我在我的 Gemfile 中添加了一个 gem 'koala',当我运行 'bundle install' 命令时,似乎已经抛出了 gem 版本:
Bundler could not find compatible versions for gem "faraday":
In snapshot (Gemfile.lock):
faraday (0.6.1)
In Gemfile:
koala (~> 1.2.0beta1) depends on
faraday (~> 0.7.4)
Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.
我该如何解决这个冲突?
