Maybe it’s been a lot of years and many projects along the way that you have been using Ruby on Rails to develop your projects. Turn things from paper into actual software that makes other people’s lives easier. Of course, it’s hard to learn everything in the beginning and expect to remember all of it for the rest of your life. That’s why we write them, bookmark a link, etc.

One such thing that you may have probably missed, as I also found out about it only today, is seeing the versions of all the gem versions that you are using.

To do that, you simply need to execute at the project directory that you are in from your terminal:

bundle show

After that, you should see a list of all the gems that you have installed and their corresponding versions on the right.

This is something that may be useful for you when you are trying to track the exact version of the gem files that you are using and Google solutions for those specific versions. Maybe you are preparing the technical documentation that you have to write to your client.

Or maybe, there’s something else that you just want to know and hope that it becomes useful in the future. Either way, this just something that you can use at a point in your development career that can be worth knowing.
