执行
qmake
-v

出现错误：qmake: could not exec ‘/usr/lib/x86_64-linux-gnu/qt4/bin/qmake’: No such file or directory
分析：
qtchooser默认选择路径中没有指向qmake路径
解决方法：
cd
/usr/lib/x86_64-linux-gnu/qt-
default
/qtchooser
vim
default
.conf

将第一行中的/usr/lib/x86_64-linux-gnu/qt4/bin/qmake
替代为qmake的路径（我的安装路径/home/yqa1404/Qt5.9.3/5.9.3/gcc_64/bin ）
