Commands You’ve already learned how to use the command-line interface to do some things. This chapter documents all the available commands. To get help from the command-line, simply call poetry to see the complete list of commands, then --help combined with any of those can give you more information. Global options --verbose (-v|vv|vvv): Increase the verbosity of messages: “-v” for normal output, “-vv” for more verbose output and “-vvv” for debug. --help (-h) : Display help information. --quiet (-q) : Do not output any message. --ansi: Force ANSI output. --no-ansi: Disable ANSI output. --version (-V): Display this application version. --no-interaction (-n): Do not ask any interactive question. --no-plugins: Disables plugins. --no-cache: Disables Poetry source caches. --directory=DIRECTORY (-C): The working directory for the Poetry command (defaults to the current working directory). new This command will help you kickstart your new Python project by creating a directory structure suitable for most projects.

All command-line arguments will be resolved relative to the current working directory or directory specified using --directory option if used. new This command will help you kickstart your new Python project by creating a directory structure suitable for most projects.

Building Extension Modules Warning While this feature has been around since almost the beginning of the Poetry project and has needed minimal changes, it is still considered unstable. You can participate in the discussions about stabilizing this feature here. And as always, your contributions towards the goal of improving this feature are also welcome. Poetry allows a project developer to introduce support for, build and distribute native extensions within their project. In order to achieve this, at the highest level, the following steps are required.

Dependency specification Dependencies for a project can be specified in various forms, which depend on the type of the dependency and on the optional constraints that might be needed for it to be installed. project.dependencies and tool.poetry.dependencies Prior Poetry 2.0, dependencies had to be declared in the tool.poetry.dependencies section of the pyproject.toml file. [tool.poetry.dependencies] requests = "^2.13.0" With Poetry 2.0, you should consider using the project.dependencies section instead. [project] # ... dependencies = [ "requests (>=2.23.0,<3.0.0)" ] While dependencies in tool.poetry.dependencies are specified using toml tables, dependencies in project.dependencies are specified as strings according to PEP 508.
