#102729 — Cygwin and Python3

Hi, I am having a hard time making my Cygwin run Python 3.5 (or Python 2.7 for that matter).
The command will hang and nothing happens.

A cursory search on the net reveals many possibilities, which might mean a lot
of trial and error, which I would very much like to avoid.

Any suggestions on how I can get cygwin and Python3.5 to play together like brother and sister?

thanks

When you run the cygwin installer you have the option of installing 2.7 and 3.2.5, by default it will install 2.7 and 3.2 together. After running the installer run whereis python and use the alternatives to change it or use python3 instead of python #!/usr/bin/python3

Hope this helps.

I see. I was trying to do it the Perl way. I simply linked the 
strawberry perl.exe from cygwin environemnt and it replaced the built in 
perl that sucked.
OK. Backtrack. I'll try with a purely cygwin solution...

Thank you

Just curious...

Since Python runs natively in Windows, why are you trying to run it with Cygwin?
I'm not implying that you shouldn't, just offhand I don't see a reason for it.

I have now, but I'm perfectly happy with the free versions of Visual Studio.

I was referring to the procedure in general, and what looked like an 
important step to include.

So it looks like the terminal can find ssh and git, but not python. 
That's understandable, since we didn't use Cygwin to install Python. To 
tell Cygwin how to find Python, run the following command:
$ echo "PATH=\$PATH:/cygdrive/c/Python32" >> .bash_profile

I don't see any references to VS on that page so I don't know what 
you're referring to.

I suspect that Mark is reacting indirectly to the misleading implication
on that page that it is necessary to install Cygwin if you want to
develop Python code on Windows.

Thanks for explaining, I had no idea what that comment might be based on.

I do it because it's easier to install third party packages, those that
need an external library to run. Cygwin come with a lot of lib* and
lib*-devel that permit to just run `pip install xxx' if not already
packaged. I gave a try on the native Windows version and Anaconda but
there is at least one package that I could not run (and I loosed
a lot of time to compile a bunch of libraries).

Example of package: pyproj (proj4), openpyxl with lxml (libxml2,
libxslt) and pillow (libjpeg, zlib, libtiff, ...), psycopg2 (libpq).

I belive these are all available at

This thread also seems to address windows lack of support with linux. Only if windows had a linux command line support instead of using power shell. Mac is not preferred OS and its just a matter of time since windows is obsolete.
