[question] How to use poetry on Ubuntu?

I made a poetry-based project on Manjaro, where python3 is the default.

On another machine, which has Ubuntu 18.04, I wanted to re-create the virt. env. but I got the following error:

$ poetry install                              
/home/jabba/.poetry/lib/poetry/_vendor/py2.7/subprocess32.py:149: RuntimeWarning: The _posixsubprocess module is not being used. Child process reliability may suffer if your program uses threads.
  "program uses threads.", RuntimeWarning)
                                                                              
[RuntimeError]                                                 
The current Python version (2.7.15) is not supported by the project (^3.6)  
Please activate a compatible Python version.

Under my Ubuntu python points to Python 2.7, it’s true, but Ubuntu has a python3 symlink that points to Python 3.6.

I think poetry should pick Python 3 automatically. But anyway, how can I create a Python 3 virt. env. in this case? Thanks.

OK, I found a way (using https://github.com/sdispater/poetry/issues/721):

Install with Python 3:

curl -sSL https://raw.githubusercontent.com/sdispater/poetry/master/get-poetry.py | python3

Then edit the file ~/.poetry/bin/poetry and change the first line to:

#!/usr/bin/env python3

That is, python is changed to python3.

The bad news is that if you update poetry to a new version, this change will be overwritten very likely.

this workaround is not working for me on ubuntu 18.04
