creating a virtualenv using python (not jython) like this: pyenv virtualenv 2.7.12 test is OK and gives me no error

When running directly virtualenv ...

[x@Mac /Users/x]$ virtualenv -p ~/.pyenv/versions/jython-2.7.0/bin/jython yoshi

I am having an issue with this too.

I managed to get a little further by upgrading pip. But creation of the virtualenv was still not successful.

pyenv local jython-2.7.1
jython -m pip install --upgrade pip
pyenv virtualenv jython-2.7.1 multibeam-ingest-jython-2.7.1
