I just tried updating from 0.35 to 0.38 using the script. This is what happens in the terminal:

$ which deno

That EOF or read error happens immediately; it doesn't seem like there's a chance for me to do anything.

Solved by removing the existing deno binary first.

I guess npm would be the most familiar way for Node developers to install Deno.

So how about a simple postinstall script in the package.json so you can run npm install deno to install Deno into $HOME/.deno/bin?

npmjs.com/deno is already taken by a "Bridge to deno" package that only has a README so far, but we could ask the author of that package to transfer ownership.

The TypeScript declaration files could be published in the package, too.

If we did that, editors that don't know about Deno, but that do understand TypeScript and auto-download declaration files for code-completion from npm (for example, VS Code), would make it very convenient to get started: You would just have to create a my-script.ts file, open it in your editor, type import * as deno from 'deno', and the editor would give you auto-complete, so you could type deno.en, hit tab, deno.env() would be auto-completed, and you could hover over deno.env() with your mouse to read the docs ... That would be very convenient. :)

The install script makes the assumption that unzip is available. It is not available by default in WSL and probably other environments. Ideally the script would check for this before downloading deno.

It would then prompt the user to install unzip with apt and exit.

Could you please support windows 32 bit machines for the build.

I'm using Windows NT 10 15063

Building the app is quite a sassle for me (as win32 users) because:

• My windows version does not support symlinks even though I enabled developer options.
  
• Installing MSVC is quite a sassle (I tried 5 times; the download can't finish)

By the way, I have very limited resources; RAM, CPU even Storage
Needed requirements

• Updated Windows version with Dev Options enabled (.symlinks not working for me)
• Cargo or Rust in general (not installable for me since it needs MSVC)
• MSVC (not installable for me)
• Python version 2, not 3 (working for me)

I think anyone with the listed above resources .
can build it NOW and send it because I think it is not a difficult task and
I'm not even trying to go into node and I NEED it desperately. PLEASE HELP.

Hi, first of all, thank you for this awesome project to Ryan and all contributors. You rocks guys!

Now that Deno has been reached a stable status, I think is time to make a new web (like Node is working on).

I'm not so good as designer but I can support as developer. So, maybe there is a UI/UX guy that could help with the design. It would be great.

What do you think?

PD: Sorry for open the issue in this repo. I didn't realize that is not the main one.

I'm on Windows (using git bash) so this doesn't work

I can alter the command so the reference is correct but it turns out the curl install just isn't formatted for windows:
'/c/Users/John Vandivier/.local/bin/deno' --help -> Exec format err

If the intent is windows users shouldn't install via curl and must use chocolatey, plz clarify that on the website which currently implies that either would work:
https://deno.land/

The following issue shows up when trying to install on Windows 10.

iwr : The request was aborted: Could not create SSL/TLS secure channel.
At line:1 char:6
+ iex (iwr https://deno.land/x/install/install.ps1)

You need to do first do the following command in your powershell.

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

This command is present on line 7 of the install.ps1 script, but the script errors out before it reaches this line. Because this needs to be set to establish a connection and when you try to connect to "set the command", you already run into the Tls11 issue.

Maybe its better to update the documentation? Or have a batch file that the user download, where this command is set first, before the iex command is run.

I'm very much a noob when it comes to internet protocol stuff, and I was just trying to install Deno on a server that only has an IPv6 address:

$ curl -fsSL https://deno.land/x/install/install.sh | sh
curl: (7) Failed to connect to deno.land port 443: Connection timed out

Is this expected behavior?

Whenever I try to run

curl -L https://deno.land/x/install/install.py | python

I get the following along with the executable not appearing under ~/.deno/bin/

I am on a Mac running version 10.14.1

Since denoland/deno@e782ba1 deno now stores cache files in platform dependent cache directories like $HOME/Library/Caches (mac).

Downloading the deno binary into $HOME/.deno/bin seems now inappropriate.

Where should it be installed?

cc @flying-sheep

Now that we have a shell one, which has fewer deps than the python, and now that all the documentation has been updated to point at install.sh, we should remove the python installer.

I ran the installer on my computer, got this:

pi@raspberrypi:~ $ deno --help
bash: /home/pi/.deno/bin/deno: cannot execute binary file: Exec format error

• Re-add testing the sh installer on osx
• Re-add testing the sh installer with different shells (ksh, zsh, dash, bash, and sh)
• Once the pwsh installer is cross-platform, add win, osx and linux tests
• Once the sh installer is cross-platform, add win test

System: Ubuntu 18.04
Deno Version: v0.10.0 / 2019.06.25

tried to install deno from my home dir (it has a folder "sh" in it), so:

(23) Failed writing body
(pwd now: ~/sh)

does it have smth to do with /bin/sh ?
(re)installing from another folder works normally

The Deno website mentions the following installation option:
Using Homebrew (macOS or Linux):

But when I try to install it using brew install deno I see the following error message:

deno: macOS is required.
Error: An unsatisfied requirement failed this build.

Is the website outdated or should this work? 😄

see:
https://deno.land/x/install/install.ps1#L54
https://deno.land/x/install/install.ps1#L58
https://deno.land/x/install/install.ps1#L70

vs
https://github.com/denoland/deno_install/blob/master/install.ps1#L54-L70

this messes up highlighting for the rest of the file, making it harder to read than a plain text

I'm on a Win10 machine and I followed the Powershell installation step. The error message said "the IE engine is not available". I confirmed that I do have IE installed on the machine.
How can I check and fix this?

