I'm trying to set up an environment in Windows 10 where I can program in Python 3 and utilize libraries and modules as I please. I am seemingly unable to achieve this through Cygwin.
EDIT: I have rewritten much of this question to be more relevant. From here on are better details.
Through the Cygwin installer python3, python3-devel, python3-setuptools, gcc and make is picked and installed.
I have installed(and made sure is not interfering with non-Cygwin python) pip/pip3 and am trying to install numpy. This is the error I get from running $ pip3 install numpy:
(Both $ python3 and $ easy_install-3.6 are working and isolated from "normal" python, although $ easy_install-3.6 gives the same errors as $ pip3)
$ pip3 install numpy

gcc: command not found– you need to install basic build tools in Cygwin first. Have you installed a "normal" Windows Python as well? – slhck – 2017-07-12T19:23:34.197@slhck I believe so. I find a python3 installation at
D:\Users\USERNAME\AppData\Local\Programs\Python\Python36-32How can I "install basic build tools"? Shouldn't dependencies install themselves? – Loke Gustafsson – 2017-07-12T19:51:03.587Additionally,
C:\Users\USERNAME\AppData\Roaming\Python\Python27\site-packagesdoesn't exist. – Loke Gustafsson – 2017-07-12T19:55:24.7532You are mixing cygwin python installation with one that is windows only.
D:\Users\USERNAME\AppData\Local\Programs\Python\Python36-32is not cygwin one. – matzeri – 2017-07-12T20:30:31.503Either use the Windows Python or the Cygwin Python. Make sure that
pythonandpipandeasy_installetc. point to the Cygwin version if you prefer the latter. Also, you need to (at least) installgccandmakethrough the Cygwin installer. – slhck – 2017-07-13T07:29:38.007Both "normal" python-2.7 and cygwin's python-3.6 are installed on my computer. Apparently
easy_install,pipandpip3were all connected to my python-2.7 installation. I could removepip3from my python-2.7 installation and install another version of pip througheasy_install-3.6(which is connected to python inside cygwin). – Loke Gustafsson – 2017-07-13T11:34:03.633Despite all of this, I still get the very same error message when I run
$ pip3 install numpy. I installed bothgccandmakethrough the Cygwin installer, but I still get the same error message. – Loke Gustafsson – 2017-07-13T11:39:03.810Any reason to not use
python3-numpypackage already available ? – matzeri – 2017-07-13T16:13:54.717I hadn't thought about
python3-numpy, but I still lack the ability to install modules not available through Cygwin. I tried this and fair enough,$ pipsays that it works. However, when importing numpy in actual python code I receive an error about missing dependencies. (from . import multiarray --> ImportError: No such file or directory, this is inside numpy code) Sadly, this doesn't solve the problem with the missing dependencies that I can't figure out. – Loke Gustafsson – 2017-07-13T20:47:51.923After reading up on what that
.means, supposedly am I missing a filemultiarray.pyfromsite-packages\numpy\core. Is this correct? Although I do have a file calledmultiarray.cpython-36m-x86_64-cygwin.dllthere. – Loke Gustafsson – 2017-07-13T20:53:09.127
