react-packager意外令牌(与流相关)

Question

这种情况时不时地发生在我身上。在缓存清理后，“突然”的原生反应停止工作，似乎没有明确的原因。

/Users/Shared/projects/project/node_modules/react-native/packager/react-packager/src/Logger/index.js:85
printFields? = [])
           ^
SyntaxError: Unexpected token ?

    at Object.require.extensions.(anonymous function) [as .js] (/Users/Shared/projects/project/node_modules/babel-register/lib/node.js:154:7)

我在react-native 0.38.0，node 6.1.0上，但也尝试切换到node 6.9.2，尝试删除和重新安装(通过yarn) node_modules文件夹。我相当确定具体的错误是不相关的。似乎正在发生的情况是流语法没有被识别。

.babelrc

{
  "presets": [
    "react-native",
    "react-native-stage-0",
    "react-native-stage-0/decorator-support",
  ]

}
