我已经在我的服务器Redmine 1.1.x 上使用了一段时间，我正在尝试将其升级到 2.2.2。我遵循了升级顺序，现在该应用程序不再工作了：

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.
bicou@ssh:~/redmine-2.2.2$ bundle show builder
/home/bicou/gems/gems/builder-3.0.0
bicou@ssh:~/redmine-2.2.2$ env | grep gem
GEM_HOME=/home/bicou/gems/
PATH=/home/bicou/gems/bin:/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games
GEM_PATH=/home/bicou/gems/
如您所见，安装了builder v3.0.0。是什么赋予了？
我所做的尝试：
- 删除 Gemfile.lock 并
bundle install再次运行 - Paulo Fidalgo 的建议（见下文）
根据 Paulo Fidalgo 的建议：
我的 Gemfile 包含 builder 3.0.0：
bicou@ssh:~/redmine-2.2.2$ grep builder Gemfile
gem "builder", "3.0.0"
bicou@ssh:~/redmine-2.2.2$ bundle update
