Installing Ruby version using rbenv

Question

I have been trying to install React Native into my Mac. In the installation docs, it requires Ruby version of 2.7.6 have been to be installed.

I have installed a new Ruby version using rbenv manager and it was successful. But now I cannot switch my machine to new Ruby version. Any help will be highly appreciated.

Thanks!

Answer 1

You have to set the version for the directory where your react project is. You can do this with:

rbenv local 2.7.6

This creates a file called .ruby-version in the directory, which tells rbenv what version of Ruby to use.

This is all visible in the README of rbenv .

Answer 2

You can have a look at this solution

Use the below command to change your ruby version:

rbenv global 3.1.2   # set the default Ruby version for this machine
# or:
rbenv local 3.1.2    # set the Ruby version for this directory

You can find this from rbenv Official Github Repo
