Capistrano抱怨資產預編譯時缺少'eventmachine'

Question

我試圖部署到Ryan Bates截屏視頻後的VPS。

我用細如Web服務器而不是獨角獸和它給我頭疼的負荷...... 當試圖編譯服務器上的資產，它給了我這樣的：

triggering after callbacks for `deploy:update_code' 
* executing `deploy:assets:precompile' 
* executing "cd /home/deployer/apps/my-app/releases/20120614062157 && b 
undle exec rake RAILS_ENV=production RAILS_GROUPS=assets assets:precompile" 
servers: ["**.**.**.**"] 
[xx.xx.xx.xx] executing command 
** [out :: **.**.**.**] rake aborted! 
** [out :: **.**.**.**] cannot load such file -- eventmachine 
** [out :: **.**.**.**] 
** [out :: **.**.**.**] (See full trace by running task with --trace) 
command finished in 3891ms 
*** [deploy:update_code] rolling back 
* executing "rm -rf /home/deployer/apps/my-app/releases/20120614062157; 
true" 
servers: ["**.**.**.**"] 
[**.**.**.**] executing command 

我不能檢查如果eventmachine安裝在捆綁包中，因爲capistrano總是將所有內容都回滾，所以我實際上並沒有在腳本之後安裝應用程序..這使得幾乎不可能追溯到更遠......

所以我完全失去了。谷歌搜索「耙資產：預編譯eventmachine」不返回任何相關的..

謝謝你的幫助。

正如你看到的我swaped薄的麒麟......我想我也把範圍縮小到Capistrano的實際上從未叫包安裝？因爲現在它抱怨沒有找到nokogiri。

我設法找到capistrano存儲在共享/緩存複製目錄下的服務器上的實際版本，並且捆綁安裝在那裏工作得很好！

是的'用導軌部署很容易！'容易浪費整整一個星期就可以了..

捆綁安裝的作品，如果我做捆綁高管帽部署：

Answer 1

我居然發現了問題...

如果你把你Gemfile.lock的在你的倉庫（推薦），你產生Gemfile.lock的Windows機器上你基本上擰緊。

一個從Windows機器Gemfile.lock的會做到這一點：

bcrypt-ruby (3.0.1-x86-mingw32) 

而且在生產環境（Linux版），這將靜默失敗。

「解決方案」： 不要在您的版本控制中檢查Gemfile.lock。這可能會在稍後重新部署時導致問題，並且您的應用程序決定更新它的寶石，因爲它會生成Gemfile.lock本身。

的 「真正解」： 不要工作在Windows上。

從您的資料庫中刪除您Gemfile.lock的事：

git rm Gemfile.lock

你不需要cap deploy:cold，但你需要確保你的capistrano腳本知道bundle install。所有你需要做的是require 'bundler/capistrano'。這應有助於：http://gembundler.com/deploying.html
