I'm installing poetry
using the get-poetry.py
script, and I want to specify the version to install. To install the latest version I do
GET_POETRY_URL=https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py
curl -sSL $GET_POETRY_URL | python
The get-poetry.py
script takes an argument --version
, but how do I pass that through?
curl -sSL $GET_POETRY_URL | python --version 1.1.4
prints the installed python version, rather than passing the argument through to the get-poetry.py
script. I could save the script to a file and call it that way, but I'm doing this in a docker image and I don't want to deal with cleaning it up afterwards.
curl -sSL $GET_POETRY_URL | python - --version 1.1.4
Using -
as the script location when you call python
will cause it to read from stdin. As usual, any arguments after the script location are passed to the script:
$ echo "import sys; print(sys.argv)" | python - --version 1.1.4
['-', '--version', '1.1.4']
Using -
to mean stdin also works for many other unix tools:
$ echo hello | cat -
hello
