El Capitan:无法安装capybara-webkit

Question

我无法bundle，因为在安装capybara-webkit (1.11.1)时发生错误。所以我尝试了gem install capybara-webkit -v '1.11.1'，但它返回了错误：Failed to build gem native extension.我甚至不确定它是什么意思。

整个输出将是：

Building native extensions.  This could take a while...
ERROR:  Error installing capybara-webkit:
    ERROR: Failed to build gem native extension.

    current directory: ...

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may

Gem files will remain installed in .../capybara-webkit-1.11.1 for inspection.

有人知道如何处理这个问题吗？提前谢谢你！

Answer 1

@raghu发布的答案将与Qt5.5一起工作，Qt5.5是由capybara-webkit的开发者官方支持的最后一个版本。另一种选择是让homebrew使用当前版本的qt安装qt-webkit，然后在此基础上构建capybara-webkit。首先从homebrew卸载qt，如果你已经安装了它(brew uninstall qt)，然后

brew install qt --with-qtwebkit

然后去做点别的事情，因为它是从源代码编译过来的。完成后，尝试再次安装capybara-webkit gem。

Answer 2

试试这个：

brew install qt@5.5
brew link --force qt@5.5
gem install capybara-webkit
