我正在尝试安装 nvm 并卸载了 nvm。只有在此之后，我才收到此错误。

谁能帮我在这里做错了什么？

谢谢

我已经遇到并解决了这个与 node-sass 和 python 错误相关的问题。尝试按照以下步骤安装最新的 angular cli 命令

同时设置系统变量路径：

C:\Users\windowsusername\AppData\Roaming\npm

C:\Users\windowsusername\AppData\Roaming\npm\node_modules\@angular\cli\bin;

C:\Program Files\nodejs;

然后开始使用 angular cli 命令提示符：

angular 客户端项目文件夹路径>npm install -g @angular/cli@latest

angular 客户端项目文件夹路径>npm install -g node-gyp
