初学银河麒麟linux笔记 第三章 QT缺少的模块下载、更新软件源操作
在共享文件夹里将WINDOWS里已经编写好的QT程序编译之后，提示
Qt5: Unknown module(s) in QT: serialport
经查询，需要安装对应的模块库，写入
sudo apt-get install libqt5serialport5-dev libudev-dev
但命令端提示
“无法定位软件包”
经查询，是软件源需要进行更新，国内比较常用的是清华的软件源
首先
sudo cp /etc/apt/sources.list /etc/apt/sources.list.old //先把源文件复制到sources.list.old
然后对etc/apt/里的sources.list进行修改，我这里由于一直设置的只读，因此采用的vim修改，即
cd /etc/apt/
sudo vim sources.list
弹出编辑页面，将软件源复制进去
我这里采用的是
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://archive.kylinos.cn/kylin/KYLIN-ALL 4.0.2sp2-desktop main restricted universe multiverse
注意：银河麒麟系统里每个“https”都要改为“http”，否则识别不出。当地址变红说明格式正确
改完后，按esc按钮，再按":"可输入执行指令，按回车键结束
一般是采用“w”保存，“q”退出。由于我的文件是只读且权限是root，因此采用了
:w !sudo tee %
进行保存。
退出修改界面后，可在窗口上查看文件是否发生变化
确定修改完毕后，保持联网状态，输入
sudo apt-get update
可能会出现这个问题
E: 无法获得锁 /var/lib/apt/lists/lock - open (11: 资源暂时不可用)
E: 无法对目录 /var/lib/apt/lists/ 加锁
这时进行解锁
sudo rm /var/lib/apt/lists/lock
然后再进行更新
sudo apt-get update
一般就没问题了
等待软件源更新完毕之后，再安装对应的模块库
sudo apt-get install libqt5serialport5-dev libudev-dev
安装完毕后编译qt，模块已成功下载，该问题已解决。
下面是ＱＴ依赖的所有的库，构建运行过程中缺少哪一个库，找到后执行sudo apt-get install＋库
