Question

我正在Udemy上进行“ Modern React with Redux Course”课程，那里的讲师要求先安装NodeJs，然后再安装“ 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 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上遇到了一些问题，有人建议运行此命令：-

 npm cache clean --force

我得到的

：

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，是否有解决方案/建议？

Answer 1

您应该使用nvm来管理您的节点和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

它看起来像是访问权限错误，您应该尝试以root身份运行安装：

        if #available(iOS 13.0, *) {
            let apperiance = UINavigationBarAppearance()
            apperiance.configureWithOpaqueBackground()
            self.navigationController?.navigationBar.scrollEdgeAppearance = apperiance
        }

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