【问题描述】：
我一直在尝试使用 react native 并创建一个项目，但未能做到。
我正在使用来自https://facebook.github.io/react-native/docs/getting-started.html的说明
Node 和 watchman 已经安装好了，然后当我进入时：
npm install -g react-native-cli
我明白了：
/usr/local/bin/react-native -> /usr/local/lib/node_modules/react-native-cli/index.js
react-native-cli@1.0.0 /usr/local/lib/node_modules/react-native-cli
├── semver@5.3.0
├── minimist@1.2.0
├── chalk@1.1.3 (ansi-styles@2.2.1, escape-string-regexp@1.0.5, supports-color@2.0.0, has-ansi@2.0.0, strip-ansi@3.0.1)
└── prompt@0.2.14 (revalidator@0.1.8, pkginfo@0.4.0, read@1.0.7, winston@0.8.3, utile@0.2.1)
当我尝试这样做时：
react-native init AwesomeProject
我明白了：
This will walk you through creating a new React Native project in /Users/jaimito/AwesomeProject

如何防止错误发生？
我正在使用 Mac。
我在命令的开头使用了 sudo。但是当我这样做时：
cd AwesomeProject
react-native run-ios
我明白了：
fs.js:640
return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
^

我一开始尝试使用 sudo，结果如下：
fs.js:640
return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
^
Error: EACCES: permission denied, open '/Users/jaimito/.babel.json'

【问题讨论】：
-
尝试：chmod 777 on "/Users/jaimito/.npm/optimist/0.6.1"
-
或尝试使用 sudo 运行命令
