which gave this output. But when I run ruby -v

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

I get this output. I added all the paths in .bash_profile and then I run fastlane env or fastlane init inside the android/ folder or anywhere it is giving me this error

After trying sudo gem install fastlane it says 

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

But when I again write fastlane env or fastlane init it gives me same above error

    Welcome to stackoverflow. Make sure you use code blocks instead of blockquotes when pasting in console output. It's much easier to read that way. More [here](https://stackoverflow.com/editing-help). – anothermh Dec 11 '19 at 19:31
  • Interestingly enough, I am having the exact same problem. – Chase Roberts Dec 12 '19 at 13:57

Based on this thread (thanks for @lwj Answer):

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

1- It might need to uninstall cask fastlane first:

brew cask uninstall fastlane

2- Then Install it using RubyGems:

sudo gem install fastlane -NV

Also because Apple has changed the default shell to zsh, referring to @fdg13gustav answer: https://stackoverflow.com/a/58310864/1995358

3- Create .zprofile file in your home directory

And regarding this thread: https://github.com/fastlane/fastlane/issues/12609

4- Add these lines to your ~/.zprofile file: 

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

I've found a "temporary workaround" to resolve this based on this issue on the fastlane GitHub repo.

After installing fastlane either via brew cask or gem, try running the following commands:

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

This fixed the issue for me, as of now.
