An error occurred while installing json (1.8.1), and Bundler cannot continue. Make sure that gem install json -v '1.8.1' succeeds before bundling. xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
make failed, exit code 1
I know this has already been posted but i have tried bundle update, bundle install and putting the gem file in my gem file and bundle install but nothing works from the other answers.
ideas?
