Import yaml error on pum

[ponceta]

I can't launch pum commands

pum -v

tells me he can't find yaml Module

ModuleNotFoundError: No module named 'yaml'

Pum version 0.7.1 Pyyaml version 3.13

Python version 3.6.7 on Ubuntu 18.04.1 LTS

Virtual env is used for python 3

pum and pyyaml have been updated using

sudo pip3 install pum --upgrade sudo pip3 install pyyaml --upgrade

There's a strange message about rights below, this is maybe the main reason why all of this is broken:

The directory '/home/pulmexa/.cache/pip' or its parent directory is not owned by the current user and caching wheels has been disabled. check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

???

you should not pip install with raw sudo. Use -H as said in message.

I cleaned pum and pyyaml using pip3 uninstall and reinstalled

sudo -H pip3 uninstall pum

sudo -H pip3 install pum

(tutorial-env) pulmexa@ubuntu:~/qgep_sigip$ sudo -H pip3 install pum

launching a python3 console still result in :

>>> import yaml

Solved... Ubuntu 18.04.1 LTS has python3 by default, no more need for venv!
