I have just update my Mac from Snow Leopard to Lion. I then needed to install virtualenv and virtualenvwrapper. I used for both easy_install.
I also added virtualenvwrapper settings to my .bash_profile file as following:
# virtualenvwrapper settings
export WORKON_HOME="~/virtualenvs"
source "/usr/local/bin/virtualenvwrapper.sh"
But when sourcing it I get the following error:
ERROR: Could not create temporary file name. Make sure TMPDIR is set.
virtualenvwrapper.sh: There was a problem running the initialization hooks.
If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenv has been installed for VIRTUALENVWRAPPER_PYTHON=/Library/Frameworks/Python.framework/Versions/2.7/bin/python and that PATH is set properly.
Thank you all for your help.
