Fatal error in launcher: Unable to create process

Question

Searching the net this seems to be a problem caused by spaces in the Python installation path.

How do I get pip to work without having to reinstall everything in a path without spaces ?

Answer 1

it seems that

python -m pip install XXX 

will work anyway (worked for me) (see link by user474491)

Answer 2

I had this issue and the other fixes on this page didn't fully solve the problem.

What did solve the problem was going in to my system environment variables and looking at the PATH - I had uninstalled Python 3 but the old path to the Python 3 folder was still there. I'm running only Python 2 on my PC and used Python 2 to install pip.

Deleting the references to the nonexistent Python 3 folders from PATH in addition to upgrading to the latest version of pip fixed the issue.

Answer 3

This is a known Bug when there is a space in the virtualenv path. Correction has been made, and will be available in the next version.

Answer 4

u need enter someone \Scripts change all file.exe to file27.exe,then it solve

my D:\Python27\Scripts edit django-admin.exe to django-admin27.exe so it done

Answer 5

Here's how I solved it:

1. open pip.exe in 7zip and extract __main__.py to Python\Scripts folder.

   In my case it was C:\Program Files (x86)\Python27\Scripts

2. Rename __main__.py to pip.py

3. Run it! python pip.py install something

EDIT:

If you want to be able to do pip install something from anywhere, do this too:

1. rename pip.py to pip2.py (to avoid import pip errors)

2. make C:\Program Files (x86)\Python27\pip.bat with the following contents:

python "C:\Program Files (x86)\Python27\Scripts\pip2.py" %1 %2 %3 %4 %5 %6 %7 %8 %9

1. add C:\Program Files (x86)\Python27 to your PATH (if is not already)

2. Run it! pip install something
