我不能用bundle安装sys proctable。即使安装了它也不会停止抱怨：
$ gem install sys-proctable --platform universal-linux

You have requested:
pg = 0.12.2
The bundle currently has pg locked at 0.12.2.
Try running `bundle update pg`
Run `bundle install` to install missing gems.

最佳答案
除非你展示你的Gemfile，否则无法确定，但你要的宝石似乎是sys-proctable-0.9.2，而不是sys-proctable，
确实，在安装之前需要使用bundle config build.sys-proctable --platform univeral-linux才能获得所需的响应，但是gem名称是sys-proctable。
编辑
在这个问题https://github.com/djberg96/sys-proctable/issues/24之后，您似乎可以检查是否可以在irb中实际需要它，如果可以，那么就使用它，查看您可以遵循的恼人的消息，并要求它的路径来自本地目录或直接来自其git存储库。
以gem 'sys-proctable', :git => 'git://github.com/djberg96/sys-proctable.git'
或gem 'sys-proctable', :path => 'path/to/gem/inside/project'
