Using postUpgradeTasks to run pod-install to update ios/Podfile.lock in bare React Native project

[jzaefferer]

How are you running Renovate?

Self-hosted

If you're self-hosting Renovate, tell us what version of Renovate you run.

37.27.1

If you're self-hosting Renovate, select which platform you are using.

GitLab self-hosted

Was this something which used to work for you, and then stopped?

I never saw this working

Wanted end result.

Very similar to #10335 I want to run pod install after updating dependencies, to update ios/Podfile.lock.

What you tried so far.

With the input from #25612, I've now got this script in my package.json:

"renovate:pod-install": "RUBY_VERSION=2.7.8 install-tool ruby && COCOAPODS_VERSION=1.14.2 install-gem cocoapods && yarn --ignore-scripts && cd ios && pod install",

I'm hoping to remove the ruby and cocoapods install, since that should already be available. Is it just not in the global PATH and I need to invoke a specific path?

I also created this renovate-config.js:

module.exports = {
  // this can only be used in a 'global' config: https://docs.renovatebot.com/getting-started/running/#global-config
  allowedPostUpgradeCommands: ['yarn renovate:pod-install'],
  baseBranches: ['renovate-updates'],
};

I'm using the baseBranches while debugging.

In my renovate.json itself very little changed:

"postUpgradeTasks": {
    "commands": ["yarn renovate:pod-install"],
    "fileFilters": ["ios/Podfile.lock"],
    "executionMode": "branch"
  },

Now the script runs, but eventually fails, because no node_modules are actually installed. Eventually it outputs this:

Error: Cannot find module 'expo/package.json'

 #  -------------------------------------------
 >  require File.join(File.dirname(`node --print \"require.resolve('expo/package.json')\"`), \"scripts/autolinking\")

(I stitched this together from stdout and stderror from the debug ndjson file; which I'm trying to parse with a script, but somehow node can't decode it correctly)

I seems like I'm pretty close, but since I don't really understand how renovate executes postUpgradeTasks, I'm stumbling around in the dark. Waiting ~4 minutes for any debugging attempt to dump some output in a GitLab artifact that I then have to download and parse manually is not very effective 😅

Any ideas on what I'm missing here?

The tools won't necessarily already be available unless you're using the -full images. The default images do not come with tools preinstalled.

Also, you should not worry about the "inefficiency" of running install-tool because if the same tool/version were already installed then it won't take up any time at all and returns immediately

[jzaefferer]

Thanks for those details. That at least confirms my approach is going in the right direction.

Any ideas why expo/package.json can't be found? It looks like node_modules is empty, yet yarn install says there's nothing to install.

[viceice]

you probably use yarn V1 and we install a patched version. you need to disable skip install to get node modules

[jzaefferer]

Thanks. Adding skipInstalls: false, to my config.js helped with that.

Now some other part of pod install is failing 🙄 This feels like I'm going down the wrong rabbit hole.

[jzaefferer]

PS: https://docs.renovatebot.com/self-hosted-configuration/#skipinstalls says the default is null, which seems misleading if it's implicitly true.

Though I don't think I ever would've found this option without your answer here 🤷

[jzaefferer]

We're probably going to solve this by pinning the few dependencies we have in Podfile and deleting Podfile.lock from our git repo.

Thanks @rarkins and @viceice for your help and such a great tool!
