linux下安装Qt5.7后添加qmake环境变量后出现错误 

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/qtchooservim

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 ）
