发现自己新建的项目里node_modules文件夹好像少了很多东西？

This warning is caused by a @providesModule declaration with the same name across two different files.
jest-haste-map: @providesModule naming collision:
Duplicate module name: private
Paths: D:\work\RN-project\MyProject\node_modules\react-native\node_modules\jstransform\node_modules\commoner\node_modules\private\package.json collides with D:\work\RN-project\MyProject\node_modules\react-native\node_modul
es\babel-core\node_modules\private\package.json

来人啊

我也是这问题，才学，坐等大神

ject和babel-core的文件冲突了，新的rn版本么，我还在用旧的rn，所以没见过这个问题。看起来找找配置应该能解决，或者删掉ject，我估计你用不到自动化测试。
