Package has been ignored because it contains invalid configuration

Describe the bug I’m seeing this error a lot recently across my project. I can’t say for sure when it occurred but seems to have been with some recent package updates.

Error is below

warn Package @fortawesome/pro-light-svg-icons has been ignored because it contains invalid configuration. Reason: Cannot find module '/Users/runner/work/1/s/node_modules/@fortawesome/pro-light-svg-icons/package.json.js'
warn Package @fortawesome/pro-regular-svg-icons has been ignored because it contains invalid configuration. Reason: Cannot find module '/Users/runner/work/1/s/node_modules/@fortawesome/pro-regular-svg-icons/package.json.js'
warn Package @fortawesome/pro-solid-svg-icons has been ignored because it contains invalid configuration. Reason: Cannot find module '/Users/runner/work/1/s/node_modules/@fortawesome/pro-solid-svg-icons/package.json.js'

It seems to be hanging a lot of build commands and gets thrown during a lot of react native and yarn commands.

Reproducible test case react-native run-android

Expected behavior No warning should be thrown

Desktop (please complete the following information):

• “react-native”: “0.66.3”
• “@fortawesome/fontawesome-svg-core”: “6.1.1”
• “@fortawesome/pro-light-svg-icons”: “6.1.1”
• “@fortawesome/pro-regular-svg-icons”: “6.1.1”
• “@fortawesome/pro-solid-svg-icons”: “6.1.1”
• “@fortawesome/react-native-fontawesome”: “0.2.7”

Seems like its looking for package.json.js paths when it should just be package.json…?

Understood, thank you for the explanation!

I’m not the biggest fan of having local packages laying around and having to re-create the local package every time I want to use a new icon so I’ll probably just bite the faBullet. Hold the faPhone - that icon doesn’t exist? Oh well… Thanks again, I appreciate your time!

Yeah sorry about forcing the change over. The problem is that react-native doesn’t support tree-shaking. And your instinct is correct, it’s just the sheer number of icons. We added a bunch in 6 and it’s a blessing and a curse.

I will say just as an alternative you could use our Desktop Subsetter and create a subset of the icons that you use. One of the things that you will get from the subset (a .zip file) is a directory of JS packages. These are formatted exactly like our full packages. You could install these and it would speed things up tremendously.
