d: warning: directory not found for option '-L/Users/whpc/Library/Developer/Xcode/DerivedData/InstallationPlatform-emxgvbriadwmiscbajbvqtdytnps/Build/Products/Debug-iphonesimulator/React'
ld: library not found for -lstdc++.6.0.9
clang: error: linker command failed with exit code 1 (use -v to see invocation)
原因：Xcode10取消了6.0.9的支持
最后贴一个最简单的办法，下一个lstdc++.6.0.9然后导入进去

真机运行库
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/lib模拟器运行库
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/lib
然后重新编译
运行之后又报这个：
