Rails网站上的Ruby退出（SystemExit）错误

Question

在Dreamhost升级其服务器系统之后，我的网站目前处于关闭状态。 我必须安装成功安装的捆绑程序，当我将站点通过ftp下载到服务器时，错误编码器下降了大约100行。

错误代码为：

exit (SystemExit)
  /home/studioanisewm/studioanise.com/config/boot.rb:65:in `exit'

# All that for this:

Answer 1

根据我在旧的Rails分支中挖掘的内容，从boot.rb文件的65行判断，您的Rails版本约为2.1-2.2。 并且它应该已经打印出确切的版本号以及未安装的警告。 另外，版本2似乎不使用Bundler，因此您必须将宝石与常规rubygems一起安装。 尝试找出您的应用程序确切的Rails版本并运行

gem install -v 2.x.x rails

还有一条建议：您的用户不需要查看乘客的调试信息。 如果可以，请配置它以将详细信息写入日志文件，同时向用户显示简短的错误页面。 因为旅客现在在您的页面上太冗长。 我可以从这种行为预测各种安全问题。
