When installing a new version of Ruby I cannot think of a situation in which I wouldn't want Bundler installed too. The good news is that you can get rbenv to install Bundler, or any other gem you like, as soon as you install a new version of Ruby. All you need is the default-gems plugin.
If you installed rbenv with Homebrew, like me, then you can install default-gems with Homebrew too.
$ brew install rbenv-default-gems
Then you need to make a list of gems that you want installed. First create a file named
default-gems in your
$(rbenv root) directory. Mine is located at
~/.rbenv/default-gems. Add the names of the gems you want to install, one per line. You can include an optional version or the option
--pre for a prerelease version. For Bundler you will want the latest release, so the
default-gems file would look like this:
Now when you install a new version of Ruby, Bundler will be installed as well.
You can add other gems that you always use too. If you're a fan of pry, for example, then add a line for it in
default-gems and you'll never have to remember to install it yourself.
There are a number of rbenv plugins which you can check out, but default-gems has always been a must have for me.
Are there any tools or plugins you use that make your Ruby development easier? I'd love to hear about them! Please share your tips with me on Twitter.
