【Mac】rbenv versionsとruby -vでバージョンが違う時の解決法

Posted at

ruby versionsの時

$ ruby 3.0.2p107 (2021-07-07 revision 0db68f0233) [x86_64-darwin20]

ruby -vの時

$ ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.x86_64-darwin20]

Rubyのバージョンが違うことがわかります。
この問題解決に2時間くらいかかったので投稿しようと思います。

解決策

$ echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
$ source ~/.bash_profile
$ rbenv global 3.0.2

結論この3行を上から順番にターミナルに打つと問題解決できました。
めでたしめでたし
