安装时出错：-npm安装-g创建反应应用程序

Question

我在Udemy上学习“现代React with Redux课程”，讲师要求先安装NodeJs，然后安装“npm安装-g创建React应用程序”，当我尝试运行此命令时，我遇到一个错误：-

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!    'Error: EACCES: permission denied, access \'/usr/local/lib/node_modules\'',
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! A complete log of this run can be found in:
npm ERR!     /Users/nitintushir/.npm/_logs/2019-09-20T15_22_12_437Z-debug.log

然后我讨论了有关stackoverflow的一些问题，其中有人建议运行以下命令：-

 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，但仍然得到相同的错误，任何解决方案/建议？

Answer 1

您应该使用nvm来管理节点和npm版本。https://github.com/nvm-sh/nvm

这将允许您在没有任何sudo权限的情况下全局安装节点模块

您还可以随时使用nvm CLI更改节点版本

Answer 2

它看起来像一个访问权限错误，你应该尝试运行你的安装作为root像：

sudo npm install -g create-react-app
