我希望使用rbenv在Ubuntu 14.04服务器上运行Gollum的开发版本来管理ruby和gem版本。我使用以下命令来构建和安装gollum。如果我首先使用rbenv shell system来绕过rbenv，那么我就能够构建并正确运行。
rbenv install 1.9.3-p551
rbenv rehash
git clone git@github.com:gollum/gollum.git
cd gollum
rbenv local 1.9.3-p551
gem install bundle
rbenv rehash
bundle install
rake build
gem install --no-ri --no-rdoc pkg/gollum-4.0.0.gem
然后运行gollum会导致以下错误：
[dkozel@server gollum] gollum
/home/dkozel/.rbenv/versions/1.9.3-p551/lib/ruby/1.9.1/forwardable.rb:204: stack level too deep (SystemStackError)
我试过干净安装ruby版本和所有宝石，在vendor / bundle中安装gem，构建Gollum的不同发布标签，并使用Ruby 2.2.2而不是1.9.3p551。
使用额外的调试标志从~/gollum/bin运行gem会产生完整的跟踪。
[dkozel@server bin] ruby -wdS gollum
