无法安装 Fastlane

sudo gem install fastlane 卡住然后出现下列错误

GET https://gems.ruby-china.com/api/v1/dependencies?gems=memoist,os
200 OK
ERROR:  While executing gem ... (Gem::DependencyResolutionError)
    conflicting dependencies faraday (~> 0.12) and faraday (~> 1.0)
  Activated faraday-1.0.0
  which does not match conflicting dependency (~> 0.12)

  Conflicting dependency chains:
    fastlane (= 2.176.0), 2.176.0 activated, depends on
    faraday (~> 1.0), 1.0.0 activated

  versus:
    fastlane (= 2.176.0), 2.176.0 activated, depends on
    google-api-client (>= 0.37.0, < 0.39.0), 0.37.0 activated, depends on
    googleauth (~> 0.9), 0.9.0 activated, depends on
    faraday (~> 0.12)

  Gems matching faraday (~> 0.12):
    faraday-0.17.3, faraday-0.15.4, faraday-0.15.0

解决方案

gem update慢就用下面的方法

sudo gem uninstall faraday
sudo gem uninstall google-api-client
sudo gem uninstall googleauth
sudo gem uninstall fastlane
sudo gem install fastlane -v 2.162.0

方案2

sudo gem update
