I suddenly get an error message when doing npm start about angular-gettingstarted HOT 9 CLOSED

Is it possible you are not in the appropriate directory when you execute the command? You need to be in the folder containing the package.json file.

Sorry for note getting back to you before now, but I didn't have the chance to check it before now.

I can't believe that I hadn't seen tat error on top of all the red ERR's.

Everything works just fine now. Thank you very much!

from angular-gettingstarted.

I'm starting it from the same folder that I've always started it from. And package.json is in that folder.

I downloaded all the files from your github again, and installed it on another directory on my computer. I did npm install and the npm start. Everything worked just fine. So something must have happened to my old installation.

I did a test:

I slowly copied files from the old installation where I've added and changed files while following the course module (the installation that doesn't work anymore) over to the new one. After copying each file I did npm start again. When I had copied over the file called product.service.js, the error also started to appear in the new installation. I've no idea why. It could be a coincidence of course.

Seems like I just have to start all over again. Or use the FINAL-folder for the rest of the course. If you don't have any other suggestions

When you ran npm start ... if you look after the command in the console, are there any errors listed before the info you posted above? Some syntax errors will prevent it from starting.

Also, the service should be product.service.ts, not .js

from angular-gettingstarted.

There's both a .ts and a .js file called product.service.

Here's the complete output when writing npm start:

from angular-gettingstarted.

Ah! You have 3 syntax errors. They are shown immediately above the first npm error line. It even gives you the line number and character in that line that is causing the errors.

from angular-gettingstarted.

Were you able to resolve your syntax errors? Can we close this?

I have no idea how to continue

from angular-gettingstarted.

Please ensure you have downloaded the current code from this github folder. The error message you are seeing above is from a very old version of the code.

if you look in the package.json file, you should see this:

  "scripts": {
    "ng": "ng",
    "start": "ng serve -o",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e"
  },

And not this:
tsc && concurrently "tsc -w" "lite-server"

That has not been in the code for almost 2 years.

There are numerous copies of my code in other repositories on github that other developers have copied and not kept up to date.

Let me know if that resolves your issue.
