El Capitan：无法安装 capybara-webkit

Question

我无法 bundle，因为安装 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. 我什至不确定这是什么意思。

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？提前致谢！

Answer 1

试试这个：

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

Answer 2

@raghu 发布的答案将适用于 Qt5.5，这是 capybara-webkit 开发人员正式支持的最后一个版本。另一种选择是让自制软件使用当前版本的 qt 安装 qt-webkit，然后针对它构建 capybara-webkit。如果您已经安装了 qt (brew uninstall qt)，请先从 homebrew 中卸载它，然后

brew install qt --with-qtwebkit

然后在从源代码编译时去做一些其他的事情。完成后再次尝试安装 capybara-webkit gem。
