# ##### Setup Runtime Venv #####

# Create a virtual environment for poetry to use, upgrade pip in that venv to a pinned
|

|
# version, then install the current project to the venv.

|
#
|
||
|
|
# Note 1: Poetry, Tox, and this project plugin all use pip under the hood for package
|
||
|
|
# installation. This means that even though we are creating up to eight venvs
|
||
|
|
# during a given CI run they all share the same download cache.
|
||
|
|
# Note 2: The "VIRTUAL_ENV=$CI_VENV" prefix on the poetry commands below sets the venv
|
||
|
|
# that poetry will use for operations. There is no CLI flag for poetry that
|
||
|
|
# directs it to use a given environment, but if it finds itself in an existing
|
||
|
|
# environment it will use it and skip environment creation.
