Error: EACCES: permission denied, open ‘/Users/leicunjie/.babel.json‘

at Error (native)

at Object.fs.openSync (fs.js:549:18)

at Object.fs.writeFileSync (fs.js:1156:15)

at save (/Users/leicunjie/HelloWorld/node_modules/react-native/node_modules/babel-register/lib/cache.js:57:40)

at nextTickCallbackWith0Args (node.js:420:9)

at process._tickCallback (node.js:349:13)

解决办法：改变.babel.json文件的访问权限

zhangxus-MacBook-Air:~ Brisy$  ls -al | grep .babel.json

-rw-r--r--    1 root   staff  9801451  9 17 10:26 .babel.json

zhangxus-MacBook-Air:~ Brisy$ sudo chown Brisy ~/.babel.json

Password:

zhangxus-MacBook-Air:~ Brisy$ ls -al | grep .babel.json

-rw-r--r--    1 Brisy  staff  9801451  9 17 10:26 .babel.json

然后重新react-native init 项目名称
