今天一同事发过来一个报错信息，提示如下：
error while loading shared libraries: libQt5Widgets.so.5: cannot open shared object file: No such file or directory
查了几个博客分享的解决方法，装了一些包（例如 libGL libGL-devel）等无果，后来发现了一个 rpm 包的网站 rpm.pbone.net，然后安装了一个线上rpm包；
开始提示说有依赖：
[root@log ~]# rpm -ivh ftp://mirror.switch.ch/pool/4/mirror/centos/7.4.1708/os/x86_64/Packages/qt5-qtbase-gui-5.6.2-1.el7.x86_64.rpm
获取ftp://mirror.switch.ch/pool/4/mirror/centos/7.4.1708/os/x86_64/Packages/qt5-qtbase-gui-5.6.2-1.el7.x86_64.rpm
错误：依赖检测失败：

qt5-qtbase(x86-64) = 5.6.2-1.el7 被 qt5-qtbase-gui-5.6.2-1.el7.x86_64 需要

然后我安装了 qt5-qtbase
[root@log ~]# yum install -y qt5-qtbase
安装完成后，再执行上条rpm安装时，就OK了
[root@log ~]# rpm -ivh ftp://mirror.switch.ch/pool/4/mirror/centos/7.4.1708/os/x86_64/Packages/qt5-qtbase-gui-5.6.2-1.el7.x86_64.rpm
获取ftp://mirror.switch.ch/pool/4/mirror/centos/7.4.1708/os/x86_64/Packages/qt5-qtbase-gui-5.6.2-1.el7.x86_64.rpm
准备中... ################################# [100%]
正在升级/安装...
1:qt5-qtbase-gui-5.6.2-1.el7 ################################# [100%]

之后再执行命令就不报错了，
[root@log ~]# /home/arith/sources/PredictConsole

今天安装的时候出现了不一样的问题。
[root@iZwz9chwdyqnsgcy638aafZ ~]# rpm -ivh ftp://mirror.switch.ch/pool/4/mirror/centos/7.4.1708/os/x86_64/Packages/qt5-qtbase-gui-5.6.2-1.el7.x86_64.rpm

后来直接使用 yum install -y qt5-qtbase-gui 安装解决的。。。

具体分析待后续类似情况跟进..
