ng ：术语“ng”未被识别为 cmdlet 的名称，函数 Visual Studio Code Terminal

Question

在 VS Code 中运行命令ng build时出现错误

PS D:\Dashboard\Test1> ng build
ng : The term 'ng' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if   
a path was included, verify that the path is correct and try again.
At line:1 char:1
+ ng build
+ ~~
    + CategoryInfo          : ObjectNotFound: (ng:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

我已经添加了这些环境变量 Path

%USERPROFILE%\AppData\Local\Microsoft\WindowsApps;
C:\Users\Avind\AppData\Local\Programs\Microsoft VS Code\bin;
C:\Users\Avind\AppData\Roaming\npm;

我怎样才能摆脱这个问题？

注意：我node.js在C:\Program Files\nodejs. 从命令提示符ng new project不工作，但从node.js命令工作。

编辑 1：npm install -g @angular/cli@latest从 VS Code 终端执行后低于 msg 和ngcmd 不起作用

PS D:\Path\Test1> npm install -g @angular/cli@latest
npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142
C:\Users\Avind\AppData\Roaming\npm\ng -> C:\Users\Avind\AppData\Roaming\npm\node_modules\@angular\cli\bin\ng

> @angular/cli@9.1.9 postinstall C:\Users\AR20095474\AppData\Roaming\npm\node_modules\@angular\cli
> node ./bin/postinstall/script.js

Answer 1

您需要安装最新的 angular cli 才能使 ng 命令工作，您可以从命令终端或 Visual Studio 代码终端运行它

npm install -g @angular/cli@latest

如果仍无法正常工作，请卸载并重新安装node.js的program and feature。

Answer 2

如此处的Angular CLI所示，请确保您安装了 Angular CLI。
\n您可以从系统上的任何位置运行此命令。

npm install -g @angular/cli\nng --version\n

\n

它应该打印如下内容：

\n

Answer 3

这对我有用。尝试以前的答案对我来说不起作用。

运行这个命令

Set-ExecutionPolicy RemoteSigned -Scope CurrentUser

参考：

ng ：无法加载文件 \AppData\Roaming\npm\ng.ps1。文件 npm\ng.ps1 未经过数字签名 运行命令时出现 Angular 错误
