Install package with easy_install doesn't work due to long paths?


If I create a project in the default location (documents/visual studio...) then easy_install in my virtual env fails. This is true from PTVS or command line. If I create my project in a shorter path, I'm not seeing the issue.

However, from command line, if I use python -m easy_install mypackagename then it works even with long path.

Is the PTVS Install Package feature using easy_install.exe or python.exe -m easy_install ?

Example error (shows trying to install an .exe, but same error for regular package name such as azure):
C:\Users\huvalo\Documents\Visual Studio 2013\Projects\PyvotProgram1\PyvotProgram1\env\Scripts>easy_i
nstall.exe pywin32-219.win32-py2.7.exe
Fatal error in launcher: Unable to create process using '""c:\users\huvalo\documents\visual studio 2

Studio 2013\Projects\PyvotProgram1\PyvotProgram1\env\Scripts\easy_install.exe" pywin32-219.win32-py2

You may be looking at a setuptools bug. Unless there's a file alongside easy_install.exe named easy_install-script.py then we're just launching the launcher directly.

I suspect the problem is the double quoting around the path to python.exe, but I'm not sure where it came from.

If you open easy_install.exe in Notepad, you should see a shebang line near the end of the file. I suspect it will be quoted, but it shouldn't be. If it is, I'll file something for setuptools. (See if pip has the same problem.)

Pip may not have the same problem from PTVS because we go straight to "-m pip" (or '-c "import pip; pip.main()"' for older Pythons). But the pip.exe launcher may have the same issue.

I've repro'd this with the latest setuptools, so I'm reporting it to them.

virtual env in a path with spaces:
pip.exe and easy_install.exe both have the path to python.exe in double-quotes
pip works, easy_install doesn't

virtual env in a path without spaces:
pip.exe and easy_install.exe both have the path to python.exe NOT in double-quotes

This is tested with virtual env 1.11.6 for Python 2.7
