--exists-action option does not work

[pawroman]

While running command:
pip-accel install --exists-action=s -r requirements.txt

I get:
Executing command: pip install --download-cache=/home/.../.pip_download_cache --find-links=file:///... --build-directory=/tmp/... --exists-action=s -r requirements.txt --no-install An error occurred during configuration: option --exists-action: invalid choice: ['s'] (choose from 's', 'i', 'w', 'b')

Using pip 1.4.1, pip-accel 0.10.2, Python 2.7.3

So far I can't reproduce this, which is strange because my environment seems exactly the same:

What operating system are you using? Also, I can't imagine this error being dependent on the contents of requirements.txt file, but just to be sure then: Can you reproduce this with the requirements.txt bundled with pip-accel?

FWIW I have run into this also. Looks like it's a bug that was in pip 1.4.1 but has since been fixed.

@xolox - Not sure why you couldn't repro? Oh, or maybe you were on the develop branch? Anyhow, more reasons for upgrading to pip1.5x?! :)
