我用谷歌搜索了错误，没有运气.我删除了 .babel.json，错误 stiil 出来了.我重新启动了一个新项目，还是一样.我卸载了 node.js 和 python，然后按照 RN 主页上的入门"再次安装它们，仍然相同.我安装了 react-native-cli 2.0.1 和 1.3.0，还是一样.

I google the error, no luck. I delete the .babel.json, the error stiil comes out. I reinit a new project, still the same. I uninstall node.js and python, then install them again follow the "Getting Started" on RN mainpage, still the same. I install react-native-cli 2.0.1 and 1.3.0, still the same.

看起来 RN 项目即使出现错误也能正常工作.但是你永远不知道这个错误什么时候会伤害到我的项目.

It seems the RN project works even with the error. But you never know when the error will hurt my project.
