|
|
The pristine command compares the installed gems with the contents of the
|
|
cached gem and restores any files that don't match the cached gem's copy.
|
|
|
|
If you have made modifications to your installed gems, the pristine command
|
|
will revert them. After all the gem's files have been checked all bin stubs
|
|
for the gem are regenerated.
|
|
|
|
If the cached gem cannot be found, you will need to use `gem install` to
|
|
revert the gem.
|
|
|
|
If --no-extensions is provided pristine will not attempt to restore gems with
|
|
extensions.
