Capistrano抱怨资产预编译时缺少'eventmachine'

Question

我试图部署到Ryan Bates截屏视频后的VPS。

我用细如Web服务器而不是独角兽和它给我头疼的负荷...... 当试图编译服务器上的资产，它给了我这样的：

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 

我不能检查如果eventmachine安装在捆绑包中，因为capistrano总是将所有内容都回滚，所以我实际上并没有在脚本之后安装应用程序..这使得几乎不可能追溯到更远......

所以我完全失去了。谷歌搜索“耙资产：预编译eventmachine”不返回任何相关的..

谢谢你的帮助。

亲切的问候 斯特凡诺

正如你看到的我swaped薄的麒麟......我想我也把范围缩小到Capistrano的实际上从未叫包安装？因为现在它抱怨没有找到nokogiri。

我设法找到capistrano存储在共享/缓存复制目录下的服务器上的实际版本，并且捆绑安装在那里工作得很好！

是的'用导轨部署很容易！'容易浪费整整一个星期就可以了..

Answer 1

我居然发现了问题...

如果你把你Gemfile.lock的在你的仓库（推荐），你产生Gemfile.lock的Windows机器上你基本上拧紧。

一个从Windows机器Gemfile.lock的会做到这一点：

bcrypt-ruby (3.0.1-x86-mingw32) 

而且在生产环境（Linux版），这将静默失败。

“解决方案”： 不要在您的版本控制中检查Gemfile.lock。这可能会在稍后重新部署时导致问题，并且您的应用程序决定更新它的宝石，因为它会生成Gemfile.lock本身。

的 “真正解”： 不要工作在Windows上。

从您的资料库中删除您Gemfile.lock的事：

git rm Gemfile.lock

你不需要cap deploy:cold，但你需要确保你的capistrano脚本知道bundle install。所有你需要做的是require 'bundler/capistrano'。这应有助于：http://gembundler.com/deploying.html
