An error occurred while installing eventmachine (0.12.10), and Bundler cannot continue.
Make sure that `gem install eventmachine -v '0.12.10'` succeeds before bundling.
然后，当我尝试所需版本的eventmachine时，我得到了以下输出：
$ sudo gem install eventmachine -v '0.12.10'

我有以下设置：
$ rake --version
rake, version 0.9.2.2
$ ruby -v

如何解决此问题？
答案 0 :(得分：0)
据我所知，这个版本似乎存在问题，我找到解决此问题的唯一方法是thread。我的建议是查看Gemfile.lock并查看哪个gem需要该版本，并考虑是否确实需要它或检查该gem是否更新，因为这是一个非常旧版本的eventmachine。
