我正在尝试按照他们的wiki安装最新版本的capybara-webkit（1.4.1），并安装了qt5：
sudo apt-get install qt5-default libqt5webkit5-dev
但gem install capybara-webkit将始终从g ++中获得以下编译错误：
ERROR: Error installing capybara-webkit:

我在全新安装的ubuntu 14.04服务器上使用Ruby 2.1.5p273。我该如何解决这个问题？
答案 0 :(得分：3)
我必须删除qt5-default libqt5webkit5-dev并仅安装qt4。不知道为什么文档告诉你使用qt5为14.04。他是我用来解决它的命令：
sudo apt-get remove qt5-default libqt5webkit5-dev
sudo apt-get purge
sudo apt-get autoremove
sudo apt-get install libqt4-dev libqtwebkit-dev
希望这有帮助。
答案 1 :(得分：0)
这对我有用：
apt-get install g++-4.7
GCC=g++-4.7 gem install capybara-webkit -v '1.11.1'
可能是GCC 4.8的错误
