Answer 1

brew install qt@5.5

gem install capybara-webkit -v '0.7.2'

-v 0.7.2 is to select version project is asking you to install. See that installing qt from http://developer.qt.nokia.com/wiki/Support_for_Mac_OS_X requires to set PATH variable.

Answer 2

I was able to get qt and capybara-webkit installed and working on OS X. I had to install Xcode so the build for

gem install capybara-webkit

would finish.

I also set this in my environment

Capybara.javascript_driver = :webkit

brew install qt5 to get latest qt.

The docs for it say that it conflicts with qt4, so be sure to remove that first with

brew uninstall [old qt]

Then it needs to be symlinked with

brew link --force qt5

Answer 3

For fedora

yum install qt-webkit-devel
export QMAKE=/usr/bin/qmake-qt4
gem install capybara-webkit

Answer 4

Answer 5

For OSX, I had to

brew install qt

and then

sudo gem install capybara-webkit -v '0.7.2'

without sudo it would error
