**After doing so close the terminal session and restart it to start using fastlane ????

它给出了这个输出。但是当我运行ruby -v

ruby 2.6.5p114 (2019-10-01 revision 67812) [x86_64-darwin16]

我得到这个输出。我在 .bash_profile 中添加了所有路径，然后在 android/ 文件夹或任何出现此错误的地方运行 fastlane env 或 fastlane init

在尝试sudo gem install fastlane 之后，它说

Successfully installed fastlane-2.137.0
Parsing documentation for fastlane-2.137.0
Done installing documentation for fastlane after 6 seconds
1 gem installed

但是当我再次写 fastlane env 或 fastlane init 时，它给了我同样的上述错误

欢迎来到stackoverflow。确保在控制台输出中粘贴时使用代码块而不是块引用。以这种方式阅读要容易得多。更多here.
有趣的是，我遇到了完全相同的问题。

【解决方案1】：

基于此线程（感谢@lwj 回答）：

https://github.com/fastlane/fastlane/issues/15740

1- 可能需要先卸载 cask fastlane：

brew cask uninstall fastlane

2- 然后使用 RubyGems 安装它：

sudo gem install fastlane -NV

也是因为苹果把默认shell改成了zsh，参考@fdg13gustav 回答：https://stackoverflow.com/a/58310864/1995358

3- 在你的主目录中创建.zprofile 文件

关于这个线程： https://github.com/fastlane/fastlane/issues/12609

4- 将这些行添加到您的 ~/.zprofile 文件中：

export PATH="$HOME/.fastlane/bin:$PATH"
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

我找到了一个基于this issue on the fastlane GitHub repo 的“临时解决方法”来解决此问题。

通过brew cask 或gem 安装fastlane 后，尝试运行以下命令：

rm -rf $HOME/.fastlane/bin/bundle/lib/ruby/gems/2.2.0/gems/faraday-0.* 
rm -rf $HOME/.fastlane/bin/bundle/lib/ruby/gems/2.2.0/specifications/faraday-0.* 
gem install faraday -v 0.17.0 --install-dir $HOME/.fastlane/bin/bundle/lib/ruby/gems/2.2.0

到目前为止，这为我解决了这个问题。
