尝试使用%AppData%\npm\设置系统变量路径。确保AppData文件夹的可见性。这个文件夹应该是可见的(而不是隐藏的)。

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

我也遵循这个问题，所以我尝试了这个命令，它工作得很好。 使用命令:npm run ng

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".

在尝试更新Windows 7 (x64)上的PATH变量之前，运行CMD控制台AS ADMINISTRATOR和ng命令对我有用，这也适用于VISUAL STUDIO CODE控制台。

它为我工作在CMD控制台/ VS CODE

这个方法几乎适用于我，但我必须使用:%USERPROFILE%\AppData\Roaming\npm ． 在环境变量中…/ /系统变量的路径

然后当我执行CMD: "ng -v"时，我得到了angular cli的正确响应。
