reactjs - 安装错误:- npm install -g create-react-app

Question

我正在 Udemy 上学习“Modern React with Redux Course”，有讲师要求先安装 NodeJs，然后安装“npm install -g create-react-app”，当我尝试运行此命令时，我得到了错误:-

npm install -g create-react-app
npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules
npm ERR! path /usr/local/lib/node_modules
npm ERR! code EACCES
npm ERR! errno -13
npm ERR! syscall access
npm ERR! Error: EACCES: permission denied, access '/usr/local/lib/node_modules'
npm ERR!  { [Error: EACCES: permission denied, access '/usr/local/lib/node_modules']
npm ERR!   stack:

npm ERR!   errno: -13,
npm ERR!   code: 'EACCES',
npm ERR!   syscall: 'access',
npm ERR!   path: '/usr/local/lib/node_modules' }
npm ERR! 
npm ERR! The operation was rejected by your operating system.
npm ERR! It is likely you do not have the permissions to access this file as the current user

npm ERR! the command again as root/Administrator (though this is not recommended).

npm ERR! A complete log of this run can be found in:
npm ERR!     /Users/nitintushir/.npm/_logs/2019-09-20T15_22_12_437Z-debug.log

然后我在 stackoverflow 上回答了一些问题，有人建议运行这个命令:-

 npm cache clean --force

我得到了:

npm WARN using --force I sure hope you know what you are doing.

然后我运行

npm install -g create-react-app

再次命令，但仍然出现相同的错误，有什么解决方案/建议吗？

它看起来像是访问权限错误，您应该尝试以 root 身份运行安装，如下所示:

sudo npm install -g create-react-app
