Composer installation - source throw error -prefer-source

When I run composer install --prefer-source or try to update this specific package (others work well), I get this error:

 Failed to download some-bundle from source: Failed to execute git checkout 'xx' -- && git reset --hard 'xx' -- error: The following untracked working tree files would be overwritten by checkout: ... [ list of all files in repo on a branch that interests me ] ... Please move or remove them before you can switch branches. Aborting

I suppose I messed up something in the package repository, but I have no idea what.

  • I am cloning a new project repository
  • I try "install --prefer source linker" and still get this error.

Interestingly, the error only occurs on the docker on the MAC. On another linux pc, it works fine.

It looks like you manually updated the sources in the directory of your vendor for this package.

If so, try to commit / click or reset them directly in the vendor directory before updating the package.

If not, this may relate to this issue: https://github.com/composer/composer/issues/2896

The author writes:

"This can be fixed in two ways:

  • when bonding, add the -include-untracked flag, which will also save the newly added files.

  • when checking, add the --force flag, which will overwrite files and not interrupt. "

If all else fails, you can manually remove the provider directory to force the composer to install the package again. Change See also https://getcomposer.org/doc/03-cli.md#clear-cache , perhaps the composer cached the git repository somewhere and cannot update it.
