Installing gmpy2 on windows using pre-compiled binaries

Question

I am trying to install the gmpy2 package as its an requirement for the PHE package. As suggested in "GMPY2 not installing", I have tried to install it via pre-compliled binaries from http://www.lfd.uci.edu/~gohlke/pythonlibs/.

However when I try to install it via

pip install gmpy2-2.0.8-cp36-cp36m-win32.whl

I get the following result:

C:\Users\adria\Desktop>pip install gmpy2-2.0.8-cp36-cp36m-win32.whl

Requirement 'gmpy2-2.0.8-cp36-cp36m-win32.whl' looks like a filename, but the file does not exist

Processing c:\users\adria\desktop\gmpy2-2.0.8-cp36-cp36m-win32.whl Exception: Traceback (most recent call last): (...)

Is it a problem that the download from http://www.lfd.uci.edu/~gohlke/pythonlibs/ is saved as zip file?

I use Python 3.6.3 on Win10.

Indeed, you must unzip the .zip file, and run `pip install gmpy2-2.0.8-cp36-cp36m-win32.whl` inside the directory holding the file — bobolafrite, Oct 31 '17 at 13:03
The unzip file is an .pyd file. Im just unable to get this whl file. — ARedder, Oct 31 '17 at 13:43
Download it from this link : https://www.lfd.uci.edu/~gohlke/pythonlibs/#gmpy — bobolafrite, Oct 31 '17 at 13:53
I know. But the result is a zip file, but I think I need to convert it into a whl file to install it in this way, but I don't know how. Thanks and sorry I am quite new. — ARedder, Oct 31 '17 at 14:00

If you try to install without specifying the file extension (i,e : pip install gmpy2-2.0.8-cp36-cp36m-win_amd64) it won't work cause it will try to download the package from pypi repository:

C:\Users\bobolafrite\Downloads>pip install gmpy2-2.0.8-cp36-cp36m-win_amd64

Collecting gmpy2-2.0.8-cp36-cp36m-win_amd64
    Could not find a version that satisfies the requirement gmpy2-2.0.8-cp36-cp36m-win_amd64 (from versions: )
    No matching distribution found for gmpy2-2.0.8-cp36-cp36m-win_amd64

But if you try with the extension (i,e : pip install gmpy2-2.0.8-cp36-cp36m-win_amd64.whl)

C:\Users\bobolafrite\Downloads>pip install gmpy2-2.0.8-cp36-cp36m-win_amd64.whl

Processing c:\users\bobolafrite\downloads\gmpy2-2.0.8-cp36-cp36m-win_amd64.whl

Thank you so far. Using: C:\Users\adria\Desktop>pip install : gmpy2-2.0.8-cp36-cp36m-win32.whl Results in: Invalid requirement: ':' Traceback (most recent call last): ... – ARedder Oct 31 '17 at 10:48
Whoops sorry don't know why I typed this ":" . It should never appear in a pip command. I edited my post – bobolafrite Oct 31 '17 at 10:53
Thanks @bobolafrite. I wasted an hour trying to install gimpy2 for Python3 and this worked a treat. btw I needed to use pip3 in place of pip. – riemannzz Jul 15 '19 at 11:16
