Won't run on Linux (Debian based) about learnyounode HOT 18 CLOSED

Can you give any more information about this? Any error messages? Any problems installing? What exactly does it do, or not do and what version of Node are you using?

(learnyounode was mainly developed on Ubuntu btw and should work across all major platforms supporting Node).

from learnyounode.

Also, which terminal emulator you are using? (+ node version) Works for me in Mint 14

from learnyounode.

Hi guys,

I'm using node v0.10.18 on Mint 15, running the standard terminal. I followed the instruction here to install the more recent node as I was previously running a much older version:
https://github.com/joyent/node/wiki/Installing-Node.js-via-package-manager

Cheers,

can you give us a screenshot or something? perhaps let us know what echo $TERM gives you. Also make sure your terminal is large enough, it should be somewhere >= 80 chars wide to fit it on, although even if it's skinnier than that it'll just wrap and be ugly.

from learnyounode.

Works for me on node v0.10.18 on Mint 15 in standard gnome-terminal (xterm). A screenshot or other error information would help troubleshoot, @EwanValentine.

But as a shot in the dark, did you remember the -g in npm install -g learnyounode?

from learnyounode.

'echo $TERM' outputs 'xterm'

Yeah I used the -g flag, had to sudo it. I wish I could give more info but when I run the command 'learnyounode' it just moves down onto the next line. There must be a conflict of some description on my laptop

Cheers,

@EwanValentine Hmm, does it work if you do 'sudo learnyounode' ?

from learnyounode.

No luck! Does the same :S

from learnyounode.

and last resort, strace learnyounode :)

from learnyounode.

I'd do the following as well:

npm remove -g learnyounode
npm cache clean
npm install -g npm
npm install -g learnyounode

from learnyounode.

Ran that re-install, no luck.

Here's the strace results, prepare your eyes!

Judging by that, it does seem to be a folder or permission issue, I suspect?

I would advice against using sudo when installing node. Just causes more problems with permissions etc.

from learnyounode.

Does 'node -v' definitely show v0.10.18? I had an issue on Ubuntu yesterday and came to realise I was not running node from where I thought I was. I had to 'sudo apt-get remove node'.

from learnyounode.

I think you're probably right, I've just noticed something else quirky which makes me think it's probably actually my install of node. Node doesn't return anything, but nodejs does! node -v == 0 whereas nodejs returns the version number... I think I need to re-install node and try again.

As I think it's probably my node installation, I'll re-install and try again, I'll close the issue as it's my node. Cheers for all your help!

The default Ubuntu package installs as nodejs for some reason, I suspect
the Debian package is doing the same.

If you're running Ubuntu use Chris Lea's PPA. Otherwise it's pretty
painless to build from source.

Hi all..

Seems like I solved this issue..

Thanks to @sidorares..

The solution for @EwanValentine's issue is:

You need to remove 'node' application from your Linux [may be Debian]..

sudo apt-get remove node

As I think, terminal may be getting confused between node & nodejs..

Command learnyounode will work perfectly as it worked for me :P

Please do comment if any further issues.. :)

Cheers..
Happy Coding..

from learnyounode.

when you install learnyounode with
npm -g install learnyounode
it will list the installation directory as a path from your home directory just copy and paste the full install path into the command line and you should get learnyounode to run.
for example;
/home/yourusername/.node_modules_global/learnyounode
You can also add this to your $PATH environment variable then all you have to type is learnyounode at the command line
