Windows 上的 npm update -g 失败

Question

我在这里扯头发。当我从非提升的命令提示符运行 npm update -g 时，我得到这个：

npm ERR! code EPERM
npm ERR! syscall mkdir
npm ERR! path C:\Program Files\nodejs\node_modules\.staging
npm ERR! errno -4048
npm ERR! Error: EPERM: operation not permitted, mkdir 'C:\Program Files\nodejs\node_modules\.staging'

它为什么要在C:\Program Files\nodejs\node_modules\ 下创建一个.staging 目录？？它应该在C:\Users\[MY_USERNAME]\AppData\Roaming\npm\node_modules 下创建它。那是我的模块安装的地方。我不需要以管理员身份运行命令。

编辑：好的，我以管理员身份运行了命令，即使它没有任何意义，你猜怎么着？它仍然拒绝这样做！

npm ERR! code EEXIST

看起来它正在尝试更新 npm 本身。我删除 npm.cmd 并...

'npm' is not recognized as an internal or external command, operable program or batch file.

哦，对了！我多么愚蠢！好吧，现在我没有 npm 命令，必须重新安装 Node.js。

更新：修复安装了 NodeJS，然后返回管理员命令提示符并...

npm ERR! code EEXIST
npm ERR! path C:\Program Files\nodejs\npm.cmd
npm ERR! Refusing to delete C:\Program Files\nodejs\npm.cmd: is outside C:\Program Files\nodejs\node_modules\npm and not a link

究竟是什么……？！没有人能回答这个问题吗？！我应该完全擦除我的 Node 安装吗？？

Answer 1

EPERM：不允许操作 => 您的用户无法创建文件夹

解决方案：

1- 以管理员身份打开 cmd（右键单击选项 cmd）
