Communal Causes of the Mistake
Respective components tin lend to the “Nary module named pkg_resources” mistake. A communal script is an incomplete oregon corrupted setuptools set up. This tin happen throughout a defective Python set up oregon once dependencies struggle. Digital environments, designed to isolate task dependencies, tin besides brush this content if setuptools isn’t decently put in inside the situation itself.
Different offender may beryllium outdated variations of setuptools. Utilizing an older interpretation mightiness deficiency compatibility with newer packages oregon Python variations, triggering the mistake. Successful any instances, the mistake mightiness originate from conflicts betwixt antithetic Python installations connected your scheme. If your task is referencing the incorrect Python set up, it whitethorn not discovery the required pkg_resources module.
Troubleshooting and Options
Resolving the “Nary module named pkg_resources” mistake frequently entails guaranteeing setuptools is appropriately put in and configured. Statesman by checking if setuptools is immediate successful your actual situation utilizing pip entertainment setuptools. If not, instal it by way of pip instal setuptools.

pkg_resources seems to beryllium distributed with setuptools. Initially I idea this mightiness not beryllium put in to the Python successful the virtualenv, truthful I put in setuptools 2.6 (aforesaid interpretation arsenic Python) to the Python tract-packages successful the virtualenv with the pursuing bid:
sh setuptools-zero.6c11-py2.6.ovum --instal-dir /var/www/mydir/virtualenvs/dev/lib/python2.6/tract-packages
EDIT: This lone occurs wrong the virtualenv. If I unfastened a console extracurricular the virtualenv past pkg_resources is immediate, however I americium inactive getting the aforesaid mistake.
