Install fails

[alysonz]

In a desperate attempt to get more information based one this line in the mkmf.log clang: error: linker command failed with exit code 1 (use -v to see invocation) , I added -v
It worked. I can only guess that the command required any kind of config option at all, even if it was invalid.
¯_(ツ)_/¯

$ sudo fastlane add_plugin appicon -v

fastlane update available
Please run `brew update && brew cask reinstall fastlane`
fastlane installation at path:
/Users/alysonzepeda/.fastlane/bin/bundle/lib/ruby/gems/2.2.0/gems/fastlane-2.47.0/bin/fastlane
-----------------------------
fastlane 2.47.0

[EXC-BAD-ACCESS]

i had installed fastlane using brew cask install fastlane and i was getting the same error message as @kaelumania.
i did the following:
sudo rm -rf ~/.fastlane
sudo gem install fastlane
sudo fastlane add_plugin appicon
and it worked

[kaelumania]

It's failing for me as well.

Managed to get it working using:

bundle exec fastlane add_plugin appicon

@RWOverdijk @kaelumania can you please share your mkmf.log file content so we can inspect further?

[alysonz]

@felipeplets I am having the same problem.

Hello :)

I've used rbenv to manage Ruby version, (v2.1.4)
And then used bundle exec fastlane add_plugin appicon to fix
