问题
I'm trying to remove a gem from my project so I went into the gem file and commented it out.
...
gem some_gem
# gem 'gem_I_dont_want'
gem another_gem
....
Then I run
bundle
To check that the gem is gone, I type
bundle show
But I still see the gem there
...
* some_gem
* gem_I_dont_want
* another_gem
Am I not understanding how bundle works? Is there something more I'm suppose to do?
回答1:
The gem could be a dependency of another gem which would explain its presence in bundle show.
If the gem appears indented beneath another gem within the Gemfile.lock file then it would indicate that it's included still because it's a dependency.
回答2:
There is still this gem until you clean your Bundle using:
bundle clean
But you don't need to fear. It mean that this package is installed but it wouldn't load into your app until you let it.
