Question

我无法bundle，因为安装capybara-webkit (1.11.1)时出错了。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.

有谁知道如何处理这个问题？提前谢谢！

试试这个：

Answer 2

@raghu发布的答案将与Qt5.5一起使用，这是capybara-webkit开发人员正式支持的最后一个版本。另一种选择是使用当前版本的qt制作自制软件安装qt-webkit，然后针对该版本构建capybara-webkit。如果您已经安装了qt，请从自制软件中卸载qt（brew uninstall qt），然后

brew install qt --with-qtwebkit

并且从源头开始编译并暂时执行其他操作。一旦完成，请再次尝试安装capybara-webkit gem。
