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:
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
which -a python returns: /usr/local/bin/python /usr/local/bin/python
nothing is returned for which -a pip
- which python returns: /usr/local/bin/python
nothing is returned for which pip
- 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).
