Could not find jquery-rails-2.0.0 in any of the sources
After googling this error, the response seems to be to delete Gemfile.lock, then running bundleagain. This works, but then I have different versions of gems where I haven't specified a version in Gemfile. Is there a way to fix this error without deleting Gemfile.lock? I'm using Rails 3.2 and Ruby 1.9.3.
谷歌搜索此错误后，响应似乎是 delete Gemfile.lock，然后bundle再次运行。这有效，但是我有不同版本的 gems，我没有在Gemfile. 有没有办法在不删除的情况下修复这个错误Gemfile.lock？我使用的是 Rails 3.2 和 Ruby 1.9.3。

According to rubygems.org, jquery-rails 2.0.0 has been yanked. That explains the error you had with jquery-rails.
据 rubygems.org 称，jquery-rails 2.0.0 已被yanked。这解释了您使用 jquery-rails 时遇到的错误。
Running $ bundle update jquery-railswill rebuild your gem snapshot. That way you don't have to delete Gemfile.lock
运行$ bundle update jquery-rails将重建您的 gem 快照。这样你就不必删除 Gemfile.lock

An old version of bundler was giving me this same issue. After a bunch of puzzling, I realized that this was the issue.

bundle update jquery-railswill update just the jquery-railsgem, which is likely what you're looking for. Running bundle updateis the equivalent of deleting Gemfile.lockand is not recommended in most cases. See here: Heroku push rejected: can't find jquery-rails-2.0.0 in sources
bundle update jquery-rails将只更新jquery-railsgem，这可能是您正在寻找的。运行bundle update相当于删除Gemfile.lock，在大多数情况下不推荐使用。请参阅此处：Heroku 推送被拒绝：在源中找不到 jquery-rails-2.0.0

I've found it safest ALWAYS to specify gem versions, and only change them when necessary. Saved me a LOT of trouble.
我发现始终指定 gem 版本是最安全的，并且仅在必要时更改它们。为我省去了很多麻烦。
