各位大能好我在輸入sudo gem install rails時跑出了最下面那一大串敘述幾乎不懂我是看網路教學影片其中用RVM管理ruby 但後來發現這臺mac原本有舊的rbenv跟ruby 導致有點衝突這兩天我上網胡亂抓藥好像亂碰了PATH 現在有點不知道該怎麼重新開始回到最初所以想來此求助如何解決這問題重新上學習rails的軌道 btw 我現在透過rbenv 明明是裝 ruby 3.0.0 但我輸入 ruby -v 卻出現ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.x86_64-darwin19] 可能也是胡亂抓藥的後遺症因為我對mac的系統本身還不太熟如果有大大有點空閒時間可以幫我看看非常感激 =============== 以下這大串： Building native extensions.
