试图在本地运行 ruby​​ 网站，说“gemfile states ruby​​ version X, but I have version Y”，然后说我已经安装了 Y，版本是 X

Question

As the titles says: trying to run ruby website locally, says "gemfile states ruby version X, but I have version Y", but then says I already installed Y, and version is X.

I am not a ruby dev I am just trying to test this site locally and make some some minor edits. Thank you.

Answer 1

You have to set the ruby version , when you have multiple versions installed.

version_num - 2.7.2 for your case

For rbenv - rbenv local version_num for current directory, rbenv global version_num to change globally.

If you are using rvm you can set it by rvm use version_num , this will set it only for that particular terminal. If you want to change the default globally check here https://rvm.io/rubies/default
