Angular JS installation Error thorough the 8 steps

[mozes2019]

@mozes2019

Here are the 8 steps of recent Angular JS class(21rst July 2025) as listed below :

1. npm install -g @angular/cli@16

2.  ng version
   

3. ng new helloworld
4. npm run start
5. npm install bootstrap
6. npm install bootstrap-icons
7. npm install bootstrap @popperjs/core
8. ng generate component home

I have on my actual pc, installed Windows 11 Pro Copilot built-in version and VSCode version June 2025(1.102)
I can run all Jupiter notebook, JS, etc.. code in my VSCode usually but Here is state the error message when I tried running the 8 steps above to get access to the HelloWord Angular JS code starting by 1rst step on the VSCode command line prompt :

npm install -g @angular/cli@16

npm : File C:\Program Files\nodejs\npm.ps1 cannot be loaded. The file C:\Program Files\nodejs\npm.ps1 is not
digitally signed. You cannot run this script on the current system. For more information about running

At line:1 char:1

• npm install -g @angular/cli@16

•   + CategoryInfo          : SecurityError: (:) [], PSSecurityException
    + FullyQualifiedErrorId : UnauthorizedAccess
  

---

And once I run three of your Github JSON codes (extensions.JSON, launch.JSON, tasks.JSON) for Angular JS test case, I got "Code language not supported or defined" error at right lower angle of VSCode window.
I got same error message for all other steps (2 thru 7)
The 3 screenshots here attached are stating the problem.

Need assistance and Guidance for security pre-requirements

Hey. Thank you for all the detailed info. Here is what I would suggest

Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass

This will help you bypass this error :)

You can also try this

Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned

Right now, due to some security polices on your laptop, scripts cannot run. So, this will help you bypass them.

Let me know how it goes, and feel free to let me know if you have more errors.

I don't know how to fix this error you have on your computer. I have not seen the type of errors you are seeing in my laptop or any of my students laptops in the past.

You can see in the red color warning, that your laptop has some "over ride" policy which is overriding this new policy. This is very strange.

Here are some things you try.

1. You are running this command in the terminal of VS Code. Instead of that use the "cmd" from the windows main search bar which will give you the command line
2. If you are getting the same error in your command line, then, next, try these commands in a new user account on your PC
3. If you are still getting the same error, you may have to reinstall the windows installation on your computer
4. Even after reinstalling the windows, if you are still getting the same error, then, you should try the commands on another computer

Please let me know which of these steps you tried, so I can give you the next step.

Thank you

I tried the first step resolution as stated below by executing the npm client 16 installation on windows cmd :

1. You are running this command in the terminal of VS Code. Instead of that use the "cmd" from the windows main search bar which will give you the command line

And found message in screenshot attached, please to confirm that is normal or not message before I continue on next 7 steps JS angular helloworld project installation (ng version, ng new helloworld, npm run start, etc.....)

All my best to you

@mozes2019
I got also this screenshot with command (ng version) ran on windows cmd prompt:

IS IT CORRECT BEFORE CONTINUE ON NEXT COMMAND (ng new helloworld) ?

All the best to you

Cece

[mozes2019]

@mozes2019
Should I say Yes or Not to the question when running the 3rd Angular JS HelloWorld command(ng new helloworld) as is captured here from Windows cmd ?

Wait for your feedback

Cece

@mozes2019

All the best

So, here, so far, it is looking good. The key step is,

You have to open the project folder you created in VS Code. Inside VS Code, you have to open terminal, you have to try the command, npm run start :)

Again, you are on the right track. You an also check the recording of the session.

Good week-end begining Mr JAY.
As we got JS Angular class this Friday 26th Sept, 2025, I would like just to report on my JS Angular installation issues that were successfully ran on Windows CLI and my VSCode terminal as you can see on a bunch of following attachments by category of commands :
1rst/ Download all 6 project folders from your Github into Videos sub folder(AIU_JSANG_API)

2nd/ 1rst JS Angular installation Command(npm install -g @angular/cli@16) and 2nd Command (ng version) were ran on Windows as you can see on following screenshots :


3rd/ Run the 3rd Command (ng new helloworldcece) in VS Code terminal to create new project (helloworldcece) as the 7th project in your Github default folder(AngularForStudents-main) in Videos folder after unzipping and under my customized folder (AIU_JSANG_API) as shown on following screenshots :



4th/The other 5 commands (4th to 8th) in VS Code Terminal as shown on following pdf attachment :
Other 5 JS Angular commands executed successfully as on 09262025.pdf

My question is now how to run each of your GitHub 6 projects, write my JS Angular project (helloworldcece) code, run it and access each of their Front End(EF) ?

Cece

@mozes2019

Just like you ran the existing project, you can open each project in a separate VS Code window.

Remember what I say in the class

"open VS Code window for every project folder you want to run"

Let me know if you have more questions.

Thanks
