Rails控制台無法加載，“找不到gem'rails（= 3.0.0.beta3）紅寶石”

Question

我輸入Rails控制台開始工作，並收到以下錯誤：

幾天前我開始與Rails合作，因此我分析錯誤的能力僅限於Google的能力。 我尚未找到有關Could not find gem 'rails(=3.0.0beta3) ruby

誰能指出我正確的方向？

Answer 1

看起來rails gem已安裝在某個位置，但僅部分卸載或已安裝，但安裝在意外的位置。 第一步是嘗試重新安裝。 我不確定您使用的是系統紅寶石，還是通過rvm / ruby​​-build安裝的系統，因此很難提供更多建議。

Answer 2

它找不到您的rails寶石。 首先嘗試：
