找不到兼容版本的gem＆＃34; faraday＆＃34;

Question

在安装gem时，我不明白这里的问题是什么。以下是错误日志的详细信息

Bundler could not find compatible versions for gem "faraday":
In snapshot (Gemfile.lock):
faraday (= 0.12.1)

In Gemfile:
faraday

mailchimp3 (= 1.3.1) was resolved to 1.3.1, which depends on
  faraday (~> 0.9.1)

stripe was resolved to 2.10.0, which depends on
  faraday (~> 0.9)

仅供参考：我使用的是rails 5，ruby 2.4.1。
