安装 npm install -g @angular/Cli 时出错

Question

D:\CDAC Project\Nodejs>npm install -g @angular/cli

我已经阅读了很多文章来解决这个错误以及你管视频，但它不起作用。

Answer 1

这是我找到的解决方案

解决方案：-

第 1 步：如果 angular/cli 已经安装，则卸载它

npm uninstall -g @angular/cli

第 2 步：尝试删除以下文件夹（如果仍然存在）

C:\Users\Akash Tawade\AppData\Roaming\npm\node_modules\@angular

第 3 步：尝试删除文件“ng”和“ng.cmd”（如果存在）。您将在以下文件夹中找到这些文件。

C:\Users\Akash Tawade\AppData\Roaming\npm\ng 

C:\Users\Akash Tawade\AppData\Roaming\npm\ng.cmd

第 4 步：再次全局安装 angular/cli

npm install -g @angular/cli

Answer 2

只需将以下标签添加到您的命令中：

npm install -g @angular/cli --unsafe-perm=true --allow-root
