推荐答案
您应检查LD_LIBRARY_PATH环境变量并检查您的libpng是否在其中。
You should check your LD_LIBRARY_PATH environnment variable and check that your libpng is in it.
python报告的问题是动态加载的问题：matplotlib的重新编译没什么可看的。
The problem reported by python is a problem of dynamic loading : Nothing to see with the recompilation of matplotlib.
所以：
-
找到libpng.14.so的位置：
Find the location of libpng.14.so with :
$> locate libpng.14.so
$> locate libpng.14.so
请注意，该文件必须具有确切的名称，因此您可能必须创建符号链接，例如，如果您有libpng.14 .so.0或类似的东西（通常在安装lib时自动创建符号链接
Note that the file must have the exact name so you may have to create a symbolic link if for example you have libpng.14.so.0 or something like that (Usually the symbolic links are automatically created when you install your lib
如果你没有任何libpng.14.so.som ething或libpng.14.so，您可能需要重新安装libpng 1.4（使用您的软件包管理器或直接从源代码管理器）
If you don't have any libpng.14.so.something or libpng.14.so, you may need to reinstall libpng 1.4 (with your package manager or directly from the sources)
检查$ LD_LIBRARY_PATH。如果需要，可以更改它：
Check $LD_LIBRARY_PATH. Change it if you need with :
$> export LD_LIBRARY_PATH = anewDir：$ LD_LIBRARY_PATH
$> export LD_LIBRARY_PATH=anewDir:$LD_LIBRARY_PATH
