安装qt遇到的问题

1 undefined reference to `JSC::Yarr::nondigitsCreate()’

未安装python库，或者python库环境未配置好

2 Project ERROR: Unknown module(s) in QT: quick

apt-get install qtdeclarative5-dev

3 systemctl: command not found

apt-get install --reinstall systemd

4 The test for linking against libxcb and support libraries failed!

sudo apt-get install libxcb* 

5 qmake: could not find a Qt installation of ‘’

1. 删除原先的链接： sudo rm /usr/bin/qmake
2. 建立新的链接： sudo ln -s 你的Qt qmake 的位置 /usr/bin/qmake 即可，例如，我的 Qt qmake 的位置在 /home/Qt5.4.0/5.4/gcc_64/bin/qmake 。
