An error occurred while installing capybara-webkit (1.10.1), and Bundler cannot
continue.
Make sure that `gem install capybara-webkit -v '1.10.1'` succeeds before
bundling.

Note: I already tried to look into a post with similar problem Cannot install capybara-webkit gem and tried to follow the solution by executing the following command. But got following error.

> qmake -v
'qmake' is not recognized as an internal or external command,
operable program or batch file.

Answer 1

Installation instructions are in the capybara-webkit wiki - https://github.com/thoughtbot/capybara-webkit/wiki/Installing-Qt-and-compiling-capybara-webkit . You'll want to install Qt 5.5.1 (5.6 is only supported if you build the QtWebKit module separately)

Sayed

I've done that (OSX High Sierra) and the gem install still isn't working: "which qmake" => "/usr/local/opt/[email protected]/bin/qmake" but installing the Gem gives me "Command 'qmake ' failed" – Craigcraighead

@Craigcraighead That's not the error this question deals with which was Command 'qmake ' not available - so this really isn't the place to ask about it. Open your own question with way more details than you've provided here. – Sayed

if you get the error: Error: [email protected]: unknown version :mountain_lion make sure you follow the Note in the documentation: NOTE: If you get Error: [email protected]: unknown version :mountain_lion, comment line #25 in Formula/[email protected] – Isentropic

Ubuntu

sudo apt-get update
sudo apt-get install qt5-default libqt5webkit5-dev gstreamer1.0-plugins-base gstreamer1.0-tools gstreamer1.0-x

In Ubuntu 22.04.1 This gives an error: E: Package 'qt5-default' has no installation candidate – Dorena

Answer 3

'qmake' is not recognized likely means that Qt is not installed

brew update
cd $( brew --prefix )/Homebrew/Library/Taps/homebrew/homebrew-core
git checkout 9ba3d6ef8891e5c15dbdc9333f857b13711d4e97 Formula/[email protected]
brew install [email protected]
echo 'export PATH="$(brew --prefix [email protected])/bin:$PATH"' >> ~/.bashrc

I have OS X El Capitan system. I tracked on this link :

https://github.com/thoughtbot/capybara-webkit/wiki/Installing-Qt-and-compiling-capybara-webkit

then

gem install capybara-webkit -- --with-opt-include=/usr/local/bin/qmake

This problem has been solved.

Answer 5

I had to run:

QMAKE="$(brew --prefix [email protected])/bin/qmake" gem install capybara-webkit

in order to get the gem to install after I got Error: [email protected]: unknown version :mountain_lion and followed the commenting step from the Homebrew instructions:

NOTE: If you get Error: [email protected]: unknown version :mountain_lion, comment line #25 in Formula/[email protected]

For AltLinux it should be done the following:

1. As of root install gem-capybara-webkit-devel package:

   # apt-get install gem-capybara-webkit-devel
   

2. export the PATH's additionals required for the compilation:

   $ export PATH=/usr/share/qt5/bin:$PATH
   

3. install the gem with bundler

   $ bundle
