Uninstalling a Gem1:24 with Jason Seifer
It is equally as important to be able to remove a gem as it is to install one.
Sometimes you'll get into a scenario where a gem 0:00 needs to be removed from your Ruby installation. 0:03 This can be the entirety of the gem, or just a specific version. 0:06 Let's see how to uninstall a gem now using workspaces. 0:11 Equally as important as being able to install a gem 0:16 is being able to uninstall a gem. 0:18 So let's see how that works now. 0:21 If I list by different gems, 0:24 we can see that I have two different versions of money installed. 0:26 In order to uninstall a gem, we use the uninstall command, and 0:30 then the name of the gem that we want to uninstall. 0:35 In this case, it's going to be money. 0:38 After that, Ruby will give us the option to install a particular version, or 0:42 all versions. 0:46 I'm going to uninstall the most recent version. 0:48 And then it shows us that it has successfully uninstalled that version. 0:52 I'm gonna clear my screen here, and install money again. 0:56 Okay. 1:03 Now, if we do gem list, we can see we have both versions of money. 1:04 And if I wanted to uninstall a particular version. 1:09 I can pass in the version flag. 1:14 And that will uninstall the specified version of the gem. 1:19
