CentOS7 python安装ta_lib

1.下载ta_lib依赖包

从https://sourceforge.net/projects/ta-lib/files/ta-lib/0.4.0/下载依赖包，对于Windows需要安装msvc包，对64位linux需要下载ta-lib-0.4.0-src.tar.gz源码自己编译。先下载源码

wget https://downloads.sourceforge.net/project/ta-lib/ta-lib/0.4.0/ta-lib-0.4.0-src.tar.gz?r=https%3A%2F%2Fsourceforge.net%2Fprojects%2Fta-lib%2Ffiles%2Fta-lib%2F0.4.0%2F&ts=1509527628&use_mirror=nchc

使用root用户解压并编译安装

#tar -xvf ta-lib-0.4.0-src.tar.gz
#cd ta-lib
#./configure 
#make && make install 

默认的ta_lib的c程序库被包含到/usr/local/lib里面了，系统可能不能找到，需要配置一下：

#echo "/usr/local/lib" >> /etc/ld.so.conf
#ldconfig

如果不配置可能报错：

>>> import talib
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/python3/lib/python3.5/site-packages/talib/__init__.py", line 4, in <module>
    from . import common
ImportError: libta_lib.so.0: cannot open shared object file: No such file or directory

2.安装python的ta_lib wrapper

pip3 install TA-Lib

如果不安装前面的ta_lib包，会报错：fatal error: ta-lib/ta_libc.h: No such file or directory compilation terminated.
