Virtualenv - text file busy

Administrators
1

I have indico 2.0 running on a development VM. If I log in as indico and try to invoke the virtualenv I get the error below. If I stop indico-celery.service, the virtualenv starts normally.

Should I be using virtualenv once indico is up and running? If so, how do I fix this?

Regards,

Chris

virtualenv ~/.venv creates a new virtualenv, so it’s not what you want here. To activate the virtualenv, use source ~/.venv/bin/activate
