Question: I'm playing with poetry because I'm thinking about switching from pip. Following the basic usage examples, I'm doing the following: $ poetry new poetry-demo $ cd poetry-demo $ poetry add django $ django-admin #can't find it $ poetry shell #or poetry $(poetry env info --path)/bin/activate $ django-admin Traceback (most recent call last): File "/Users/cjones/Library/Caches/pypoetry/virtualenvs/poetry-demo-Jq168aNm-py3.8/bin/django-admin", line 5, in <module> from django.core.management import execute_from_command_line ModuleNotFoundError: No module named 'django'  Also tried in this order: $ poetry new poetry-demo $ cd poetry-demo $ poetry shell #or poetry $(poetry env info --path)/bin/activate $ poetry add django $ django-admin Traceback (most recent call last): File "/Users/cjones/Library/Caches/pypoetry/virtualenvs/poetry-demo-Jq168aNm-py3.8/bin/django-admin", line 5, in <module> from django.core.management import execute_from_command_line ModuleNotFoundError: No module named 'django'  Check the pyproject.toml: [tool.poetry] name = "poetry-demo" version = "0.1.0" description = "" authors = ["Your Name <you@example.com>"] [tool.poetry.dependencies] python = "^3.8" Django = "^3.2.6" [tool.poetry.dev-dependencies] pytest = "^5.2" [build-system] requires = ["poetry-core>=1.0.0"] build-backend = "poetry.core.masonry.api"  Check poetry show: asgiref 3.4.1 ASGI specs, helper code, and adapters attrs 21.2.0 Classes Without Boilerplate django 3.2.6 A high-level Python Web framework that encourages rapid development and clean, pragmatic design. more-itertools 8.8.0 More routines for operating on iterables, beyond itertools packaging 21.0 Core utilities for Python packages pluggy 0.13.1 plugin and hook calling mechanisms for python py 1.10.0 library with cross-python path, ini-parsing, io, code, log facilities pyparsing 2.4.7 Python parsing module pytest 5.4.3 pytest: simple powerful testing with Python pytz 2021.1 World timezone definitions, modern and historical sqlparse 0.4.1 A non-validating SQL parser. wcwidth 0.2.5 Measures the displayed width of unicode strings in a terminal  Check the path where it says it is not and there it is: $ ls -l $(poetry env info --path)/bin total 144 -rw-r--r-- 1 cjones staff 2197 Aug 27 09:39 activate -rw-r--r-- 1 cjones staff 1489 Aug 27 09:39 activate.csh -rw-r--r-- 1 cjones staff 3120 Aug 27 09:39 activate.fish -rw-r--r-- 1 cjones staff 1751 Aug 27 09:39 activate.ps1 -rw-r--r-- 1 cjones staff 1199 Aug 27 09:39 activate_this.py -rwxr-xr-x 1 cjones staff 339 Aug 27 09:39 django-admin -rwxr-xr-x 1 cjones staff 729 Aug 27 09:39 django-admin.py -rwxr-xr-x 1 cjones staff 297 Aug 27 09:39 pip -rwxr-xr-x 1 cjones staff 297 Aug 27 09:39 pip-3.8 -rwxr-xr-x 1 cjones staff 297 Aug 27 09:39 pip3 -rwxr-xr-x 1 cjones staff 297 Aug 27 09:39 pip3.8 -rwxr-xr-x 1 cjones staff 281 Aug 27 09:39 py.test -rwxr-xr-x 1 cjones staff 281 Aug 27 09:39 pytest lrwxr-xr-x 1 cjones staff 128 Aug 27 09:39 python -> /Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/Resources/Python.app/Contents/MacOS/Python lrwxr-xr-x 1 cjones staff 6 Aug 27 09:39 python3 -> python lrwxr-xr-x 1 cjones staff 6 Aug 27 09:39 python3.8 -> python -rwxr-xr-x 1 cjones staff 292 Aug 27 09:39 sqlformat -rwxr-xr-x 1 cjones staff 284 Aug 27 09:39 wheel -rwxr-xr-x 1 cjones staff 284 Aug 27 09:39 wheel-3.8 -rwxr-xr-x 1 cjones staff 284 Aug 27 09:39 wheel3 -rwxr-xr-x 1 cjones staff 284 Aug 27 09:39 wheel3  Deactivate and reactive the venv. I've restarted the shell. Still just get: Traceback (most recent call last): File "/Users/cjones/Library/Caches/pypoetry/virtualenvs/poetry-demo-Jq168aNm-py3.8/bin/django-admin", line 5, in <module> from django.core.management import execute_from_command_line ModuleNotFoundError: No module named 'django'  Suggestions for what is up here and how to resolve it?

Answer: Should have read this more closely: https://python-poetry.org/docs/basic-usage/#using-poetry-run poetry run django-admin
