3.1 终端输入qtcreator提示

Already tracking action "Follow Symbol Under Cursor" under id 173
Cannot start '/usr/lib/x86_64-linux-gnu/qt4/bin/qmake': No such file or directory错误

安装完成后一般还要修改一些配置。

在命令行中输入：sudo vi /usr/lib/x86_64-linux-gnu/qt-default/qtchooser/default.conf

打开default.conf文件，

将第一行改为bin目录的路径，第二行改为qt5.8.0目录的路径。

之后输入qmake -v可以得到正确的version。

4. 設置命令行参数
