As 2.7 is now out of support, I'm going to go ahead and close this issue.

I do not know what setuptools plans on with regards to distlib sorry.

[issue23121] pip.exe breaks if python 2.7.9 is installed under c:\Program Files\Python

[Joshua Ellinger]

New submission from Joshua Ellinger:

The problem is that the python path name is quoted if it contains spaces.  The 
launcher does not remove the extra quotes and fails.

I 'solved' by editing the pip.exe to remove the quotes.

ps - Windows programs are normally installed under c:\Program Files or 
c:\Program Files (x86).  That should be the default in the installer if 
possible.

Steve Dower added the comment:

I've previously reported this issue against setuptools (which generates the 
executable) and apparently they consider it a feature. I don't have the link 
handy from my phone, but if you find the issue on bitbucket you can help 
attract some more attention to this.

[issue23121] pip.exe breaks if python 2.7.9 is installed under c:\Program Files\Python

eryksun added the comment:

See issue 21699. This is fixed in distlib 0.1.9. The latest pip uses distlib 
0.2.0, so just update from pip 1.5.6 to 6.0.3.

C:\C:\Program Files\Python27\Scripts\pip.exe --version   

pip 6.0.3 from C:\Program Files\Python27\lib\site-packages (python 2.7)

Instructions for upgrading:

[Joshua Ellinger]

Joshua Ellinger added the comment:

Having pip not work after a straight install to the normal place you'd install 
it on windows can't be a feature.

Even after I changed the .exe, pip itself breaks on the same problem.  
Basically, you can't install python to
the normal place on windows until this is fixed.

[Joshua Ellinger]

Joshua Ellinger added the comment:

The safest fix would be to make subprocess strip double-quotes from the 
executable path.

Double quote () is not an allowed character in Windows file systems.  There is 
no case under 
which it can be correct to spawn a process in Windows where the path is quoted.

[issue23121] pip.exe breaks if python 2.7.9 is installed under c:\Program Files\Python

[Donald Stufft]

Donald Stufft added the comment:

If distlib 0.2.0 fixes this, then it should be fixed in pip 6+ when installing 
from Wheels. If the same problem exists in setuptools then it'll need to get 
fixed in setuptools (or pip will need to start writing it's own console scripts 
when installing from sdist too).

Will setuptools eventually switch to using distlib also? Currently setuptools 
has a different problem. Instead of errnously double quoting the EXE path, it 
doesn't quote it at all. As you can see in the cdb debugger output below, 
CreateProcessA is called without properly quoting the path to python.exe 
(register rdx is the 2nd parameter, lpCommandLine). 

C:\cdb C:\Program Files\Python27\Scripts\test.exe

So test.exe will actually run C:\program.exe, if it exists. For example:

C:\type program.c
#include stdio.h
int main(int argc, char *argv[])
{
int i;
for (i=0; i  argc; i++)
printf(%s\n, argv[i]);
return 0;
}

C:\dir /b C:\program.exe
program.exe

C:\C:\Program Files\Python27\Scripts\test.exe
C:\Program
Files\Python27\python.exe
C:\Program Files\Python27\Scripts\test-script.py
