Error: Failed to install CocoaPods dependencies for iOS project, which is required by this template

I posted in detail what the bug is I got at SO.

I am getting this when trying to install React Native for MacOS.

$ npx react-native init myproject

My Mac version is Catalina 10.15.7 (19H2). XCode is version 12.

I tried everything from https://stackoverflow.com/questions/58934022/react-native-error-failed-to-install-cocoapods-dependencies-for-ios-project-w, but nothing worked. I invoked brew install cocoapods as well.

Any ideas how to get past this? Could it be something to do with the fact that I have a node_modules folder higher up in the directory structure (above where I am running the commands)? I don’t know what this error means.

Here is also output from the missing command:

$ /Users/lancepollard/Library/Caches/CocoaPods/Pods/Release/Flipper-Glog/0.3.6-1dfd6/missing --help
/Users/lancepollard/Library/Caches/CocoaPods/Pods/Release/Flipper-Glog/0.3.6-1dfd6/missing [OPTION]... PROGRAM [ARGUMENT]...

Handle `PROGRAM [ARGUMENT]...' for when PROGRAM is missing, or return an
error status if there is no known handling for PROGRAM.

Options:
  -h, --help      display this help and exit
  -v, --version   output version information and exit
  --run           try to run the given command, and emulate it if it fails

Supported PROGRAM values:
  aclocal      touch file `aclocal.m4'
  autoconf     touch file `configure'
  autoheader   touch file `config.h.in'
  autom4te     touch the output file, or create a stub one
  automake     touch all `Makefile.in' files
  bison        create `y.tab.[ch]', if possible, from existing .[ch]
  flex         create `lex.yy.c', if possible, from existing .c
  help2man     touch the output file
  lex          create `lex.yy.c', if possible, from existing .c
  makeinfo     touch the output file
  tar          try tar, gnutar, gtar, then tar without non-portable flags
  yacc         create `y.tab.[ch]', if possible, from existing .[ch]

brew install cocoapods

worked for me like a charm after try every possible solution, I have a M1 2020, hope it helps

@xjord not sure if you found it already but it was because of some compiler flags left in some random file, it’s in here in some thread somewhere I just don’t remember where! Some LLVM flags.

Thanks @lancejpollard, I was able to fix it with git config --global core.autocrlf false. I found out that git config core.autocrlf should be set to false otherwise git checkout will often try to turn LF line endings into CRLF, which can easily break fragile files.
