react-native: MacOS: realpath not found

Description

The realpath command does not exist on MacOs.

Commit bb8ddd6c1247fde230a60c662a318422df52516e uses realpath instead of readlink.

Changing this in ./scripts/packager.sh resolved this issue for me (MacOs Montery, Silicon M1):

THIS_DIR=$(cd -P "$(dirname "$(readlink -f "${BASH_SOURCE[0]}" || echo "${BASH_SOURCE[0]}")")" && pwd)

where realpath is replaced by readlink -f

NOTE: readlink appears to be the more modern and more widely supported replacement for realpath

Version

brew install coreutils solves my issue. 🎉

I’m going to close this issue as brew install coreutils seems to be the valid answer.

I still have a couple of open questions:
1. Are you folks experiencing this in your own project or by cloning react-native?

2. Is this happening in a vanilla project or not?
We might need to either:
1. Update the docs to suggest `brew install coreutils` to everyone

2. Update the offending script to remove `realpath`.
I would need further context to understand what’s the follow up here.

This is not a good solution. This tool set has other tools, and it has the same name as the mac system’s built-in tools, which can cause more problems if you set environment variables. Fix the problem the right way, not with this flaky patch. ‘brew install coreutils’ After installation, environment variables need to be set PATH="/opt/homebrew/opt/coreutils/libexec/gnubin:$PATH Many commands have the same name. For example, ‘ln’ ‘mv’.

@cortinico It seems it is fixed in this commit: https://github.com/facebook/react-native/pull/34145 Apple removes stuff and break things. We need to use the latest version of React Native or brew install coreutils.

Just to re-iterate, this is fixed in 0.71 (at least for the packager.sh script).
