pip not working on hombrew python 2.7 install

I've installed python using homebrew and I can't invoke pip from the bash. I've tried amending my .bash_profile to include /usr/local/bin/python and /usr local/share/python to no avail.

When I use the bash command:

find / -name 'pip'

The only results I get are:

/Library/Python/2.7/site-packages/pip-1.5.6-py2.7.egg/pip
/Users/Ivan/Library/Caches/pip
/Users/Ivan/Library/Logs/pip
/usr/local/Cellar/python/2.7.9/libexec/pip
/usr/local/Cellar/python/2.7.9/libexec/pip/pip
/usr/local/lib/python2.7/site-packages/pip

None of which are an executable.

I don't really know where to point my $PATH as I can't find the pip executable. When I open

/usr/local/lib/python2.7/site-packages/pip

or

/usr/local/Cellar/python/2.7.9/libexec/pip/pip

I find the following files:

__init__.py         commands            operations
__init__.pyc        compat              pep425tags.py
__main__.py         download.py         pep425tags.pyc
__main__.pyc        download.pyc        req
_vendor             exceptions.py       status_codes.py
basecommand.py      exceptions.pyc      status_codes.pyc
basecommand.pyc     index.py            utils
baseparser.py       index.pyc           vcs
baseparser.pyc      locations.py        wheel.py
cmdoptions.py       locations.pyc       wheel.pyc
cmdoptions.pyc      models

None of which are an executable.

I would appreciate the help of anyone with more experience than me.

Edit: I tried the steps suggested by Marco:

Here are the results to the steps:

  1. echo $PATH shows a few directories: /usr/local/bin:/usr/local/mysql/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/texbin:/opt/X11/bin:/usr/local/mysql/bin

  2. which -a python returns: /usr/local/bin/python /usr/local/bin/python

nothing is returned for which -a pip

  1. which python returns: /usr/local/bin/python

nothing is returned for which pip

  1. ls -l $(which python) returns a single directory: lrwxr-xr-x 1 Ivan admin 33 17 May 08:59 /usr/local/bin/python -> ../Cellar/python/2.7.9/bin/python

ls -l $(which pip) returns several, including the python files that I showed in my original post


Generally, homebrew will install a formula into /usr/local/Cellar/formula and then place a link at /usr/local/bin/formula.

To make use of your installed formulae, make sure /usr/local/bin is in your $PATH. Show your $PATH by typing

echo $PATH

If /usr/local/bin is not in your $PATH, put this line at the end of your ~/.profile file.

export PATH="/usr/local/bin:$PATH"

Now, check what pythons are found on your OSX by typing:

which -a python

There should be one python found at /usr/bin/ (the Apple python) and one at /usr/local/bin/ which is the Homebrew python.

which python

will show you, which python is found first in your $PATH and will be executed when you invoke python.

If you want to know, where the executable is, show it by typing

ls -l $(which python)

This could look like this: lrwxr-xr-x 1 root wheel 68 7 Mai 13:22 python -> /usr/local/bin/python

This will work for pip as well.

If you show the results of this steps, we can probably help you much easier.

-- UPDATE --

You have /usr/local/bin/python linked to /usr/local/Cellar/python/2.7.9/bin/python. -> brew install python worked.

show, if pip is installed by typing

brew list python | grep pip

You should see

/usr/local/Cellar/python/2.7.9/bin/pip

If not, check, if there are links, which are not done with brew install. Told you something like this:

"Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local"

To force the link and overwrite all conflicting files:

brew link --overwrite python

To list all files that would be deleted:

brew link --overwrite --dry-run python

** NO standard Apple /usr/bin/python **

link from /usr/local/Cellar/python/2.7.9/bin/python to /usr/bin/python

ln -s /usr/local/Cellar/python/2.7.9/bin/python /usr/bin/python

This is necessary for all python scripts beginning with #!/usr/bin/python. Especialy easy_install will fail, if link is not there.

Now, you are able to run

easy_install pip

Hope, you're making progress


If brew is managing your python install and pip is no longer symlinked (i.e. you type "which pip" and get no results) try this from your home directory:

brew unlink python && brew link python

Not sure if the old method works any more (it didn't on my machine).

Now confirm it does indeed point to your 2.7 installation with pip --version (it will list the python major version in the directory output).
