angular cli : ng commands shows Invalid character error

Remove this path in environment variables

C:\Users\{user}\AppData\Roaming\npm\node_modules\@angular\cli\bin

Then add this path to environment variables if you have not already

 C:\Users\{user}\AppData\Roaming\npm

For anyone else running into this same issue, I had to delete the system environment variable for the Angular CLI and then restart my console window.

C:\Users\{user}\AppData\Roaming\npm\node_modules\@angular\cli\bin

I came across the same error and wanted to share some insights on how I resolved it.

Error Details-

(my username)\AppData\Roaming\npm\node_modules@angular\cli\bin\ng.js Line: 1 Character: 1 Error: Invalid Character Code: 800A03F6 Source: Compilation error Microsoft Jscript

Probable Cause-

When you try to install @angular/cli globally, there seems to be an issue with the build in ng.js file.

npm install -g @angular/cli

Resolution-

Uninstall the globally installed angular/cli

npm uninstall -g @angular/cli

Clear npm Cache -

npm cache clean --force

Install @angular/cli locally and it seems to be working fine.

npm install @angular/cli

Also, after installation make sure you add the path to your environment variable

Example- "C:\Users{user_name}\node_modules.bin

It will be installed in the path where you'll run the installation for angular/cli

Remove the user environment variable

C:\Users\satsi\AppData\Roaming\npm\node_modules@angular\cli\bin
