centos7 如何處理 libQt5Widgets.so.5 問題

今天一同事發過來一個報錯信息，提示以下：
error while loading shared libraries: libQt5Widgets.so.5: cannot open shared object file: No such file or directory
查了幾個博客分享的解決方法，裝了一些包（例如 libGL libGL-devel）等無果，後來發現了一個 rpm 包的網站 rpm.pbone.net，而後安裝了一個線上rpm包；
開始提示說有依賴：
[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

錯誤：依賴檢測失敗：

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

而後我安裝了 qt5-qtbase
[root@log ~]# yum install -y qt5-qtbase
安裝完成後，再執行上條rpm安裝時，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

準備中... ################################# [100%]
正在升級/安裝...
1:qt5-qtbase-gui-5.6.2-1.el7 ################################# [100%]

以後再執行命令就不報錯了，
[root@log ~]# /home/arith/sources/PredictConsole
PredictConsole v0.9, 2017
Usage:
PredictConsole inFileSale inFileWeather startPredictDay lenth outFile dir

• -inFileSale: An absolute file path of history sale data.

今天安裝的時候出現了不同的問題。
[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

error: Failed dependencies:

後來直接使用 yum install -y qt5-qtbase-gui 安裝解決的。。。

具體分析待後續相似狀況跟進..
