react-native开始报告：错误：未知：错误未知，打开... \。babel.json

Question

我在Windows 7上有一个RN开发环境。它运行良好，直到昨天它在我运行“ react-native”启动后突然报告错误。错误信息：

[2016-12-26 09:58:17]         HMR Server listening on /hot

React packager ready.

fs.js:557
  return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
                 ^

我用谷歌搜索错误，没有运气。我删除了.babel.json，出现了错误提示。我重新启动一个新项目，仍然一样。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，仍然相同。

看起来RN项目即使有错误也可以正常工作。但是您永远都不知道错误何时会损害我的项目。

Answer 1

我的node.js版本是7.5.0。

我昨天更新到7.10.0，问题解决了。
