Issue

Decided to install poetry. No idea if I already had an installation or not (recovered machine from old backup) but poetry was not working so I assumed not. Followed instructions on python-poetry.org. During the installation, found that the installation script was out of date. Cancel installation with SIGTERM via Ctrl-C (if this doesn't rollback installation, it should, or at least not leave the system in a broken state).

Decided to install via the new install-poetry.py script. Everything seemed dandy. Added poetry to my path as instructed.

Immediately, just in case, I tested poetry self update. I got two different results depending on if I was using git-bash or windows powershell.

In Powershell, I got this error (shown with -vvv)

On git bash, I received an entirely different error (I'm assuming it was actually the same error, however on top of this some character that you're using to generate the output is causing encoding issues).

So clearly, there's some kind of conflict somewhere, given the mention of a ~/.poetry directory which doesn't exist. Which means either

• update.py doesn't know where it's supposed to be (thinks it is in the wrong place) and is causing this issue
  • but I can't find anything here...
• I have borked my install beyond compare and don't know what to do in order to fix it

Here's the big problem... I know Python, and this current = Path(__file__) implies that current should be the path to the update script in the correct location...but isn't. Which means either

• there's some super weird caching going on
• something in poetry is mucking with __file__

To test this, I manually edited that code to print out __file__ on error, and, well,

__file__='c:\\users\\[redacted]\\appdata\\roaming\\pypoetry\\venv\\lib\\site-packages\\poetry\\console\\commands\\self\\update.py'
self.home=WindowsPath('C:/Users/[redacted]/.poetry')

Digging around the code, self.home is based on POETRY_PATH. Which means either

• things are installing to the wrong location for some reason
• my POETRY_PATH should be set during the installation process, but it wasn't.

Note: I manually redacted my username and replaced it with [redacted] for personal reasons. In retrospect I should have just replaced it with "steinj13" since that's roughly equivalent to my github username, but I'm tired and didn't sync it in my head.

@13steinj I suspect you would have seen this during your installation

poetry/install-poetry.py

Lines 428 to 433 in 925429f

	colorize(
	"warning",
	f"You are installing {version}. When using the current installer, this version does not support "
	f"updating using the 'self update' command. Please use 1.2.0a1 or later.",
	)
	)

Python versions prior to 1.2.x installed via the (in-preview) install-poetry.py script will not be able to perform self-update as the install mechanisms are quite different. You can use the --preview flag to get the latest preview release.

@abn Perhaps I got that message and didn't notice, odd.

Though I fail to understand something here-- the official documentation on the website says the installer you should use is get-poetry.py

Running this installer, however, tells you you aren't using the recommended installer and to use install-poetry.py.

If I don't want to use the preview version, because I'm not a fan of alpha relesses, which script do I use? Will I then when 1.2.0 releases be able to use self update? Or at minimum, be able to somehow migrate from 1.1.x to 1.2.0 and then from that point on be able to use self update?

Poetry is great software, but upgrading and installing shouldn't be so convoluted. It turns people away from using it in the first place. I don't know the details behind the change in installation script, directory, etc, but currently installing poetry from scratch is a bit of a mess in what one has to do and where one has to go in order to do it.
