安装qt qmake assistant 错误：could not find a Qt installation of ‘‘

1、执行qmake,提示下图的错误

Command 'qmake' not found, but can be installed with:

sudo apt install qtchooser

解决方法：

sudo apt install qtchooser

 2、执行qmake,提示一下错误

qmake: could not find a Qt installation of ''

解决步骤：

步骤一：找到qmke命令链接路径

which qmake

 具体操作

cxx@cxx-virtual-machine:~/Demo/qBreakpad-master$ which qmake
/usr/bin/qmake

步骤二：删除连接

sudo rm /usr/bin/qmake

具体操作

cxx@cxx-virtual-machine:~/Demo/qBreakpad-master$ sudo rm /usr/bin/qmake

步骤三：重新链接【这里我安装的qt,在/opt/Qt5.14.2,所以qmake路径就是/opt/Qt5.14.2/5.14.2/gcc_64/bin/qmake】

sudo ln -s /opt/Qt5.14.2/5.14.2/gcc_64/bin/qmake /usr/bin/qmake
