I upgraded Angular CLI to v13 globally, and when I try to use ng command it gives me this error:

I saw here that Angular v13 is compatible with Node v16.10.x so I installed Node v16.10.0 and it does not work again.

I perform standard operations:

npm uninstall -g @angular/cli
npm install -g @angular/cli@latest

I even try to clear npm cache and it still didn't work.

When I downgrade it and install Angular CLI v12 globally, everything works again.

Is this some known Angular CLI v13 issue?

Environment:

Windows 10 (win32 x64)

Answer 1

我觉得你需要把ng.js文件编码格式bom+utf8改成utf8

Answer 2

On Windows .js files are associated to Windows Scripting Host by default, so the script will not be run with Node. You can open explorer and find a .js file, you can check that it's not considered JavaScript.

Open a JavaScript file's properties and in the associated programs (or open with), link the node.js exe file to open that kind of files.

1. Use the following command to delete your version

 npm uninstall -g @angular/cli

2. Unistall the node file with the following command

 npm uninstall

3. Go to your computer's file explorer Enter drive C. In the "search This PC" section, search for the word "App Data" and then "Roaming" Delete your "npm" file in the "Roaming" folder
4. Enter the "npm install" command again
5. Now it's time to enter the command "npm install -g @ angular / cli"

I am going to suggest you an alternative solution, which is the one I use to face the problems that gave me having only one version of node and having many different projects: TO USE A NODE MANAGER

I would recomend you Volta , a hassle-free way to manage your JavaScript command-line tool.

Just download its installable from here: https://github.com/volta-cli/volta/releases/download/v1.0.5/volta-1.0.5-windows-x86_64.msi and run it (with administrator permissions) to install it.

Once you have it installed, just run: volta install node@16 (or use another particular version of Node) It will install a new version of node, but "in a different way", although it will be transparent to you:

Volta does not use any fancy OS features or shell-specific hooks. It's built on the simple, proven approach of shims. Whenever you install a tool with Volta, it adds a shim to your PATH that acts as an intelligent (and fast) router to the right version of the tool and runs it with the right Node engine. Volta is easy to install, with no external dependencies, because it's built in Rust as a single, fast native executable.
