virtualenvwrapper.sh: fork: Resource temporarily unavailable - Python/Django

Question

What do I have to do to successfully launch virtualenvwrapper.sh? What do I need to put into my .bashrc?

The error message :

/Library/Frameworks/Python.framework/Versions/2.7/bin/virtualenvwrapper.sh: fork: Resource temporarily unavailable 
#When I launch the terminal I see it twice, when I launch it manually I see the error message only once.

I want to install Python/Django and followed this manual :

• download and install python,
• install setuptools-8.2.1,
• install pip,
• pip django, pip pillow,
• sudo install virtualenv, sudo install virtualenvwrapper

virtualenvwrapper.sh can be found in (not in /usr/local/bin):

/Library/Frameworks/Python.framework/Versions/2.7/bin/virtualenvwrapper.sh

The virtualenvwrapper folder can be found in:

/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/virtualenvwrapper

My .bashrc I edited as followed:

export PYTHONPATH=$PYTHONPATH/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages

export VIRTUALENVWRAPPER_PYTHON=/Library/Frameworks/Python.framework/Versions/2.7/bin/virtualenvwrapper.sh

export WORKON_HOME=$HOME/.virtualenvs
source /Library/Frameworks/Python.framework/Versions/2.7/bin/virtualenvwrapper.sh

After studying related posts I tried:

• reinstall all packages via pip
• reinstall pip
• kill -9 to make sure all there are not too many open processes

Thank you for your help in advance!

I think this:

export VIRTUALENVWRAPPER_PYTHON=/Library/Frameworks/Python.framework/Versions/2.7/bin/virtualenvwrapper.sh

Should be something like (for me it is python3, but I see you are using python2):

export VIRTUALENVWRAPPER_PYTHON=/Library/Frameworks/Python.framework/Versions/2.7/bin/python
