# Python Poetry Installer
|
|
This repository contains Poetry's official installation script, installer source and
|
|
related hosting configuration.
|
|
|
|
The script is hosted on [Vercel](https://vercel.com/) and made available at
|
|
https://install.python-poetry.org/.
|
|
|
|
## Usage
|
|
|
|
Poetry provides a custom installer that will install `poetry` isolated
|
|
from the rest of your system.
|
|
|
|
### osx / linux / bashonwindows / Windows+MinGW install instructions
|
|
```bash
|
|
curl -sSL https://install.python-poetry.org | python -
|
|
```
|
|
### windows powershell install instructions
|
|
```powershell
|
|
(Invoke-WebRequest -Uri https://install.python-poetry.org -UseBasicParsing).Content | python -
|
|
```
|
|
|
|
**Warning**: The previous `get-poetry.py` installer is now deprecated, if you are currently using it
|
|
you should migrate to the new, supported, `install-poetry.py` installer.
|
|
|
|
The installer installs the `poetry` tool to Poetry's `bin` directory. This location depends on your system:
|
|
|
|
- `$HOME/.local/bin` for Unix
|
|
- `%APPDATA%\Python\Scripts` on Windows
|
|
|
|
If this directory is not on your `PATH`, you will need to add it manually
|
|
if you want to invoke Poetry with simply `poetry`.
|
|
|
|
Alternatively, you can use the full path to `poetry` to use it.
|
|
|
|
Once Poetry is installed you can execute the following:
|
|
|
|
```bash
|
|
poetry --version
|
|
```
|
|
|
|
If you see something like `Poetry (version 1.2.0)` then you are ready to use Poetry.
|
|
If you decide Poetry isn't your thing, you can completely remove it from your system
|
|
by running the installer again with the `--uninstall` option or by setting
|
|
the `POETRY_UNINSTALL` environment variable before executing the installer.
|
|
|
|
```bash
|
|
python install-poetry.py --uninstall
|
|
POETRY_UNINSTALL=1 python install-poetry.py
|
|
```
|
|
|
|
By default, Poetry is installed into the user's platform-specific home directory.
|
|
If you wish to change this, you may define the `POETRY_HOME` environment variable:
|
|
|
|
```bash
|
|
POETRY_HOME=/etc/poetry python install-poetry.py
|
|
```
|
|
|
|
If you want to install prerelease versions, you can do so by passing `--preview` option to `install-poetry.py`
|
|
or by using the `POETRY_PREVIEW` environment variable:
|
|
|
|
```bash
|
|
python install-poetry.py --preview
|
|
POETRY_PREVIEW=1 python install-poetry.py
|
|
```
|
|
|
|
Similarly, if you want to install a specific version, you can use `--version` option or the `POETRY_VERSION`
|
|
environment variable:
|
|
|
|
```bash
|
|
python install-poetry.py --version 1.2.0
|
|
POETRY_VERSION=1.2.0 python install-poetry.py
|
|
```
|
|
|
|
You can also install Poetry for a `git` repository by using the `--git` option:
|
|
|
|
```bash
|
|
python install-poetry.py --git https://github.com/python-poetry/poetry.git@master
|
|
````
|
|
|
|
**Note**: Note that the installer does not support Python < 3.6.
|
|
|
|
|
|
## Known Issues
|
|
|
|
### Debian/Ubuntu
|
|
|
|
On Debian and Ubuntu systems, there are various issues that maybe caused due to how
|
|
various Python standard library components are packaged and configured. The following
|
|
details issues we are presently aware of, and potential workarounds.
|
|
|
|
> **Note:** This can also affect WSL users on Windows.
|
|
|
|
#### Installation Layout
|
|
If you encounter an error similar to the following, this might be due to
|
|
[pypa/virtualenv#2350](https://github.com/pypa/virtualenv/issues/2350).
|
|
|
|
```console
|
|
FileNotFoundError: [Errno 2] No such file or directory: '/root/.local/share/pypoetry/venv/bin/python'
|
|
```
|
|
|
|
You can work around this issue by setting the `DEB_PYTHON_INSTALL_LAYOUT` environment
|
|
variable to `deb` in order to emulate previously working behaviour.
|
|
|
|
```sh
|
|
export DEB_PYTHON_INSTALL_LAYOUT=deb
|
|
```
|
|
|
|
#### Missing `distutils` Module
|
|
|
|
In certain Debian/Ubuntu environments, you might encounter the following error message
|
|
in error logs (`poetry-installer-error-*.log`) provided when the installer fails.
|
|
|
|
```console
|
|
ModuleNotFoundError: No module named 'distutils.cmd'
|
|
```
|
|
|
|
This is probably due to [this bug](https://bugs.launchpad.net/ubuntu/+source/python3.10/+bug/1940705).
|
|
See also [pypa/get-pip#124](https://github.com/pypa/get-pip/issues/124).
|
|
|
|
The known workaround for this issue is to reinstall the `distutils` package provided by
|
|
the distribution.
|
|
|
|
```sh
|
|
apt-get install --reinstall python3-distutils
|
|
```
|
|
|
|
If you have installed a specific python version, eg: `3.10`, you might have to use the
|
|
package name `python3.10-distutils`.