Since there's already a Python, a PowerShell, soon a Deno, and perhaps a Bash install script, we might want to:

1. standardize the steps that are to be executed on each platform (osx, linux, win32)
2. standardize the log messages that will be printed
3. refactor the scripts and tests accordingly

This might be related to this stackoverflow question.

This is the error message I've got from CI. Something went wrong with the server.

$ #!/bin/bash -eo pipefail
curl -fsSL https://deno.land/x/install/install.sh | sh

curl: (22) The requested URL returned error: 503 Service Unavailable

asdf is a popular tool that helps a bit with the management of the languages (which brew doesn't give us a good solution for it, at least in MacOS)

Would be nice to have an asdf plugin for managing Deno

I just tried running the shell command from the README:

curl -fsSL https://deno.land/x/install/install.sh | sh

And go the error:

curl: (6) Could not resolve host: deno.land

Any clues as to what I am doing wrong?

Install deno via apt on Debian/Ubuntu

repro steps and resulting error

1. open new PowerShell session as admin on Windows 10 (I do have ConEmu installed as a console wrapper)
2. run iwr https://deno.land/x/install/install.ps1 -useb | iex as instructed on Deno website
3. receive below error (text and image both presented)

Error text: "iex : Cannot validate argument on parameter 'Uri'. The argument is null or empty. Provide an argument that is not null or empty, and then try the command again."

other info

cmd --version results with Version 10.0.18362.720

In would be reasonable to give users the opportunity to easily install deno on macOs using brew formula.

Since there's a .sh installer now, might be worth it to make it work on the Linux subsystem for Windows, too.

Perhaps even MinGW and similar.

Not quite sure which CI options there are to ensure this is properly tested.

See https://github.com/denoland/deno/blob/v0.37.1/.github/workflows/ci.yml#L196-L204

We're using LLVM target triples in the filenames now.

To fix broken builds.

I need to run commands in deno without saving them in file, so I use piping. Even though it has few weird things (such as returning undefined at the end), it works well. The only thing is when I try to import module, it doesn't work. Is there a way to fix that?

EG curl -sSf https://raw.githubusercontent.com/denoland/deno_install/master/install.py v0.1.12 | python

Since both curl and python aren't pre-installed on Windows, curl -sSf https://raw.githubusercontent.com/denoland/deno_install/master/install.py | python is not a very convenient way to install deno.

Creating a proper .msi or .exe installer is probably too much work at the moment. However, adding deno to a Windows package manager is fairly easy.

As far as I know, there are two major package managers for Windows: Chocolatey and Scoop.

Since scoop is more actively maintained than choco, arguably easier to use, and focused on developer tools, I decided to make a PR for adding deno to scoop. Since it has already been merged, deno can be installed with scoop install deno on Windows.

I think in future, there should be multiple options for users to install deno on Windows:

• Download deno.exe file
• Download deno.zip file
• Download deno-setup.exe file
• Install from powershell.exe: iex (iwr https://raw.githubusercontent.com/denoland/deno_install/master/install.ps1) (see: denoland/deno_install/#4)
• Install from pwsh.exe: iex (iwr https://raw.githubusercontent.com/denoland/deno_install/master/install.ps1)
• Install via Scoop: scoop install deno (see: lukesampson/scoop/#2570)
• Install via Chocolatey: choco install deno
• Install via npm: npm install deno

https://deno.land/x/install/install.ps1 redirects to https://raw.githubusercontent.com/denoland/deno_install/master/install.ps1:

$ curl -I https://deno.land/x/install/install.ps1 | grep Location:
Location: https://raw.githubusercontent.com/denoland/deno_install/master/install.ps1

deno.land does not work with TLS 1.0.

$ curl --tls-max 1.2 https://deno.land/x/install/install.ps1
$ curl --tls-max 1.0 https://deno.land/x/install/install.ps1
-curl: (35) error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure

However, raw.githubusercontent.com works fine with TLS 1.0.

$ curl --tls-max 1.2 https://raw.githubusercontent.com/denoland/deno_install/master/install.ps1
$ curl --tls-max 1.0 https://raw.githubusercontent.com/denoland/deno_install/master/install.ps1

There have been a number of issues because PowerShell <v6 uses TLS 1.0 by default.

For example:

• #51
• #16
• denoland/deno#1729

The default PowerShell version for Windows 8 is v4, for Windows 10 it is v5. So this impacts nearly all PowerShell users.

The following fixes are possible:

• (1) Changing the one-line install command to use TLS 1.2

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12; iwr https://deno.land/x/install/install.ps1 | iex

• (2) Changing the one-line install command to point directly to GitHub

iwr https://raw.githubusercontent.com/denoland/deno_install/master/install.ps1 | iex

• (3) Enabling TLS 1.0 for deno.land

If you have a prior version of Deno installed, it would be cool to upgrade using this:

> deno https://deno.land/x/install/install.ts 

https://chocolatey.org

Hello! Thanks for an interesting project.

When I try to install Deno as the main website tells me, I get an error:

iex doesn't work with param. See https://ci.appveyor.com/project/MarkTiedemann/win-ci-playground/builds/21844216.

So apparently this installation method hasn't worked since #22.

This is easy to fix, luckily:

if ($args.Count -gt 0) {
  $Version = $args.Get(0)
}

I already tested it, and it works: https://ci.appveyor.com/project/MarkTiedemann/win-ci-playground/builds/21844766.

Will make a PR for it tomorrow and also add proper end-to-end tests for that.
