Configure a Poetry environment
Poetry is a tool that facilitates creating a Python virtual environment based on the project dependencies. You can declare the libraries your project depends on, and Poetry will install and update them for you.
Project dependencies are recorded in the pyproject.toml file that specifies required packages, scripts, plugins, and URLs. See the pyproject reference for more information about its structure and format.
To use Poetry in PyCharm, you need to install it on your machine and create a specific Python environment.
Open Terminal (on macOS and Linux) or PowerShell (on Windows) and execute the following command:curl -sSL https://install.python-poetry.org | python3 -(Invoke-WebRequest -Uri https://install.python-poetry.org -UseBasicParsing).Content | py -curl -sSL https://install.python-poetry.org | python3 -
On macOS and Windows, the installation script will suggest adding the folder with the poetry executable to the PATH variable. Do that by running the following command:export PATH="/Users/jetbrains/.local/bin:$PATH"$Env:Path += ";C:\Users\jetbrains\AppData\Roaming\Python\Scripts"; setx PATH "$Env:Path"
Don't forget to replace
jetbrainswith your username!
To verify the installation, run the following command:poetry --version
You should see something like
Poetry (version 1.2.0).
Refer to the Poetry Installation Instructions for more details.
Create a Poetry environment
Do one of the following:
Click the Python Interpreter selector and choose Add New Interpreter.
Press Ctrl+Alt+S to open Settings/Preferences and go to . Click the Add Interpreter link next to the list of the available interpreters.
Click the Python Interpreter selector and choose Interpreter Settings. Click the Add Interpreter link next to the list of the available interpreters.
Select Add Local Interpreter.
In the left-hand pane of the Add Python Interpreter dialog, select Poetry Environment. The following actions depend on whether the virtual environment existed before.
To create a new environment, select Poetry Environment, and then do the following:
Select the base Python interpreter from the list, or click to browse for a Python executable.
If PyCharm doesn't detect the poetry executable, specify the following path in the Poetry executable field, replacing
jetbrainswith your username:/Users/jetbrains/Library/Application Support/pypoetry/venv/bin/poetryC:\Users\jetbrains\AppData\Roaming\pypoetry\venv\Scripts\poetry.exe/home/jetbrains/.local/bin/poetry
To use an existing environment:
Make sure that the project directory contains a pyproject.toml file.
Select Existing environment. Then expand the Interpreter list, and choose an interpreter or click to browse for a Python executable.
Click OK to complete the task.
If you select a poetry environment when creating a new Python project, PyCharm adds two files to your project:
pyproject.toml: specifies the project requirements
poetry.lock: records changes in the projects requirements
Each time you modify the pyproject.toml file, PyCharm notifies you and offers two actions: to record the changes in the poetry.lock file or to record the changes and install the unsatisfied requirements.
