Pip trying to remove setuptools while installing something else

Question

I'm installing from a Pip requirements file that looks like this:

Mezzanine==1.2.4
# psycopg2==2.4.5
South==0.7.6
django-compressor==1.2

mezzanine-mdown==0.1a3
Pygments==1.5

which results in this error (django-appconf is a dependency of django-compressor):

[...]
  Running setup.py install for django-appconf

  Found existing installation: setuptools 0.6c11
    Uninstalling setuptools:
Exception:
Traceback (most recent call last):
  File "/home/adambrenecki/lib/python2.7/pip/basecommand.py", line 107, in main
    status = self.run(options, args)

    os.unlink(src)
OSError: [Errno 13] Permission denied: '/usr/local/bin/easy_install'

The weird thing is, whenever I install django-compressor (or any of the others) individually, it doesn't do this. It's only when I use the requirements file.

The full command I'm using to install is pip-2.7 install --install-option="--install-scripts=/home/[username]/webapps/[appname]/bin" --install-option="--install-lib=/home/[username]/webapps/[appname]/lib/python2.7" -r requirements.txt. I'm on one of WebFaction's servers, if that helps.

Does any of your packages has setuptools newer than 0.6c11 as dependency? Because if any of they have, they are going to uninstall and then install the newer version. — Hugo Lopes Tavares, Feb 18 '13 at 01:03
It ended up being something of the sort; in the end I just set up a virtualenv. I still don't get why each of the packages in my requirements.txt work individually but not when installed with `pip install -r`. — Daisy Leigh Brenecki, Feb 19 '13 at 01:45

Looks like a permission issue as described by :

OSError: [Errno 13] Permission denied: '/usr/local/bin/easy_install'

Try to "sudo" your command.

EDIT : There is a note in WebFaction's documentation about "Permission Denied" error available at the following adress http://docs.webfaction.com/software/python.html (scroll to the bottom of the page).

I can't, I don't have superuser privileges - as noted in the question, this is on the server of a shared hosting provider. I can install each package individually without it even attempting to touch `easy_install`, just not when I use a requirements file. – Daisy Leigh Brenecki Feb 07 '13 at 09:18
Also, per your edit: As the path `pip` is trying to write to doesn't begin with `/tmp` (and `easy_install` isn't a temporary file), the note you reference doesn't apply either. – Daisy Leigh Brenecki Feb 19 '13 at 01:48
