I encountered a "You don't have write permissions" error when installing an older version of Rails

I have read the related answers, but the content is too complicated and I am not sure how to do it.

Since I inherited an old project, I need to use Ruby version 2.3.1, I cannot install the latest version of Ruby, nor can I install the latest version of Rails (must match the Ruby version).

I installed Rails under the following instructions on the MacOS terminal:

gem install rails -v 4.2.2

But after a few lines of messages, an error message appears as follows

While executing gem ... (Gem::FilePermissionError)

     You don't have write permissions for the /Library/Ruby/Gems/2.6.0 directory.

I'm not sure if I chose the wrong version of Rails, or there are other operational errors. Please tell me what should I do?

I just moved from Windows to MacOS.

I added "--user-install" at the end of the original instruction to proceed to the next step:

gem install rails -v 4.2.2 --user-install
