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).
For more information, refer to the Poetry Installation Instructions.
Create a Poetry environment
Do one of the following:
Click the Python Interpreter selector and choose Add New Interpreter.
Press Control+Alt+S to open Settings 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 you want to create a new Poetry environment or to use an existing one.
- New Poetry environment
Select Poetry Environment.
Choose the base interpreter from the list, or click and find the desired Python executable in your file system.
If your project contains pyproject.toml, you can choose whether you want to install the packages listed in it by enabling or disabling the Install packages from pyproject.toml checkbox. By default, the checkbox is enabled.
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
- Existing Poetry environment
Make sure that the project directory contains a pyproject.toml file.
Select Existing environment. Then expand the Interpreter list and choose the desired interpreter.
If the desired interpreter is not on the list, click, and then browse for the Python executable within the previously configured Poetry environment.
The selected Poetry environment will be reused for the current project.
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 (poetry lock) or to record the changes and install the unsatisfied requirements (poetry update).
Create a Poetry environment using pyproject.toml
When you open a project that contains pyproject.toml, but no project interpreter is configured, PyCharm suggests that you create a Poetry environment.
Click Set up a poetry environment using pyproject.toml if you want PyCharm to configure Poetry for you automatically. Alternatively, you can click Configure Python interpreter to follow the standard workflow.
If PyCharm cannot autodetect the Poetry executable, specify the path to it and click OK.
A new Poetry environment will be configured for your project and the packages listed in pyproject.toml will be installed.
