Question

我正在尝试安装create-react-app，但它引发了这个错误-

rem$ npm install -g create-react-app
Command failed: /bin/sh -c /usr/local/bin/node /usr/local/lib/node_modules/npm/bin/npm-cli.js config get cache --parseable
/usr/local/lib/node_modules/npm/bin/npm-cli.js:82
      let notifier = require('update-notifier')({pkg})

我同时更新了npm和node，但是仍然遇到相同的问题。

我在npm上遇到了类似的麻烦。尽管我有节点10，但它仍默认为node @ 4。然后我安装了nvm并使用它安装了特定的nodejs版本并使用了它。在Mac上，

nextProps.navigation.state.param.data

npm安装错误-SyntaxError：作用域声明
