When I tried to
import matplotlib.pyplot as plt
I was given the following error:

Can anyone please help me? I'm a newbie and not really familiar with paths. A step-by-step instruction would be greatly appreciated. Thanks in advance.
BTW, I'm using spyder as an IDE.
as presented here: https://askubuntu.com/questions/636937/python-2-7-matplotlib-provides-errorpyplot
this command will fix it: conda install matplotlib
and indeed it helped me.
It's likely your library path is not set up correctly, and doesn't point to wherever the file libpng15.15.dylib
is located.
Since this file should probably come with the anaconda installation (provided this is how you have installed Python and matplotlib), check if you can find this file in /Users/Zhangnan/anaconda/lib/
.
If you find that file there, set your LD_LIBRARY_PATH
:
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/Users/Zhangnan/anaconda/lib/
You may also want to add that line to your ${HOME}/.bashrc
file.
我使用Kali Linux,我使用:pip install matplotlib
