問題
不過大部分用戶可能會遇到什么react-deep-force-update的.babelrc的一個(gè)unkonw option充边，那是因?yàn)橐蕾嚨牡谌桨?react-proxy, 目前 master 已經(jīng)修復(fù)了)還在使用老版本的Babel，所以你可以參考如下的方案
https://github.com/facebook/react-native/issues/5393
即在 package.json 的 scripts中增加如下選項(xiàng)：
"scripts": {
"clean:babelrc": "find ./node_modules -name react-packager -prune -o -name '.babelrc' -print | xargs rm -f",
"postinstall": "npm run clean:babelrc"
}
然后就能正在執(zhí)行了贡避。
