设置路径= % %路径;C: \ \ \ AppData \ \ npm漫游用户

对我来说，PATH环境变量有问题。我删除了所有与npm相关的路径，并在path的开头添加了这个文件夹:

c:\Users\<your-user-name>\AppData\Roaming\npm\

确保你有;之间的路径。

打开cmd，输入npm install -g @angular/cli 在环境变量中，在用户变量或系统变量中添加“Path”value=C:\Users\your-user\.npm-packages\node_modules\.bin 打开cmd: c:\>cd your-new-project-path .．.\project-path\> ng new my-app 或者ng all-ng-commands

我在Windows 7上也遇到了同样的问题，64位运行npm v3.10.8。

我按照建议添加了路径:(C:\Users.....(你的用户名)\AppData\Roaming\npm\node_modules\angular-cli\bin\ng)和卸载angular-cli。 在这之后，我清除npm缓存通过npm缓存清理提示这里https://blogs.msdn.microsoft.com/matt-harrington/2012/02/23/how-to-fix-node-js-npm-permission-problems/。这保证了没有剩菜。 用npm install -g angular-cli重新安装angular-cli，瞧。 希望对大家有用!

在我的情况下，我做了以下步骤。

所有程序-> Node JS->右键单击Node. JS命令提示符，选择属性和从目标字符串在结束复制下面

/k "C:\Program Files\nodejs\nodevars.bat"

我启动Visual Studio Code并打开下面的文件

C:\Users\gochinta\AppData\Roaming\Code\User\settings.Json，并给出如下

// Place your settings in this file to overwrite the default settings
{
  "terminal.integrated.shellArgs.windows": 
  ["/k", "C:\\Program Files\\nodejs\\nodevars.bat"]

}

现在我在Visual Studio Code终端窗口中输入ng -v，它工作了。

I was having the same issue when tried with the syntax "ng new " and solved that simply by updating the existing node version from 5.x.x to 8.x.x. After successful updation of node, the syntax worked perfectly for me. Please update the existing version of node. As it is clearly mentioned in angular documentation that these commands require the node version >= 6.9.x. For reference please check https://angular.io/guide/quickstart. It clearly states "Verify that you are running at least node 6.9.x and npm 3.x.x by running node -v and npm -v in a terminal/console window. Older versions produce errors, but newer versions are fine".
