分析原因

在https://bitbucket.org/kmgreen2/pyeclib找到如下的解释：

If the test suite fails because it cannot find any of the shared libraries, then you probably need to add /usr/local/lib to the path searched when loading libraries. The best way to do this (on Linux) is to add ‘/usr/local/lib’ to:
/etc/ld.so.conf
and then make sure to run:
$ sudo ldconfig

解决办法

出现错误的原因是找不到共享库，需要添加/usr/local/lib到环境中加载库，最好的解决办法是将/usr/local/lib添加到：
/etc/ld.so.conf文件中（include /usr/local/lib），接着运行下面的命令：
$ sudo ldconfig。

再次执行，问题解决：
