Hello,
yesterday I succeeded to upgrade an old indico 1.2 version (which was on an old OpenSuSE machine) to 2.0 on a new machine (with CentOS Linux 7)
Next step was to upgrade from 2.0 to newer version.
I used the command on this page: https://docs.getindico.io/en/latest/installation/upgrade/
But the command pip install -U indico stops with the message in red:
pyrsistent requires Python ‘>=3.5’ but the running Python is 2.7.5
Any solution??
Cheers, Henk
Output I get:
source ~/.venv/bin/activate
(.venv) [indico@rock35 ~]$ export PATH="$PATH:/usr/pgsql-9.6/bin"
(.venv) [indico@rock35 ~]$ pip install -U indico
