Error during installing Indico version 3

I tried to install the Indico version 3 using the steps available on the following link (Apache — Indico 3.0-dev documentation) and I received the following error.

pip install indico

Any idea?

Indico 3 is not released yet so installing it from PyPI is not yet possible.

I’m not sure why you get this VERY ancient 1.2 though; I’d expect pip to give you 2.3.5 (which would also fail to install on Python 3 as 2.x requires Python 2.7).

If you want to test 3.0, here’s an up to date wheel: indico-3.0.dev0+202106101552.b012c92b2b-py3-none-any.whl (41.5 MB)

  • no guarantees that it’s stable
  • there are no plugins for 3.0 released to pypi yet either (so don’t try to install any indico plugins via pip)
