<p>以上所有解决方案都不对我有用。在Windows 7上，此方法有效：</p>
<p>安装快速环境编辑器并删除节点的所有条目，<code>npm, angular-cli or @angular/cli</code></p>
<p>卸载node.js并重新安装。再次运行Rapid Environment Editor，并确保node.js和npm位于系统或用户路径中。使用以下命令卸载任何现有的ng版本：</p>
<pre><code>npm uninstall -g angular-cli
npm uninstall -g @angular/cli
npm cache clean
</code></pre>
<p>删除<code>C:\Users\YOU\AppData\Roaming\npm\node_modules\@angular</code>文件夹。</p>
<p>重新启动，然后最后运行：</p>
<pre><code>npm install -g @angular/cli
</code></pre>
<p>然后屏住呼吸并运行ng -v。如果幸运的话，您会得到一些爱。每次运行ng命令时，请屏住呼吸，因为ng运行良好后，“找不到命令”已神奇地复现了几次，我认为问题已解决。</p>

<p>我尝试了以上所有方法，但仍然坚持在全球范围内发展。因此，我在powershell中运行<code>Get-Command ng</code>，然后很清楚我的问题是什么。过去，我大量使用纱线，所有旧的角度cli包也已全局安装在纱线存放位置。我已经删除了我的纱线缓存，这是一个很好的措施，但可能可以通过纱线更新全局角度cli。无论如何，我希望这可以帮助您提醒一些人，如果您使用yarn，那么ng等全局命令也可以位于npm放置它们的其他路径之外。</p>
