install-poetry.py - Poetry was not installed with the recommended installer.

[posidron]

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Windows 10
• Poetry version: 1.1.6

Issue

I used to install poetry via pip which worked fine for build and publish, however installing from a private registry failed with whatever I tried with "package with version is not available" error and hence tried the official installer to be able to use the preview version in hopes it's a bug and it might have been fixed.

I downloaded the install-poetry.py and installed it again via this script.

> python .\install-poetry.py
[ Added AppData to Path ]
> poetry self update --preview

It should not tell me that I did not install it with the recommended installer I believe.

i got the same problem on linux. poetry self update will fail with the same warning even though it was installed that way.

did a fresh install followed by self update to reproduce the issue

# 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:

/home/USER/.local/bin

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

Installing Poetry (1.1.6): Done

Poetry (1.1.6) is installed now. Great!

You can test that everything is set up by executing:

`poetry --version`

➜  ~ poetry self update

Please see #4012 (comment) for details on why this happens.

[tfranzel]

@abn i see. depending on how far away 1.2 is, i would consider doing a 1.1.7 that accounts for that issue. not the best UX that a fresh install is broken by design.

[abn]

The amount of work required for that is not trivial. For a 1.1.z install we never recommended the install-poetry.py script. And that fix won't work for versions older than 1.1.7 either because users do specify versions on installs as well.

All that said, I suspect the issue here is folks using the github readme to get started as opposed to the official published documentation. As an interim measure I will update the README to expand on the existing warning and add "migration" steps so it can be used later on anyway. Further, I wil also add a warning during the script installation noting that the self upgrade comand will not work when poetry < 1.2.0.a0 is used.
