我的宝石文件包括:

group :production do
  gem 'pg',             '0.17.1'
  gem 'rails_12factor', '0.0.2'
  gem 'puma',           '2.11.1'
end

当我发出bundle install命令时,最后我得到了这条线

"Your bundle is complete!
Gems in the group production were not installed.
Use `bundle show [gemname]` to see where a bundled gem is installed."

如何安装生产组.

我想放弃当前分支中的更改而不提交,我不小心输入了命令git revert HEAD.prev分支(之前提交的)的变化似乎丢失了？

如何撤消git revert HEAD命令？
