Python hat ein wirklich sehr groß entwickeltes Ökosystem, mit ganz vielen Tools, die man erst mal finden muss und dann im zweiten Step auch nutzen können muss.
Hier geht es heute um pipenv
Installation
sudo apt install pipenv
Virtuelle Umgebung anlegen
Wir wechseln ins Projektverzeichnis
cd /home/$USER/projekt1
Die Entwicklungsumgebung anlegen
pipenv --python 3.8
Die Entwicklungsumgebung starten
frank@frank-MS-7C37:~/restic_ui$ pipenv shell
Spawning environment shell (/bin/bash). Use 'exit' to leave.
frank@frank-MS-7C37:~/restic_ui$ . /home/frank/.local/share/virtualenvs/restic_ui-RwXjz-0W/bin/activate
(restic_ui-RwXjz-0W) frank@frank-MS-7C37:~/restic_ui$ pipenv
Usage: pipenv [OPTIONS] COMMAND [ARGS]...
Options:
--where Output project home information.
--venv Output virtualenv information.
--py Output Python interpreter information.
--envs Output Environment Variable options.
--rm Remove the virtualenv.
--bare Minimal output.
--completion Output completion (to be eval'd).
--man Display manpage.
--three / --two Use Python 3/2 when creating virtualenv.

-h, --help Show this message and exit.
Usage Examples:
Create a new project using Python 3.6, specifically:
$ pipenv --python 3.6
Install all dependencies for a project (including dev):
$ pipenv install --dev
Create a lockfile containing pre-releases:
$ pipenv lock --pre
Show a graph of your installed dependencies:
$ pipenv graph
Check your installed dependencies for security vulnerabilities:
$ pipenv check
Install a local setup.py into your virtual environment/Pipfile:
$ pipenv install -e .
Use a lower-level pip command:
$ pipenv run pip freeze
Commands:
check Checks for security vulnerabilities and against PEP 508 markers
provided in Pipfile.
clean Uninstalls all packages not specified in Pipfile.lock.
graph Displays currently–installed dependency graph information.
install Installs provided packages and adds them to Pipfile, or (if none
is given), installs all packages.
lock Generates Pipfile.lock.
open View a given module in your editor.
run Spawns a command installed into the virtualenv.
shell Spawns a shell within the virtualenv.
sync Installs all packages specified in Pipfile.lock.
uninstall Un-installs a provided package and removes it from Pipfile.
update Runs lock, then sync.
