ERROR: The executable argonaut/bin/python is not functioning

ERROR: It thinks sys.prefix is '/home/jaywink' (should be '/home/jaywink/argonaut')

ERROR: virtualenv is not compatible with this system or executable

 

The issue is an old virtualenv version the go-pylons.py script uses, which doesn't import the necessary modules. Not to fear, installing is still easy, just grab the newest virtualenv source or on Ubuntu do:

 

sudo apt-get install python-virtualenv

 

Then just run the following as per Pylons installation instructions:

 

virtualenv mydevenv

mydevenv/bin/easy_install Pylons==1.0
