invalid command 'egg_info'

[emirotin]

Getting this error when trying to install any package, like:

sudo pip install pyserial
sudo pip install --upgrade pip

or even

sudo ./get-pip.py

at the same moment easy_install works fine

Mac OSX, python 2.7, pip 0.8.2, distribute 0.6.16 from macports

Attempting to replicate

mkvirtualenv -p python2.7
pip uninstall pip
easy_install -f http://d.pypi.python.org/packages/source/p/pip/pip-0.8.2.tar.gz#md5=df1eca0abe7643d92b5222240bed15f6 pip==0.8.2
pip 0.8.2 from /Users/pnasrat/Development/.virtualenvs/pip-upgrade/lib/python2.7/site-packages/pip-0.8.2-py2.7.egg (python 2.7)

I then did

pip install distribute==0.6.16
pip install pyserial

That worked for me.

Can you paste the full output of what occurs when you try these commands. You can use three backticks to mark the start and end of a block - see the GitHub Flavored Markdown link above the comment box in the issue.

I, in reverse, have installed distribute and pip with macports, and am not using virtualenv (I need the majority of packages to be available system-wide)

Full output of
sudo pip install --upgrade pip:

I've just installed macports from the dmg and done

sudo port install python27
sudo port install py27-distribute
sudo port install py27-pip

Giving

sudo pip-2.7 --version
pip 1.0.1 from /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages (python 2.7)

Then I can do

sudo pip-2.7 install -U pip

Can you paste in

sudo port list installed

[emirotin]

Yes, please find here: http://pastebin.com/TndgVa3c
Strange enough, my ports installation doesn't suggest pip-1.0.1

[hltbra]

egg_info is a setuptool's feature, maybe your distribute package has problems...

Is there any good reason to use macports to install pip and distribute? I strongly recommend you to not use macports (or any other OS system package) to install python packages, because OS package maintainers use to customize things and I remember Debian and Ubuntu breaking setuptools's package.

[emirotin]

well, yes, I know it might be because of distribute, but distribute itself is working fine
regarding mac ports: no, no special need for that, just because at the moment I was installing pip easy_install was the recommended way, as far as I remember, and I didn't want installing something from sources (not because of laziness, but because I want as much as possible to be behind some package manager)

passing macports in this cases means installing distribute from sources - correct? I mean, is it still needed for pip install?

[hltbra]

Pip still needs distribute/setuptools...

You can install them easily with:

$ curl -O http://python-distribute.org/distribute_setup.py
$ python distribute_setup.py

$ curl -O https://github.com/pypa/pip/raw/master/contrib/get-pip.py
$ python get-pip.py

[emirotin]

well, regarding distribute - I discovered that some (macports) packages depend on it, and these packages, I suppose, are in turn requirements for other packages.
but I re-installed fresh distribute and pip (btw, curl for github requires -k to ignore certificate warning) - now pip is 1.0.1 and is working fin, thanks!

re #286 (comment)

sudo port install py27-pip
sudo pip-2.7 --version
pip 1.0.1 from /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages (python 2.7)

That's really strange as pip 1.0.1 is not in ports yet: http://www.macports.org/ports.php?by=name&substr=py27-pip

Anyway, thanks in advance!
