Babel Error: `@babel/plugin-proposal-private-property-in-object ` explicit dependency
j3tan opened this issue · 6 comments
Hitting a newly introduced error message in babel
version 7.22.5
causes the following error:
--- PLACEHOLDER PACKAGE ---
This @babel/plugin-proposal-private-property-in-object version is not meant to
be imported. Something is importing
@babel/plugi-proposal-private-property-in-object without declaring it in its
dependencies (or devDependencies) in the package.json file.
Add "@babel/plugin-proposal-private-property-in-object" to your devDependencies
to work around this error. This will make this message go away.
Since packemon
uses @babel/plugin-proposal-private-property-in-object
for babel config, it needs to explicitly declare it as a dependency.

@j3tan This is a weird one. I'm not importing @babel/plugin-proposal-private-property-in-object
anywhere.
But I am importing @babel/plugin-transform-private-property-in-object
which is different (note transform vs proposal). There were renamed in 7.22: https://babeljs.io/blog/2023/05/26/7.22.0#renamed-packages
Maybe node modules in a weird state? Does deduping fix it?
I'll dig a bit deeper anyways.
I can't seem to reproduce this. Is it just being logged to the console during a build?
@milesj My bad, this may be due to using an older version of packemon
. I had not realized you moved away from the proposal package 2 weeks ago and we definitely haven't bumped since before that.
I'll verify and close if that is the case
Some repos are still using packemon@2.x so we're using yarn resolutions to bypass the warning for now.
Yea this was fixed in 3.1.1. I'll leave this open for now in case there's more issues around it.
