alembic-script unquoted executable path causes failure to run on windows.

Migrated issue, originally created by khazhyk (khazhyk)

I'm on Windows 10.

I noticed that when installing alembic through pip (version 0.8.4 as of now), when trying to run the 'alembic' command I got an error 'failed to create process.'

^ for anyone googling.

In alembic-script.py the first line is as such when it is installed:
#!c:\program files (x86)\python35-32\python.exe

This results in trying to invoke "C:\program" as the python interpreter. When the path is quoted and the line is changed to
#!"c:\program files (x86)\python35-32\python.exe"

Alembic functions as expected.

hi there -

unfortunately this is a bug in pip itself; see pypa/pip#2783 for details as well as workarounds.
