没装qmake而已。sudo apt install -y qt5-default

我的电脑上安装了Qt5的qmake，这里是找不到Qt4的qmake

我的电脑上安装了Qt5的qmake，这里是找不到Qt4的qmake

因为debian的qtchooser默认使用的qt版本就是qt4，所以报这个错。想使用qt5直接安装qt5-default这个包就行了，会自动改变qtchooser的版本指向

谢谢你！qmake不报错了。
我是参照帖子操作的：https://www.cnblogs.com/linuxAndMcu/p/11016322.html
现在报的错是：

请再指点一二

我使用的是PostgreSQL,这里为何总是查找mysql的驱动？

ldd /home/zuoyh/QtRelease/HT_MSS/HT_MSS

看下你的可执行程序的链接。你是不是自己链接了qt的mysql插件？
打包appimage我用的是linuxdeploy，而不是linuxdeployqt，看社区说前者更好。linuxdeploy也有qt plugin，可以打包qt程序

双击HT_MSS，选择在终端中运行，给出如下提示信息：

我怎么感觉你这个qt是自己装的，而且自己装的还缺失了一部分依赖？从输出上看，你的qt应该是编译了sqldriver中的libqsqlpsql支持，但是你安装的时候你的版本又不对，这个libqsqlpsql.so像是从qt4编译的，所以符号中没有qt5的版本支持。

我用的qt一般都是通过系统软件仓库直接装的，没这些乱七八糟的问题，不知道你的qt咋装的，是不是自己编译的？那玩意坑大了去了。

另外最近在研究linuxbrew，正在给linuxbrew的qt做一些贡献，暂时也没这个问题。

我是自Qt官网下载的qt-opensource-linux-x64-5.10.1.run安装的。
我卸载它再通过系统软件仓库安装试试

使用命令安装Qt5:
$sudo apt install qtcreator qt5-default
安装完成后，发现缺少PostgreSQL驱动so包，手工拷入后运行程序出错：
/home/zuoyh/QtWork/HT_MSS/build-HT_MSS-unknown-Release/HT_MSS: relocation error: /usr/lib/x86_64-linux-gnu/qt5/plugins/sqldrivers/libqsqlpsql.so: symbol _ZdlPvm version Qt_5 not defined in file libQt5Core.so.5 with link time reference

使用系统软件仓库安装的Qt5对应的LD_LIBRARY_PATH如何设置？我找不到gcc_64所在路径
export LD_LIBRARY_PATH=/home/zlkj/technology/5.9.7/gcc_64/libLD_LIBRARY_PATH这句如何改？

不改啊，什么都不用改。

如果用的软件仓库安装的qt，所有的编译配置都是按照系统规范默认路径配备的，理论上你这些乱七八糟的环境变量都不需要配置。
另外我也不是qt的开发者，对qt不熟，你可以找deepin的开发者问问，deepin的程序基本都是qt开发的

多谢了！

哪位deepin开发者能帮我远程处理一下？

自深度软件仓库中将PostgreSQL的Qt5插件安装后运行程序就不再报错了！
