Gem Capybara-webkit On macOS High Sierra 10.13 Webkit gem

Question

Appologies if this appears like a duplicate question but "Stumped" is the word.

Thank the Lord for this place. (And the contributors)

I have followed all instructions from the Stackoverflow questions relating to this. I have spent countless hours both at work and my evenings. I have successfully installed and used this gem on Ubuntu/Debian machines in the past including headlessly on a Google cloud based Debian instance.

I have followed the instructions from the site below using brew. https://github.com/thoughtbot/capybara-webkit/wiki/Installing-Qt-and-compiling-capybara-webkit#macos-sierra-1012

$  brew install qt@5.5 --with-qtwebkit

results in

Warning: qt: this formula has no --with-qtwebkit option so it will be ignored!

$ which qmake

gives

/usr/local/opt/qt@5.5/bin/qmake

Then I run

$ brew link --force qt@5.5

Then I run

~$ QMAKE=/usr/local/opt/qt@5.5/bin/qmake gem install capybara-webkit -v '1.14.0'

I have successfully installed Xcode via the App Store.

But try as I might.....

~$ QMAKE=/usr/local/opt/qt@5.5/bin/qmake gem install capybara-webkit -v '1.14.0'

Only results in the following output.

Building native extensions.  This could take a while...

I have run the suggestion contained in the above output

$ /usr/bin/xcodebuild

Which gives

xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

$ echo $PATH

gives /Users/matthew/.rbenv/bin:/Users/matthew/.rbenv/shims:/usr/local/opt/qt@5.5/bin:/Users/matthew/.rbenv/shims:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

As for the line....

Check the mkmf.log file for more details.

I'd love to if I had any idea where to find it. I suppose it exists on the filesystem somewhere?

Any help is much appreciated. From my reputation points I'm still pretty green. I just can't proceed without being able to get this working.

Thanks to all of the contributors to this place.

Cheers

No way!!

I'm finally able to contribute to SO. (Even if I am only answering my own question)

(And even if it is only to say that I found the answer while on GitHub. There's an issue that Addresses this.) (And it probably means that this is a duplicate of the same question)(please don't hurt my reputation)(Which seems to happen to me quite regularly)

Turns out the issue is to do with the line

Project ERROR: Xcode not set up properly.

from the above output.

Thankyou https://github.com/vassilevsky

https://github.com/thoughtbot/capybara-webkit/issues/948

The offending line being (Drum roll)

@vassilevsky it looks like you just need to accept the Xcode license. You can do that with:

sudo xcode-select -r

Tada!
