Mac OS 10.14 Mojave + qt5.5 + gem capybara-webkit

Question

我的配置是MAC Mojave v10.14.

我尝试安装需要qt5.5的宝石Capybara-webkit -v'1.15.0',但是自制的qt5.5已被删除,并且它与Xcode v10不兼容.

我试试这个:

• 卸载Xcode v10
• 安装在developer.apple.com/中的Xcode 9.4.1
• 安装qt5.5,我在qt.io/的档案中找到了它
• 运行包

但它失败了,我的错误是宝石capybara-webkit -v'1.15.0':

接下来,我做了:

sudo xcodebuild -license agree

但错误仍然存​​在......

谢谢您的帮助 !

如capybara-webkit wiki所述,capybara-webkit取决于Qt 5.5."Qt 5.5是capybara-webkit将支持的Qt的最后一个版本.Qt项目已经从5.6中的二进制版本中删除了WebKit绑定."

要安装Qt 5.5,请按照wiki的说明进行操作.对于Mojave,说明如下.

brew update
cd $( brew --prefix )/Homebrew/Library/Taps/homebrew/homebrew-core
git checkout 9ba3d6ef8891e5c15dbdc9333f857b13711d4e97 Formula/qt@5.5.rb
brew install qt@5.5
echo 'export PATH="$(brew --prefix qt@5.5)/bin:$PATH"' >> ~/.bashrc

您可以通过运行确认此步骤:

$ which qmake
/usr/local/opt/qt@5.5/bin/qmake

接下来,您需要安装Xcode 9.4.Xcode 10与Qt 5.5不兼容.Xcode 9.4可以从Apple开发人员门户下载.这是一个4GB的下载,下载和安装大约需要30分钟.您可以通过运行以下命令来验证它是否已正确安装:

$ /usr/bin/xcodebuild -version
Xcode 9.4.1
Build version 9F2000

如果这不起作用,可能是因为您只安装了命令行工具而不是Xcode,在这种情况下,您应该确保下载了正确版本的Xcode.或者Xcode文件夹可能设置不正确.如果是这样,你可以使用修复它xcode-select,它将指定xcodebuild运行的文件夹:

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

最终安装Xcode时,在"应用程序"文件夹中找到它,打开它并同意许可证.然后尝试重新安装capybara-webkit.

免责声明:我从编译多个问题和答案中得出了上述答案,并试图记住我在本地计算机上运行命令的顺序.我可能不小心省略了一些步骤.

这是对我有用的方法，在这里找到：

• 保持你的 xcode v10 安装
• 从他们的网站手动下载并安装 Qt 5.5
• PATH通过将此添加到您的环境变量中，将Qt 的 bin 路径添加到您的环境变量中.bashrc，.zshrc或任何其他的shell配置，你必须：（请务必将/Applications/Qt/5.5/clang_64/bin你的Qt的bin路径）

export PATH="/Applications/Qt/5.5/clang_64/bin:$PATH" # Add Qt bin to path for capybara webkit to work

• 跑 gem install capybara-webkit
