Recently the company I work for (Giant Digital) made the decision to move away from Pipenv as the main Python packaging tool to Poetry, as a result I had to install Poetry to work on some of the newer projects.
I found that using the install instructions for Poetry persistently resulted in environments with a Python2.7 dependency.
[tool.poetry.dependencies] python = "^2.7"
After searching around on Google I came across a frequently recommended install script which was supposed to install Poetry with a Python3 depedency.
curl -SSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python3
This failed to change the Python dependency to Python3.
Next I stumbled across another popular recommendation to modify **~/.poetry/bin/poetry** to.
Notice the change to **python3**
This did not work either.
Finally, the solution I found which actual worked was to add the following alias entry to **.zshrc** and/or **.bashrc**
alias poetry="python3 $HOME/.poetry/bin/poetry"
This resulted in Python3.7 being set as the dependency.
[tool.poetry.dependencies] python = "^3.7"
At this moment I am unsure as to whether this is an Ubuntu only issue or is persistent across other Debian based distros. That being said I do hope that this article may be of some use to someone else who may be in a similar situation.
