An error occurred while installing thin (1.7.2), and Bundler cannot continue.
Make sure that `gem install thin -v '1.7.2' --source 'https://rubygems.org/'` succeeds before bundling.
Solution

  • disabling the error fixed it:

    bundle config build.thin --with-cflags="-Wno-error=implicit-function-declaration"
