[FIX] odoo-shippable: Solve issues after dropped support of Python3.3
requested to merge github/fork/vauxoo-dev/master-python3.3_freeze_virtualenv_version-luisg into master
This applies the following fixes, mostly related to issues due to dropped support for Python3.3:
- Freeze virtualenv version: Starting from version 16.0, virtualenv is not compatible with Python 3.3 anymore. Therefore, the virtualenv version needs to be freezed for that Python version.
- Don't install virtualenv twice: virtualenv was being installed again when creating environments for all Python versions
- Print messages when installing pip for all versions
- Fix small typos in messages printed when creating virtualenvironments
- Add a missing
$
character in the library (my bad) - Remove redundant parameter
-p
when creating virtualenvs - Install all Odoo versions from Vauxoo and Odoo; V11 was not being installed
Closes #309 (closed)
