Cannot install scypt on python2.7

Question

I could not get pip install scrypt to work, after reading a round a bit I tried installing Visual Studio 2017, that did not work, then I tried to following the example from Windows Compilers

MinGW-w64 is an alternative C/C++ compiler that works with all Python versions up to 3.4.

Install Win-builds into C:\MinGW_w64.

Open Win-builds, switch to install at least binutils, gcc, gcc-g++, getext, mingw-w64, win-iconv, winpthreads, zlib, and click Process.

Add C:\MinGW_w64\bin to the PATH environment variable.

Create a distutils.cfg file with the following contents in the folder \Lib\distutils in Python install directory : 

[build] compiler=mingw32

[build_ext] compiler=mingw32

That produced this new error,

Anyone have any ideas as to what I should do next, I am somewhat lost.

EDIT

I have tried Arnav Poddar suggestion, I got:

Not sure if I did it right. I have a result to long to post here but the errors for python setup.py build were:

It defaults the other error message of REEE! "Use this header only with Microsoft Visual C++ compilers!" when I 'reinstall' disutils.cfg. This blows, I had all of these libraries already installed on a system that is about 6 years old, it blew up and I just got the parts to build a new one. I know it can install, I just don't remember how I pulled it off.

Answer 1

I recommend trying python -m easy_install scrypt . In the past, whenever I get an error of failed with error code 1 , I use easy_install instead of pip , and it works perfectly.

Answer 2

pip install scrypt==0.8.11 :)

Above that .11 will also show a bunch of errors like that.

install Win64OpenSSL-1_1_1c.msi..

I have recieved an error like that when I installed keypatch for ida 7
