importerror: libpng16.so.16: cannot open shared object file: no such file or directory

I am trying to install matplotlib version 2.0.0. I don't have root access, hence can't use sudo/apt-get When I tried installing matplotlib, it showed dependencies on freetype and libpng. So, I executed the following steps:,Programs installed in a user's home directory may also install some necessary libraries. The way to tell the program loader where these libraries are is through the environment variable LD_LIBRARY_PATH.,Ask Ubuntu is a question and answer site for Ubuntu users and developers. It only takes a minute to sign up.,Which worked perfectly fine. But when I do import matplotlib.pyplot as plt it throws the following error:

export LD_LIBRARY_PATH="/$HOME/<any other optional program directories>/lib"

copy libpng16.so.16 to /usr/lib/ may be anycodings_matplotlib ok. in my computer(Fedora 19), anycodings_matplotlib libpng16.so.16 can be found in anycodings_matplotlib /usr/local/lib,I have meet the same problem with you. anycodings_matplotlib Maybe you can try copy libpng16.so.16 to anycodings_matplotlib /usr/lib64/. It works for me,I have found the file "libpng16.so.16" and anycodings_python copied it to /usr/lib. But nothing anycodings_python happened. Any help will be appreciated.,After installing matplotlib successfully on anycodings_python my Fedora19,I tested my code written by anycodings_python python. Unfortunately,I got this anycodings_python ImportError .
