MacOS: realpath not found #34146

squio · 2022-07-06T18:36:12Z

Description

The realpath command does not exist on MacOs.

Commit bb8ddd6 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

Sorry but that is patching the problem by installing a backward compatibility shim for pre-2000 state

While this commit bb8ddd6 explicitly removes the current cross-platform command. Just why?

biallo · 2022-08-01T21:40:33Z

While this commit bb8ddd6 explicitly removes the current cross-platform command. Just why?

To provide context here: readlink didn't work with the new build setup we have internally. Every occurrence of readlink was replaced with realpath with a search-n-replace inside bb8ddd6

If you list the usages that needs to be reverted back, we can address them 👍

Same on MacOS 12.6, node v12.16.3, react-native 0.70.1

Quick heads up that node 12 is not supported by React Native. Min version is 14.
Also @zheoreh, are you invoking ./scripts/packager.sh directly or using another command?

zheoreh · 2022-10-04T07:49:58Z

@cortinico I just run react-native run-android && (npm run adb || true) && npm run log-android and it automatically open a new terminal and starts metro. In some way I was able to get node version within that terminal and it was node 12 but I use nvm and default version of node is v16.15.0. I don't know why it uses /usr/local/bin/node instead of /Users/mac/.nvm/versions/node/v16.15.0/bin/node.

% node -v
v16.15.0
% which node            
/Users/mac/.nvm/versions/node/v16.15.0/bin/node

If I start metro myself then everything is ok.

cortinico · 2022-10-04T10:39:16Z

I'm more concerned that you see ./scripts/packager.sh in your stacktrace:

/Users/mac/Documents/Projects/puertomap/node_modules/react-native/scripts/packager.sh: line 8: realpath: command not found

Which is a script that is internal to React Native and you should not be calling. I'm wondering why it's there.

Mr-Rith · 2022-10-17T04:33:58Z

same😭😭

cortinico · 2022-10-17T11:08:35Z

Can someone please clarify if:

You're experiencing this in your own project or by cloning react-native?
brew install coreutils solves your issue or not?

deftcat · 2022-10-19T04:25:04Z

brew install coreutils solves my issue. 🎉

cortinico · 2022-10-19T17:59:46Z

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:

Are you folks experiencing this in your own project or by cloning react-native?
Is this happening in a vanilla project or not?

We might need to either:

Update the docs to suggest brew install coreutils to everyone
Update the offending script to remove realpath.

I would need further context to understand what's the follow up here.

anaclette · 2022-10-19T20:02:28Z

brew install coreutils worked for me too, but right after having cleaned and rebuilt my project from xcode xcworkspace. To answer @cortinico's question, in my case I was experiencing this issue in a react native project of my own.

shrekuu · 2022-10-20T14:42:02Z

@cortinico It seems it is fixed in this commit: #34145
Apple removes stuff and break things. We need to use the latest version of React Native or brew install coreutils.

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'.

AsteriskZuo · 2022-11-06T01:27:44Z

I suggest using the command realpath -> readlink -f instead. It's much more reliable than installing a bunch of commands.

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

ariccio · 2022-11-24T23:23:15Z

Just bumped into this in an expo bare project. Hmph.

cortinico · 2022-11-25T12:10:48Z

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

For anyone struggling with this, I found out that the realpath: command not found might not be the root cause of your Metro not being able to start. The reason it's not starting is probably because you have multiple installations of npm/yarn, as mentioned in this issue. Following the steps from that same comment to uninstall and reinstall them resolved my problem. (I still see the realpath: command not found when running react-native run-ios, but Metro startup no longer breaks, and works normally)
