Setup Errors for Rails on MacOS 10.14 Mojave

Jerrica Johnson asked in General

Hello everyone!
I have already installed Ruby Environment, but each time I try to install Rails on MacOS, it's giving me the following errors:
Jerricas-MacBook-Pro:test_app jerricajohnson$ rails -v

require': cannot load such file -- bootsnap/setup (LoadError)

Does anyone know what this means? I'm pretty new to the coding game.

Hey Jerrica,

Looks like maybe you're just missing this line in your Gemfile:

gem 'bootsnap', require: false

Try adding that and running bundle afterwards to install it.

It's basically just trying to load bootsnap but it can't find it. Bootsnap is a tool to make loading Rails faster. https://github.com/Shopify/bootsnap#how-does-this-work

Hello! Thanks for the response. I'm inputting that into the terminal. It keeps saying 'unknown command bootsnap'.

Oops, sorry I wasn't clear. That line of code goes in the Gemfile file, not in the terminal.
