Question

这种情况不时发生在我身上。在缓存清理后，“突然”反应 - 本机停止工作而没有看似明确的原因。

printFields? = [])

我在react-native 0.38.0，节点6.1.0上，但也尝试切换到节点6.9.2 尝试删除并重新安装（通过纱线）node_modules文件夹。我很确定具体的错误是无关紧要的。似乎正在发生的是流语法未被识别。

.babelrc

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

}

有什么建议吗？

Answer 1

我在这里得到的最简单的答案是：降级到Node 5.x。

答案较长的原因可能是transform-flow-strip-types中的错误（未剥离?），但是通过包含{es2015-node的Babel预设来规避transform-es2015-parameters 1}}。但是，es2015-node仅在Node＆lt; = 5.x。

中运行时包含插件
