Failing on install talib in windows 7


I'm trying to install TALib in Windows, but I'm getting this error:

   common.obj : error LNK2019: unresolved external symbol TA_GetUnstablePeriod referenced in function __pyx_pf_5talib_6common_8_ta_get_unstable_period

when I run:

pip install TA-Lib

I already installed Microsoft Visual C++ Compiler for Python 2.7. How can I fix this?


Solution

  • That error is mentioned in the README in the repository: GitHub Repo

    Sometimes installation will produce build errors like this:

    func.c:256:28: fatal error: ta-lib/ta_libc.h: No such file or directory
    compilation terminated.
    

    This typically means that it can't find the underlying TA-Lib library, a dependency which needs to be installed. On Windows, this could be caused by installing the 32-bit binary distribution of the underlying TA-Lib library, but trying to use it with 64-bit Python.

    Since your error log contains amd64 it might well be that the 32bit vs 64bit issue is your actual problem.

    The library is only distributed in 32-bit format (the compilation/linking dates are from 2007)

    Check issue #11, GitHub - Issue #11 for hints on how to compile it yourself.
