Capistrano部署失敗rvm-shell說rvm沒有被發現

Question

最近我繼承了一個Rails應用程序，已經部署到生產中很多次。我以前部署到臨時環境。現在，它無法部署到任一個。然而，另一個部署到具有相同帳戶的相同服務器的Rails應用程序成功部署了使用rvm和capistrano。

我收到以下錯誤：

我已經檢查了服務器。 RVM已安裝並正在運行。

Answer 1

這是一個rvm/rvm-capistrano版本不匹配。檢查服務器上安裝的rvm的版本，並與捆綁安裝的rvm-capistrano版本進行比較。如果您的服務器具有rvm 1.18.x，則將Gemfile中的rvm版本鎖定爲1.2.x. rvm-capistrano 1.3.x需要rvm 1.19.x.

我在回答我自己的問題，因爲我必須弄清楚這個難題。回想起來很明顯，但是當你第一次看到這個錯誤的時候並不是這樣。這是沒有在Gemfile中指定產品版本的情況。通常，我們廣泛的測試套件會捕獲這樣的問題，但是我們的測試套件並未覆蓋部署，所以我們錯過了這個測試套件，直到爲時已晚。
