|

This script will install Poetry and its dependencies.
|
||||
|
||||
It does, in order:
|
||||
|
||||
- Downloads the virtualenv package to a temporary directory and add it to sys.path.
|
||||
- Creates a virtual environment in the correct OS data dir which will be
|
||||
- `%APPDATA%\\pypoetry` on Windows
|
||||
- ~/Library/Application Support/pypoetry on MacOS
|
||||
- `${XDG_DATA_HOME}/pypoetry` (or `~/.local/share/pypoetry` if it's not set) on UNIX systems
|
||||
- In `${POETRY_HOME}` if it's set.
|
||||
- Installs the latest or given version of Poetry inside this virtual environment.
|
||||
- Installs a `poetry` script in the Python user directory (or `${POETRY_HOME/bin}` if `POETRY_HOME` is set).
