现在，当我用命令启动我的应用程序时：
bundle exec unicorn -c my_unicorn_config.rb -d
我在错误日志中得到了这个：

为什么bundler / runtime.rb无法加载我的宝石？
我还用export GEM_HOME="${HOME}/myapp/shared/bundle/ruby/1.9.1/gems"定义了我的宝石env变种
以及export GEM_PATH="${GEM_HOME}"
编辑：
我的捆绑检查输出确实显示所有deps都满意：
[myapp@myapp appuser]$ bundle check
Your Gemfile lists the gem uuidtools (>= 0) more than once.
You should probably keep only one of them.
While it's not a problem now, it could cause errors if you change the version of one of them later.
The Gemfile's dependencies are satisfied
答案 0 :(得分：0)
它找不到activerecord，它找不到sinatra-activerecord，它找不到haml-contrib。你确定你运行了bundle吗？
如果这没有帮助，我的下一步就是升级到ruby 2.1或2.2，它没有那么大的痛苦。
答案 1 :(得分：0)
你确定你拥有所需的所有宝石吗？
我试图安装你的版本的ruby 1.9.3-p551 （通过rvm）。当我尝试通过gem安装任何东西时，它显示以下错误消息：
YAML safe loading is not available. Please upgrade psych to a version that supports safe loading (>= 2.0).
我必须通过以下方式修复它：
gem install psych -v 2.2.4
您的错误表明您错过了它或某处有旧版本：

你可以尝试一下，安装psych正确的版本，如果有帮助吗？
注意： psych已成为1.9.2的MRI ruby的一部分。但是，您可能需要更新的版本，即gem。
