This "Official Installer Script" fails on Windows#146

Installed on an up-to-date vanilla Windows 11 machine with Python 3.13 (symlinks enabled), via the official method recommended right here on the website:

PS C:\Users\me> (Invoke-WebRequest -Uri https://install.python-poetry.org -UseBasicParsing).Content | py -
Retrieving Poetry metadata

# Welcome to Poetry!

This will download and install the latest version of Poetry,
a dependency and package manager for Python.

It will add the `poetry` command to Poetry's bin directory, located at:

C:\Users\alexander.chandel\AppData\Roaming\Python\Scripts

You can uninstall at any time by executing this script with the --uninstall option,
and these changes will be reverted.

Installing Poetry (1.8.4)
Installing Poetry (1.8.4): Creating environment
Installing Poetry (1.8.4): Installing Poetry
Installing Poetry (1.8.4): Creating script
Installing Poetry (1.8.4): Done

Poetry (1.8.4) is installed now. Great!

To get started you need Poetry's bin directory (C:\Users\me\AppData\Roaming\Python\Scripts) in your `PATH`
environment variable.

Alternatively, you can call Poetry explicitly with `C:\Users\me\AppData\Roaming\Python\Scripts\poetry`.

You can test that everything is set up by executing:

`poetry --version`
PS C:\Users\me> C:\Users\me\AppData\Roaming\Python\Scripts\poetry --version
PS C:\Users\me>

Ok so the installation failed somehow. Calling it explicitly outputs nothing. And it did not bother to add that dir to my USER PATH for me, so it isn't really an "install". Let's add it to the PATH and try again:

PS C:\Users\me> poetry --version
PS C:\Users\me> poetry -h
PS C:\Users\me> poetry -foobar
PS C:\Users\me>

No output at all, literally nothing.

Let's try the absolute path, just in case:

PS C:\Users\me> C:\Users\me\AppData\Roaming\pypoetry\venv\Scripts\poetry.exe --version
PS C:\Users\me> C:\Users\me\AppData\Roaming\pypoetry\venv\Scripts\poetry.exe -h
PS C:\Users\me>

Still nothing. What's going on?

    I am quite sure that the installer works fine for lots of people: it is likely that whatever problem you are experiencing is something unusual in your local environment.

    Do leave an update if and when you figure it out, perhaps the next person will benefit.

    I am quite sure that the installer works fine for lots of people: it is likely that whatever problem you are experiencing is something unusual in your local environment.

    And? This is relevant in what way?

    Do leave an update if and when you figure it out,

    The person asked for help and you dismissed them

    ... perhaps the next person will benefit.

    Well, actually, "I am quite sure that the installer works fine for lots of people," so there will not be a "next person" who needs to benefit from the unusual something that the user will figure out for themselves.

    tldr

    Using Python v3.13 is the likely nexus of the problem. Modify the command to

    (Invoke-WebRequest -Uri https://install.python-poetry.org -UseBasicParsing).Content | py -3.12 -

    Chronological troubleshooting

    About a week ago, I ran (Invoke-WebRequest -Uri https://install.python-poetry.org -UseBasicParsing).Content | py - from an admin ps

    poetry --version produced nothing
    I tried using it a few times with things like poetry init but I never got a response or error or anything. for example:

    (hhSCNet) C:\apps\hhSCNet>poetry 
(hhSCNet) C:\apps\hhSCNet>poetry --help
(hhSCNet) C:\apps\hhSCNet>poetry help

    Today, I uninstalled with (Invoke-WebRequest -Uri https://install.python-poetry.org -UseBasicParsing).Content | py - --uninstall and the script said it was uninstalled.
    I reinstalled from admin PS. same problem.

    Switched to non-admin PS

    I haven't tried any other command, so maybe it is still broken, but getting a response was major improvement, so I decided to share with y'all.

    My point in noting that the installer works for lots of people is simply that: it generally isn't true that the installer "fails on windows".

    If the script did generally fail, then anyone could reproduce the problem and offer help: whereas if it fails only on the reporter's computer then only the reporter is positioned to do any debugging. (A second report now puts us somewhere in between.)

    In an earlier comment I linked to a pipeline succeeding with windows and python 3.13 so the issue is certainly not simply about using python 3.13. I would guess that it's not about that at all; but maybe.

    I still have little to offer on this one but encouragement: if you figure out what is going on please do leave an update. Perhaps the next person will benefit.

    it generally isn't true that the installer "fails on windows".

    • False: This fails on all Windows systems.
    • True: This fails on my Windows system.
    • True: This fails on a five-USB-port computer.
    • True: This fails on Windows.

    The original post can be criticized for many things, but this is not one of them.

    I can echo the issue, C:\Users\<username>\AppData\Roaming\Python\Scripts isn't even created
    3.6 fails with

    Installing Poetry (2.1.3): An error occurred. Removing partial environment.
Poetry installation failed.

    And then tries to write a log to C:\Users\<username>\AppData\Roaming\, but no such log is ever created
    3.13 and 3.12 instead report success, but as I said they don't even create C:\Users\<username>\AppData\Roaming\Python\Scripts

    I'm on windows 11
