When I set out to learn Jekyll, one of the more frustrating things was setting up a dev environment to work with Jekyll locally. I’m not even a Ruby beginner, so the terminology means very little to me.

I took it upon myself to document all the steps it takes to set up a Jekyll development environment and so far things are going well. However, I am now at the point where I share the steps to configure rbenv and there are some problems.

Here’s the TLDR video where I point out the issues at 3:44 (this is an unlisted video):

According to the official Jekyll Docs, I follow these steps:

```auto
rbenv install 3.0.0
rbenv global 3.0.0
ruby -v

```

And I should get this result:

```auto
ruby 3.0.0p0 (2020-12-25 revision 95aff21468)

```

Granted, in my video, I install 3.0.1, but the same problem exists. That problem is the global rbenv environment never changes from the macOS default install of Ruby, which in my case is 2.6.3.

I can use the steps provided by `rbenv init` To get 3.0.1 installed, but it only remains the current version of Ruby in that one terminal window.

How can you use rbenv to set a default Ruby version so it can be used universally (until or unless you want to change it again)?

Thanks!

In the video, it looked like you didn’t add `eval "$(rbenv init -)"` to your `.zshrc` file. That’s the code that sets up paths for Ruby binary and gems. Zsh loads `~/.zshrc` every time a shell starts (i.e. every time a Terminal window opens), so without the change you only get the default system paths, with the system Ruby.

```auto
# Load rbenv automatically by appending
# the following to ~/.zshrc:

eval "$(rbenv init -)"

```
