Cannot mix incompatible Qt library (version 0x50501) with this library (version 0x50201)

I have installed Shadowsocks-Qt5 within the code sudo apt-get install shadowsocks-qt5 in terminal, and then I can find the launch icon by searching, but it won't open when I click the icon. Then I tried to use terminal to open it, but the error comes out as below:

~ ss-qt5Cannot mix incompatible Qt library (version 0x50501) with this library (version 0x50201)[1]    8875 abort (core dumped)  ss-qt5

I searched many answers but no one work. I think the key may be the default Qt library, but I don't know how to set default Qt library, the system on my computer is Ubuntu 14.04 LTS.

How to solve this problem?
