Poetry fails to find Git on Windows 10

[mrlegohead0x45]

• Poetry version: 1.31
• Python version: 3.10.4
• OS version and name: Windows 10
• pyproject.toml: n/a

• I am on the latest stable Poetry version, installed using a recommended method.
• I have searched the issues of this repo and believe that this is not a duplicate.
• I have consulted the FAQ and blog for any relevant entries or release notes.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option) and have included the output below.

powershell> poetry new pygame-test -vvv

Issue

Trying to create a new poetry project on windows 10 fails saying it hasn't found git.
I recently updated poetry from 1.1.13 to 1.3.1 by running poetry self update and copying ~\AppData\Roaming\pypoetry\venv\Scripts\poetry.exe to ~\AppData\Roaming\Python\Scripts\poetry.exe as suggested in #5377. That worked.
Then trying to create a new project via poetry new, poetry complains that it hasn't found a valid git executable, when git is in PATH, looking at the source code it trys to run %WINDIR%\\System32\\where.exe git, running this command in cmd finds git successfully.
Maybe poetry requires a newer version of git than 2.34 which I have, seeing that the latest is 2.39?

[neersighted]

Poetry shouldn't require a Git executable on Windows since we use Dulwich now. Can you please post the output of poetry config?

I would suggest you uninstall Poetry all together and reinstall it. My guess would be that something went wrong with 1.1.13 -> 1.3.1 migration and files got mixed up or something

[tonybarbieri]

@neersighted @Secrus I am hitting the same issue using a fresh install of poetry 1.4.0. I am on Windows using Powershell. I installed git and python using scoop. Running 'poetry new' I get the same stack trace as above.

check #5420

It seems that if the git.exe is in the sub-directory of the current folder will have this issue.
A temporary workaround is create a new folder and run poetry new in it.
