Mac下brew安裝和配置Qt5的坑與解決辦法

1. 安裝PyQt5:

brew install qt
brew cask install qt-creator

2 然後在 Qt Creator 裏改一下 Qt Versions的坑: 參考知乎boyu的回答

    2.1 偏好設置-Kits-Qt Versions-添加路徑/usr/local/Cellar/qt/5.11.2/bin/qmake

        

    2.2 偏好設置-Kits-構建套件(Kit)-手動設置-桌面(默認)-Qt版本-Qt 5.11.2

        

3 創建項目(Project)的坑: 參考《QT Creator 兩種創建項目的方法》

    方法之一：
    先建項目：歡迎-New Project-其他項目-Empty qmake Project => 一路默認就建好了一個項目了
    再添加CPP文件：在項目上右鍵-Add  New...-C++-C++源文件 => 一路默認，如果報錯解決方法如下：

    3.1 報錯：解決辦法參考《Mac下用brew配置QT開發環境》

Project ERROR: failed to parse default search paths from compiler output
Error while parsing file /Users/hanpeizhi/Qt5/testProject01/testProject01.pro. Giving up.

        把編譯器C和C++全部改爲Clang

         

    3.2 報錯：解決辦法參考知乎boyu回答中的評論

Project WARNING: Qt has only been tested with version 10.13 of the platform SDK, you're using 10.13.4.
Project WARNING: This is an unsupported configuration. You may experience build issues, and by using
Project WARNING: the 10.13.4 SDK you are opting in to new features that Qt has not been prepared for.
Project WARNING: Please downgrade the SDK you use to build your app to version 10.13, or configure
Project WARNING: with CONFIG+=sdk_no_version_check when running qmake to silence this warning.

        打開終端輸入命令: 

xcode-select -p

        因爲我已經安裝了Xcode了，所以直接在輸入（如果還沒安裝就先去App Store安裝）：

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

        如下：

$ xcode-select -p
/Library/Developer/CommandLineTools

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

目前我就遇到這些坑，所以就寫這麼多。
另外安裝和配置PyQt5參考：《Mac下Pycharm集成PyQt5並使用》
