如何修復Ruby / Rails本地環境

Question

我以某種方式弄亂了Rails的安裝，因此我需要幫助重新安裝/修復它。 這是錯誤。

gem install rails -v 4.1.1

Answer 1

這似乎是在全局安裝中出現RVM問題的另一種情況，不是嗎？ 如何在主目錄下安裝？

https://rvm.io/rvm/install （請參閱“單用戶安裝位置：〜/ .rvm /”）

另外，要考慮的事項：

Answer 2

好的，所以我通過卸載rvm進行了修復

rvm implode

這將刪除rvm /目錄以及其中內置的所有紅寶石。 為了刪除rvm的最終痕跡，您也需要刪除rvm gem：

gem uninstall rvm
