No module named pkg_resources
Solution 1
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.

sudo apt-get install --reinstall python-pkg-resources
fixed it for me in Debian. Seems like uninstalling some .deb packages (twisted set in my case) has broken the path python uses to find packages
Solution 3
I have seen this error while trying to install rhodecode to a virtualenv on ubuntu 13.10. For me the solution was to run
pip install --upgrade setuptools
pip install --upgrade distribute
before I run easy_install rhodecode.
Solution 4
It also happened to me. I think the problem will happen if the requirements.txt contains a "distribute" entry while the virtualenv uses setuptools. Pip will try to patch setuptools to make room for distribute, but unfortunately it will fail half way.
The easy solution is delete your current virtualenv then make a new virtualenv with --distribute argument.
An example if using virtualenvwrapper:
$ deactivate
$ rmvirtualenv yourenv
$ mkvirtualenv yourenv --distribute
$ workon yourenv
$ pip install -r requirements.txt

In CentOS 6 installing the package python-setuptools fixed it.
yum install python-setuptools

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 withsetuptools
. Initially I thought this might not be installed to the Python in the virtualenv, so I installedsetuptools 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?
