Poetry install

[aspergil1us]

Hello! I'm having a big problem with installing poetry. When I try to install it command,
(Invoke-WebRequest -Uri https://install.python-poetry.org -UseBasicParsing).Content | py -
I get a message saying that it's already installed.

However, when I request the version, it tells me that it's not available.

Can you help me understand the reason for this? I'm using the Windows operating system.

Poetry is already installed. The installer found a matching version in %APPDATA%\pypoetry, but the poetry wrapper is not on your PATH, so PowerShell reports the command as unavailable.

The official installer puts the executable in %APPDATA%\Python\Scripts. Confirm the binary, then add that folder to your user PATH:

& "$env:APPDATA\pypoetry\venv\Scripts\poetry.exe" --version
[Environment]::SetEnvironmentVariable("Path", [Environment]::GetEnvironmentVariable("Path", "User") + ";$env:APPDATA\Python\Scripts", "User")

Close that terminal and open a new one before running poetry --version. PATH updates do not apply to windows that were already open.

If Python came from the Microsoft Store, the wrapper can land under %LOCALAPPDATA%\Packages\PythonSoftwareFoundation.Python.*\LocalCache\Roaming\Python\Scripts instead. Put that folder on PATH, or keep calling the full poetry.exe path above.

Poetry is already installed on your system in %APPDATA%\pypoetry, but its binary wrapper was not added to your Windows PATH environment variable.

Step 1: Verify the executable

Run this command in PowerShell to confirm Poetry runs directly:

& "$env:APPDATA\pypoetry\venv\Scripts\poetry.exe" --version

Step 2: Add Poetry to your User PATH

Add the default scripts directory to your User PATH variable:

[Environment]::SetEnvironmentVariable("Path", [Environment]::GetEnvironmentVariable("Path", "User") + ";$env:APPDATA\Python\Scripts", "User")

Step 3: Restart Terminal

Close your current PowerShell window and open a new one (environment updates do not affect active sessions). Then test:

poetry --version

Hope this helps fix your path issue!
