-------------------------------+-------------------------
Reporter: veroandreo | Owner: grass-dev@…
Type: defect | Status: new
Priority: critical | Milestone: 7.8.0
Component: Temporal | Version: svn-trunk
Keywords: temporal, python3 | CPU: x86-64
Platform: Linux |
-------------------------------+-------------------------
Temporal modules do not work with python3 in virtualenv. In a mapset where
I have strds, I run `t.list` and I get:
{{{

Same if I try to create a stds with `t.create`, ask info with `t.info` and
so on...
All temporal functionality is up and running in 76 release branch though.
