ImportError: modules/XXX.so: undefined symbol: PyUnicodeUCS2_DecodeUTF8

问题:
服务器Linux系统原生python2.7.9, 想升级运行多进程multiprocessing【见此链接】。 想使用Anaconda2安装python2.7.15, 安装完成后,导入编译好的.so文件遇到问题:
ImportError: modules/XXX.so: undefined symbol: PyUnicodeUCS2_DecodeUTF8

Google之:
系统原生的python为UCS2编码,Anaconda的 python均为UCS4, .so文件编译时的平台为UCS2

"on Linux all Anaconda Python packages use UCS4, more precisely: Because Anaconda Python 2 itself was compiled using the UCS4 flag, all (C extension) packages build against it, will be only compatible with a UCS4 Python 2 build. In many Linux distributions, e.g. Ubuntu, CentOS, UCS4 is used by the system Python (/usr/bin/python). You can always check this by looking at sys.maxunicode: the value 1114111 means UCS4 and 65535 means UCS2. It would be a large effort to provide an additional version of Anaconda for Linux in which all packages are build against a UCS2 compiled Python 2. "

我的解决方案:
卸载Ananconda, 手动下载并安装Python 2.7.15.
