Try installing libqt via homebrew.
$ brew install qt@5.5

Solution for Linux.
Ubuntu
sudo apt-get install libqt4-dev libqtwebkit-dev
Debian Stable
sudo apt-get install libqt4-dev
Fedora
yum install qt-webkit-devel
Fedora 16
yum install qtwebkit-devel
This works for me maybe it will be also helpful for somebody.

brew install qt@5.5
and then
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.

Was having exactly this problem trying to install capybara-webdriver on CentOS 6 after installing QT.
Fixed the problem by adding the following to my PATH environment variable
/usr/lib64/qt4/bin/
回答5:
For OSX, I had to
brew install qt

sudo gem install capybara-webkit -v '0.7.2'
without sudo it would error

macOS Sierra 10.12, El Capitan 10.11 and Yosemite 10.10
Install with either homebrew or macports Homebrew
Qt 5.5 is the last version of Qt that capybara-webkit will support. The Qt project has dropped the WebKit bindings from binary releases in 5.6.
Install Qt 5.5 with homebrew:
brew install qt@5.5
The Homebrew formula for qt55 is keg only which means binaries like qmake will not be symlinked into your /usr/local/bin directory and therefore will not be available for capybara-webkit.
To force Homebrew to symlink those binaries into your /usr/local/bin directory you can run:
brew link --force qt55
After running this command you should get the following output:
$ which qmake
/usr/local/bin/qmake
Macports
Install qt5 with macports:
sudo port install qt5 qt5-qtwebkit # It's not qt5-mac anymore.
The default location for qt5's qmake is /opt/local/libexec/qt5/bin/qmake. If the qmake on path is different, you can indicate the correct one with QMAKE environment variable.
QMAKE=/opt/local/libexec/qt5/bin/qmake gem install capybara-webkit

QT was the answer for me, thougtbot provide a comprehensive installation options here:
https://github.com/thoughtbot/capybara-webkit/wiki/Installing-Qt-and-compiling-capybara-webkit
Generally depending on where you have home brew, this worked for me:
brew update
brew install qt
gem install capybara-webkit
回答8:
For Debian & Ubuntu
sudo apt-get update
sudo apt-get install g++ qt5-default libqt5webkit5-dev gstreamer1.0-plugins-base gstreamer1.0-tools gstreamer1.0-x

On OSX Mavericks 10.9, qt5 does not install qmake. This post was the only thing that worked for me.
Step 1: Download Qt 5.2.0-beta-1-clang HERE.
Step 2: Install it and include the Src files.
Step 3: Symlink qmake into your /bin directory from the location where you installed Qt. The default location is in your home directory. Open a shell and do something like:
ln -s /Path/to/where/you/installed/Qt5.2/5.2.0-beta1/clang_64/bin/qmake /usr/local/bin/qmake
Then gem install capybara-webkit.

Reference: Capybara Installation
回答12:
For fedora
yum install qt-webkit-devel
export QMAKE=/usr/bin/qmake-qt4
gem install capybara-webkit
回答13:
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
回答14:
I've got error in my mac OS X 10.12, and this fixed the problem.
brew install qt5
brew link --force qt5
gem install capybara-webkit
