Composer error when installing or branching to dev/php8

[poplarmedia]

The following error occurs when branching to dev/php8 from current master. I reverted to develop for now. With develop I am able to connect to a Providence dev/php8 instance which is running without issue on same server.

Automatic installation of the required vendor libraries failed: Library installation failed: Installing dependencies from lock file (including require-dev); Verifying lock file contents can be installed on current platform.; Warning: The lock file is not up to date with the latest changes in composer.json.

Please remove the lock file and vendor libs and run composer again.

When I tried to branch back to 'dev/php8' from 'develop' I got this error in terminal: error: The following untracked working tree files would be overwritten by checkout: composer.lock

I deleted the file, ran the command again: git checkout dev/php8

I was able to access Pawtucket with out issue. No deletion of vendor libs required.

Is this because it was an upgrade from master--which prompted the error above vs. upgrade from develop? I recall a similar fail happened on a clean install last week, but did not document the details. I just reverted to develop and then upgraded to dev/php8 as a second try.

The lock file is not in Git; when you switch branches composer.json changes but not the lock file which are now out of sync. I believe that's the issue. If the problem persists try deleting the lock file and clearing out vendor after switching branches, then run composer up
