Summary

You get no warning and shrinkwrap errors appear if you attempt to update a package to a later version which is being overridden by pnpm-config.json's globalOverrides feature.

Repro steps

1. Go to pnpm-config.json, add globalOverrides property and add an entry being setting it to current version of a package today.
2. Run rush update --recheck a. You should see successful lockfile update created in git
3. Try to update the version of that package (in some project)
4. Run rush update

Expected result: Few Expectations:

• User is alerted that they are trying to update a package which is being overridden by pnpm-config.json

• rush update fails (perhaps in rush check stage) with the same error

  Actual result: You get the following warning which says the shrinkwrap file contains issues:

  

This terminal feedback appears unclear as it looks like your build has successfully completed, however you don't have a new lockfile, and in CI your build will fail because of this error.
