$ react-native init NewProject

3.重装 node 包

$ yarn

4.运行项目

$ react-native run-ios

注意：我当时 run-ios 的时候报错

Loading dependency graph, done.
error: bundling failed: Error: Couldn't find preset "module:metro-react-native-babel-preset" relative to directory "/Users/xxxx/Documents/workspace/xxxx/NewProject"

fix：把根目录的 .babelrc 文件原来的内容:

{
  "presets": ["module:metro-react-native-babel-preset"]
}

改成:

{
  "presets": ["react-native"]
}

重新执行

$ react-native run-ios

运行成功
