在Fedora上安装Capybara-webkit

Question

所以我在Fedora 17上尝试安装Capybara Webkit。 我按照这里的指示进行操作，并为该项目的另一个（近乎相同）分支安装了软件包，因此我知道它可以工作。

当我尝试bundle install ，出现此错误。 任何人都有想法，还是我应该与co一起记录错误？

Installing capybara-webkit (0.12.1)

安装capybara-webkit（0.12.1）时发生错误，并且Bundler无法继续。 捆绑之前，请确保gem install capybara-webkit -v '0.12.1'成功。

Answer 1

版本0.12.1是gem的过时版本-我为以前的项目安装了类似版本时遇到很多麻烦。

我建议升级到较新的版本-依赖项将更新，并且安装将减少很多麻烦。

capybara-webkit依赖于Qt的WebKit实现，Qt是跨平台开发工具包。 您需要下载Qt库以构建和安装gem。 下载和安装QT的说明： https : //github.com/thoughtbot/capybara-webkit/wiki/Installing-Qt-and-compiling-capybara-webkit
