Question

我正在尝试运行需要“capybara-webkit”宝石的Rails应用程序。我已经安装了0.12.1版但是应用程序要求0.10.1。我无法让它工作，即使我确信其他一切都已安装。我想知道路径或Qt版本是不兼容还是不正确？

当我尝试安装gem时，我收到以下错误消息：

错误：（gem install capybara-webkit -v'0.10.1'）

   Installing capybara-webkit (0.10.1) with native extensions 
 Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

     C:/RUBY/RailsInstaller/Ruby1.9.3/bin/ruby.exe extconf.rb 


 Gem files will remain installed in 

 C:/RUBY/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/capybara-webkit-0.10.1 for 

 inspection.
 Results logged to C:/RUBY/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/capybara-

 webkit-0.10.1/./gem_make.out

gem_make.out：

   C:/RUBY/RailsInstaller/Ruby1.9.3/bin/ruby.exe extconf.rb

extconf.rb：

   require File.join(File.expand_path(File.dirname(__FILE__)), "lib","capybara_webkit_builder")
 CapybaraWebkitBuilder.build_all

我确信我安装了正确的软件（如下所示）。

Answer 1

确保已安装Qt v4.7.4 w/ support for mingw32并将Qt的bin目录添加到PATH。在安装期间，当询问MinGW路径时，请选择Ruby193\devkit\mingw目录。

之前我遇到过同样的问题，这是我找到的最快的解决方案。

较新版本的Qt仍然存在与Windows的兼容性问题。但是，如果您决定尝试一下，请查看Error while building native extensions for capybara-webkit。

Answer 2

您尚未向环境添加mingw路径，因此构建过程无法正常工作。您必须遵循https://github.com/thoughtbot/capybara-webkit/wiki/Installing-Qt-and-compiling-capybara-webkit并正确获取所有依赖项版本。

无法在Windows中安装Rails Gem capybara-webkit
