No module named pkg_resources

I'm deploying a Django app to a dev server and am hitting this error when I run pip install -r requirements.txt:

Traceback (most recent call last):
  File "/var/www/mydir/virtualenvs/dev/bin/pip", line 5, in <module>
    from pkg_resources import load_entry_point
ImportError: No module named pkg_resources

pkg_resources appears to be distributed with setuptools. Initially I thought this might not be installed to the Python in the virtualenv, so I installed setuptools 2.6 (same version as Python) to the Python site-packages in the virtualenv with the following command:

sh setuptools-0.6c11-py2.6.egg --install-dir /var/www/mydir/virtualenvs/dev/lib/python2.6/site-packages

EDIT: This only happens inside the virtualenv. If I open a console outside the virtualenv then pkg_resources is present, but I am still getting the same error.

Any ideas as to why pkg_resources is not on the path?

For people finding this question in 2025 or after:

Installing setuptools as proposed by most answers does work, but you should really replace pkg_resources with importlib.

For example, use

from importlib.metadata import version
version("pyjwt")

instead of

import pkg_resources
pkg_resources.get_distribution("pyjwt").version

I use conda virtual environment as well. And I use ROS to run the code. I've tried different versions setuptools (reinstall and install many times), but it did not work for me.

ImportError: cannot import name 'packaging' from 'pkg_resources' (/opt/ros/noetic/lib/python3/dist-packages/pkg_resources/init.py)

If I run which python, it shows the python in conda virtual environment.

/home/<use_name>/miniconda3/envs/ros_env/bin/python

So the problem is probably the python from the virtual environment try to find the package from the ros environment, which causes the problem. This can happen due to the way Python paths are set up.

Make sure that your Conda environment's Python paths are prioritized. You can modify the PYTHONPATH environment variable to prioritize your Conda environment's paths.

export PYTHONPATH="/home/<user_name>/miniconda3/envs/ros_env/lib/python3.8/site-packages:$PYTHONPATH"

Problem solved for me.

I caused this error (or very similar) by removing the "/Library/Python/2.7/site-packages/" directory from my machine thinking it was a local cache. Only easy_install stopped working (pip was fine).

None of the items listed here helped me but I was able to recover by downloading the latest from https://www.python.org/downloads/ and installing it. Luckily I was not on latest, as I believe otherwise I would have had to reinstall.

I suspect (but not 100% sure) I also needed to open a new terminal (or new tab in terminal) to have it work.

I encountered this error in a poetry environment.

Steps I took to resolve it:

Add setuptools as a dev dependency with

poetry add --dev setuptools

Install setuptools in the poetry env using

poetry run pip install setuptools

I ran into this problem after installing the latest Python version 3.10.4. Somehow, the setuptools package and pip were deleted.

I used the following command to resolve the issue : in [Windows]

py -m ensurepip --default-pip

You can use the command sudo apt-get install --reinstall python3-pkg-resources if you are using python3 , this was the case with me.

A lot of answers are recommending the following but if you read through the source of that script, you'll realise it's deprecated.

wget https://bootstrap.pypa.io/ez_setup.py -O - | python

If your pip is also broken, this won't work either.

pip install setuptools

I found I had to run the command from Ensure pip, setuptools, and wheel are up to date, to get pip working again.

python -m pip install --upgrade pip setuptools wheel

the simple resoluition is that you can use conda to upgrade setuptools or entire enviroment. (Specially for windows user.)

conda upgrade -c anaconda setuptools

if the setuptools is removed, you need to install setuptools again.

conda install -c anaconda setuptools

if these all methodes doesn't work, you can upgrade conda environement. But I do not recommend that you need to reinstall and uninstall some packages because after that it will exacerbate the situation.

On Windows, with python 3.7, this worked for me:

pip install --upgrade setuptools --user

--user installs packages in your home directory, which doesn't require admin privileges.

In my case, I had 2 python versions installed initially and later I had deleted the older one. So while creating the virtual environment

virtualenv venv

was referring to the uninstalled python

What worked for me

python3 -m virtualenv venv

Same is true when you are trying to use pip.

July 2018 Update

Most people should now use pip install setuptools (possibly with sudo).

Some may need to (re)install the python-setuptools package via their package manager (apt-get install, yum install, etc.).

This issue can be highly dependent on your OS and dev environment. See the legacy/other answers below if the above isn't working for you.

Explanation

This error message is caused by a missing/broken Python setuptools package. Per Matt M.'s comment and setuptools issue #581, the bootstrap script referred to below is no longer the recommended installation method.

The bootstrap script instructions will remain below, in case it's still helpful to anyone.

Legacy Answer

I encountered the same ImportError today while trying to use pip. Somehow the setuptools package had been deleted in my Python environment.

To fix the issue, run the setup script for setuptools:

wget https://bootstrap.pypa.io/ez_setup.py -O - | python

(or if you don't have wget installed (e.g. OS X), try

curl https://bootstrap.pypa.io/ez_setup.py | python

possibly with sudo prepended.)

If you have any version of distribute, or any setuptools below 0.6, you will have to uninstall it first.*

See Installation Instructions for further details.

* If you already have a working distribute, upgrading it to the "compatibility wrapper" that switches you over to setuptools is easier. But if things are already broken, don't try that.

If you are encountering this issue with an application installed via conda, the solution (as stated in this bug report) is simply to install setup-tools with:

conda install setuptools

I have had the same problem when I used easy-install to install pip for python 2.7.14. For me the solution was (might not be the best, but worked for me, and this is probably the simplest) that the folder that contained the easy-install.py also contained a folder pkg_resources, and i have copy-pasted this folder into the same folder where my pip-script.py script was (python27\Scripts). Since then, I found it in the python27\Lib\site-packages\pip-9.0.1-py2.7.egg\pip\_vendor folder as well, it might be a better solution to modify the pip-script.py file to import this.

If you are using Python 3, you should use pip3 instead of pip. The command looks like $ pip3 install requirements.txt

After trying several of these answers, then reaching out to a colleague, what worked for me on Ubuntu 16.04 was:

pip install --force-reinstall -U setuptools
pip install --force-reinstall -U pip

In my case, it was only an old version of pillow 3.1.1 that was having trouble (pillow 4.x worked fine), and that's now resolved!

I had this error earlier and the highest rated answer gave me an error trying to download the ez_setup.py file. I found another source so you can run the command:

curl http://peak.telecommunity.com/dist/ez_setup.py | python

I found that I also had to use sudo to get it working, so you may need to run:

sudo curl http://peak.telecommunity.com/dist/ez_setup.py | sudo python

I've also created another location that the script can be downloaded from:

I ran into this problem after updating my Ubuntu build. It seems to have gone through and removed set up tools in all of my virtual environments.

To remedy this I reinstalled the virtual environment back into the target directory. This cleaned up missing setup tools and got things running again.

e.g.:

~/RepoDir/TestProject$ virtualenv TestEnvironmentDir

For me, it turned out to be a permissions problem on site-packages. Since it's only my dev environment, I raised the permissions and everything is working again:

sudo chmod -R a+rwx /path/to/my/venv/lib/python2.7/site-packages/

Looks like they have moved away from bitbucket and are now on github (https://github.com/pypa/setuptools)

Command to run is:

wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python

just reinstall your setuptools by :

$ sudo wget https://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz#md5=7df2a529a074f613b509fb44feefefe74e
$ tar -zxvf setuptools-0.6c11.tar.gz
$ cd setuptools-0.6c11/
$ sudo python setup.py build
$ sudo python setup.py install
$ sudo pip install --upgrade setuptools

then everything will be fine.
