Question: I met the fatal build error while integrate flipper, need help !!!

[OuterCloud]

I just follow the tutorial(https://fbflipper.com/docs/getting-started/ios-native/#cocoapods) and integrate flipper into my app, but I met the fatal error again and again, I try to compare the difference between my app and the flipper/iOS/Sample, I put my Podfile into flipper/iOS/Sample and it can build succesfully. Several days I could not solve this problem, hope to get help from author.

My app's github is: https://github.com/OuterCloud/ForFlipper

These are my steps:
First of all, create an iOS app project, then

1. Modify the Podfile
2. pod install
3. command+r/command+b

Below is what I got:
fatal error: module map file '/Users/tianyou.lan/Library/Developer/Xcode/DerivedData/ForFlipper-eqfmlwbvovnhmlbpnkauamydqxbt/Build/Products/Debug-iphonesimulator/YogaKit/YogaKit.modulemap' not found
