試圖部署一個Rails 4應用程序到WebFaction，使用他們的文檔，並在本地得到一個錯誤

Question

我想部署一個Rails 4應用程序通過github通過Capistrano 2.15.5 Webfaction。起初我安裝Capistrano的3，並收到錯誤，所以我結束了Capistrano的安裝和2.15.5以下webfaction的文檔here：

我webfaction說話，他們建議我試試老帽2版本，因爲這是他們在做什麼熟悉並且不會更新他們的Capistrano 3的文檔一段時間。

我通過他們的教程的所有適當的步驟獲得，並試圖運行時，我收到了一堆錯誤「帽部署：安裝」或「帽部署：檢查」等

錯誤的引擎收錄， here：（和如下圖所示）

我試圖尋找到這些文件，但我不能確定真正的問題是什麼，我不知道足夠的紅寶石來解決。我希望你能幫助我。

任何幫助將IMMENSELY讚賞和gittipp'ed！ :)

Answer 1

你在ruby v2.0下使用「gem install」安裝了Capistrano 2嗎？

RVM 2.0.0 創業板安裝Capistrano的「你的版本」

試試這個第一....

Answer 2

我猜你設置你的項目的配置與Capistrano的3，我想設置對於Capistrano 2是不同的。

我不是太熟悉的差異，但你得到的錯誤是cannot load such file -- capistrano/setup和this post約Capistrano的3個引用require 'capistrano/setup'如在Capistrano的3生成Capfile之中。

所以我猜這個文件對於capistrano 2是不存在的。我不知道capistrano 2是否有你可以運行的生成器，並讓它們覆蓋你擁有的文件，但是如果是這樣的話，試試吧？

或嘗試取出該行，看看你是否得到不同的錯誤？或者在您開始設置capistrano 3的位置恢復提交併使用capistrano 2完全啓動配置過程？

Answer 3

我在使用第2.15.5版部署我的rails 4應用程序時遇到了同樣的錯誤。我做了研究，發現問題在於語法，因爲我從第3章切換到第2章。所以，如果您使用cap v2，只會在capfile中加載命令，並且僅在deploy.rb中使用Require命令。因此，如果您從3切換到2，請記住語法，因爲cap v2和cap v3之間有很多變化。

注意：部署導軌4應用程序2.15.5是穩定的capistrano版本，您可以使用。這裏是指導鏈接工作對我來說：https：//gist.github.com/brobertsaz/8660415
