Error after upgrade prevents package.json and yarn.lock from being updated · Issue #86 · ds300/patch-package (original) (raw)

When I try to upgrade a dependency (using yarn upgrade) and I get a new patch failure error from patch-package, I'm left in a weird state where my node_modules do reflect the changes, but my package.json and yarn.lock do not.

My presumption is that the patch-package error stops Yarn from commiting the update to the manifest and lockfile. I'm not sure this is desired behaviour, or whether this is a patch-package problem or a Yarn problem.

Because of the error message, I thought it was safe to go in and re-apply my patch. So I edited node_modules and ran patch-package to generate the new patch, but because the upgrade was not committed, patch-package created a patch of a diff between the version before the upgrade and the version after the upgrade with my changes, which took me awhile to realise.

If we can't fix the bug whereby upgrades are not committed due to the error, we should provide clearer steps in the error message to avoid this.
