Fastlane folder generated into project directory but, no file were there. I just tried to generate a build from "Fabric" Mac App, still am getting the error (Find the screenshot.) Any guidance? Thanks.

Answer 1

Mike from Fabric. I'd recommend switching from fastlane in Fabric to using it independently. Here's how to do it, referenced from Felix Krause.
In terminal, run:
rm -rf ~/.fastlane/bin
-- This removes the current fastlane installation from your home directory.
rm -rf /usr/local/lib/fastlane_lib
-- This removes the current fastlane installation from your system.)
After, edit your ~/.bashrc or ~/.bash_profile and remove any reference to fastlane. We're clearing everything out so that you can set up a fresh install.
Now, navigate to your project directory and run touch Gemfile. Add the following content to that file:
source "https://rubygems.org"
gem "fastlane"
Save the file and run bundle update. Commit both the Gemfile and the Gemfile.lock to version control and from now on, every time you run fastlane, prefix your command using bundle exec:
bundle exec fastlane beta
Finally, restart the Fabric macOS app and you'll be all set.
