Failed building wheel for scrypt

[ghost]

Windows 10 64 Fresh install using Anaconda Python 3.6.3 |Anaconda, Inc.| (default, Oct 15 2017, 03:27:45) [MSC v.1900 64 bit (AMD64)] on win32

I have installed C++ Visual Studio

But I keep getting an error for scrypt :

I had a similar problem when installing the steem-python package on Windows. From the errors, I think you are missing some header files for building this package. Try installing python3-dev through pip3.

I met the same error. I created and edited a unistd.h file.Then it told me that I need a "sys/time.h"file.

I got a compiled wheel from here,and changed the name for my environment python36.Now i can import steem.

You can install scrypt from sources via

$ hg clone http://bitbucket.org/mhallin/py-scrypt
$ cd py-scrypt
$ PATHTOPYTHON3 setup.py build

You need to open setup.py and change lines:

    if struct.calcsize('P') == 8:
        library_dirs = ['c:\OpenSSL-Win64\lib']
        includes = ['c:\OpenSSL-Win64\include', 'scrypt-windows-stubs/include']
    else:
        library_dirs = ['c:\OpenSSL-Win32\lib']
        includes = ['c:\OpenSSL-Win32\include', 'scrypt-windows-stubs/include']

to your OpenSSL libraries. You can use libraries from here: https://slproweb.com/products/Win32OpenSSL.html (you need to use version <1.1.0, because of names of lib files are changed in it, latest correct version - Win32 OpenSSL v1.0.2n)

Can set to resolved. I release py-scrypt 0.8.3, which includes wheels for python 3.6. Read more here: https://steemit.com/utopian-io/@holger80/py-scrypt-0-8-3-released

You can try my conda-forge version: https://github.com/conda-forge/steem-feedstock https://utopian.io/utopian-io/@holger80/install-steem-python-easily-by-conda-forge

Fixed it today by issuing apt-get install libssl-dev apt-get install openssl

This is an environment issue, not an issue with the library. Closing.
