安装matspotlib报错

risepp

环境是redhat6.2 64位，python2.7.5
直接通过pip install matsplotlib，报错如下：（我尝试使用源码通过python setup.py install安装也报同样的错误）
Edit setup.cfg to change the build options

有兄弟遇到类似问题么？怎么解决的啊？望告知，多谢

该问题已经解决了，我把我本机windows环境上python2.7下site-package所有文件upload到redhat环境中，再安装就顺利完成了，但是执行命令时报了另外一个错误：

ImportError: libpng16.so.16: cannot open shared object file: No such file or directory

我核查了一下环境，libpng已经安装了（通过源码编译安装的），且该文件存在
[root@master /]# find . -name "libpng16.so.16"
./tmp/libpng-1.6.18/.libs/libpng16.so.16
./usr/local/lib/libpng16.so.16

是因为lib的路径配置有问题么？

icymirror

可以先查看下 sys.path 有哪些。

risepp

sys.path不包含这个路径，我设置了PYTHONPATH环境变量后，再运行IPYTHON=1 IPYTHON_OPTS="--pylab" ./bin/pyspark依然报同样的错误，唉
进去shell里面再check变量，值已经添加了
