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

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'
