ImportError: No module named pip

问题:

OS: Mac OS X 10.7.5 Python Ver: 2.7.5

I have installed setuptools 1.0 with ez_setup.py from https://pypi.python.org/pypi/setuptools Then I download pip.1.4.1 pkg from https://pypi.python.org/pypi/pip/1.4.1.

Run "[sudo]python setup.py install" in iTerm shows that

Then I inputed "pip install", the error message showed like that

Traceback (most recent call last): File "/Library/Frameworks/Python.framework/Versions/2.7/bin/pip", line 9, in load_entry_point('pip==1.4.1', 'console_scripts', 'pip')() File "build/bdist.macosx-10.6-intel/egg/pkg_resources.py", line 357, in load_entry_point File "build/bdist.macosx-10.6-intel/egg/pkg_resources.py", line 2394, in load_entry_point File "build/bdist.macosx-10.6-intel/egg/pkg_resources.py", line 2108, in load ImportError: No module named pip

Anyone who met the same problem before and can give me some tips to solve it?

回答1:

I had the same problem. My solution:

For Python 3

sudo apt-get install python3-pip

For Python 2

sudo apt-get install python-pip

回答2:

On Mac using brew is a better option as apt-get is not available. Command:

In case you have both python2 & python3 installed on machine

python2.7 -m ensurepip --default-pip

simply should solve the issue.

If instead you are missing pip from python 3 then simply change python2.7 to python3 in the command above.

回答3:

After installing ez_setup, you should have easy_install available. To install pip just do:

easy_install pip

回答4:

I ran into this same issue when I attempted to install the nova client.

spencers-macbook-pro:python-novaclient root# python  setup.py install    
running install
/usr/bin/python: No module named pip
error: /usr/bin/python -m pip.__init__ install   'pbr>=0.5.21,<1.0' 'iso8601>=0.1.4' 'PrettyTable>=0.6,<0.8' 'requests>=1.1' 'simplejson>=2.0.9' 'six' 'Babel>=0.9.6' returned 1

I use homebrew so I worked around the issue with sudo easy_install pip

spencers-macbook-pro:python-novaclient root# brew search pip
aespipe     brew-pip    lesspipe    pipebench   pipemeter   spiped  pipeviewer

If you meant "pip" precisely:

Homebrew provides pip via: `brew install python`. However you will then
have two Pythons installed on your Mac, so alternatively you can:
    sudo easy_install pip
spencers-macbook-pro:python-novaclient root# sudo easy_install pip

The commands should be similar if you use macports.

回答5:

I think none of these answers above can fix your problem.

I was also confused by this problem once. You should manually install pip following the official guide pip installation (which currently involves running a single get-pip.py Python script)

after that, just sudo pip install Django. The error will be gone.

回答6:

I know this thread is old, but I just solved the problem for myself on OS X differently than described here.

Basically I reinstalled Python 2.7 through brew, and it comes with pip.

Install Xcode if not already:

xcode-select –install

Install Brew as described here:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Then install Python through Brew:

brew install python

And you're done. In my case I just needed to install pyserial.

pip install pyserial

回答7:

I downloaded pip binaries from here and it resolved the issue.

回答8:

In terminal try this:

ls -lA /usr/local/bin | grep pip

in my case i get:

-rwxr-xr-x 1 root  root      284 Сен 13 16:20 pip
-rwxr-xr-x 1 root  root      204 Окт 27 16:37 pip2
-rwxr-xr-x 1 root  root      204 Окт 27 16:37 pip2.7
-rwxr-xr-x 1 root  root      292 Сен 13 16:20 pip-3.4

So pip2 || pip2.7 in my case works, and pip

回答9:

I solved a similar error on Linux by setting PYTHONPATH to the site-packages location. This was after running python get-pip.py --prefix /home/chet/pip.

[chet@rhel1 ~]$ ~/pip/bin/pip -V
Traceback (most recent call last):
  File "/home/chet/pip/bin/pip", line 7, in <module>
    from pip import main
ImportError: No module named pip

[chet@rhel1 ~]$ export PYTHONPATH=/home/chet/pip/lib/python2.6/site-packages

[chet@rhel1 ~]$ ~/pip/bin/pip -V
pip 9.0.1 from /home/chet/pip/lib/python2.6/site-packages (python 2.6)

回答10:

try to install pip through python:

please go to https://pip.pypa.io/en/stable/installing/

and download get-pip.py, and then run:

(sudo) python get-pip.py
