The last computer I installed capybara-webkit on did not require full xcode, only the command line tools. However, now when I try to install it on a new computer, I run into the following:
Try to install:
$ gem install capybara-webkit
Get error about license: Project ERROR: Xcode not set up properly. You may need to confirm the license agreement by running /usr/bin/xcodebuild.
Try to accept license: $ xcodebuild -license
Get error about only having command line tools: xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance
At this point I've just given up and started installing xcode, but it seems silly that I have to install a 4.5GB IDE just so I can accept a license agreement for the command line tools. Is there any way around that?
As you can read in capybara-webkit wiki and in QT wiki, it is not possible, as capybara-webkit requires QT.
Qt 5 sadly requires the full Xcode to be installed (> 5 GB), as opposed to previous versions of Qt which didn't. NB: We warn against using tools that try to avoid installing the full Xcode by overwriting system files in /usr/bin, since that has caused problems for other users, forcing them to reinstall OSX.
Building on OSX currently requires at least XCode version 5.1. This will remain a requirement for Qt WebEngine. Changing it would require significant changes to the Chromium code base that are going against the direction Chromium is being developed.
