我正在尝试使用此命令安装 React 应用程序

Question

npm install -g create-react-app

然后我得到这样的错误：

npm ERR! code EPERM

npm ERR! syscall mkdir

npm ERR! path C:\Windows\system32\node_modules

npm ERR! errno -4048

npm ERR! Error: EPERM: operation not permitted, mkdir 'C:\Windows\system32\node_modules'

你的 npm install 是系统范围的，这意味着你必须 运行 你的 cmd/terminal as admin/root 才能在 npm install 上使用 -g 标志.您也可以将 node.js/npm 重新安装到您的用户目录中。
