我安装matplotlib是通过当我尝试用它保存png时,我得到libpng warning: Application is running with png.c from libpng-1.2.44
libpng error: Incompatible=> /lib/x86_64-linux-gnu
最近,我从16.04升级到18.04,同时尝试启动qjack,我得到了这个错误
qjackctl: relocation error: /usr/lib/x86_64-linux-gnu/libQt5Gui.so.5: symbol png_set_option version PNG16_0 not defined in file libpng16.so.16 with link time reference因此,我尝试重新安装qjack,所有的qt5库和libpng16库都没有效
