python 诗歌安装在 Windows 10 上失败 - 没有 pyvenv.cfg 文件

Question

I installed Python 3.9 using winget.

PS C:\Users\andre> winget list PythonSoftware
Name       ID                                                Version
-----------------------------------------------------------------------
Python 3.9 PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0 3.9.2544.0

I am trying to install poetry. Therefore, I downloaded the new installation script from https://install.python-poetry.org/ and run it within a Windows terminal. Here's the output:

PS C:\Users\andre\Downloads> python .\install-poetry.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\andre\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\LocalCache\local-packages\Scripts

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

See C:\Users\andre\Downloads\poetry-installer-error-bzs5mfpr.log for error logs.

And finally the output of the respective log file:

No pyvenv.cfg file

Apparently, there's some issue with the place where Python has been installed, isn't it? How can I solve that issue?

Answer 1

This indeed is path issue with multiple versions of Python Installation, especially the version from Microsoft is not setting the path properly us the installer from https://www.python.org/downloads/ it fixes the error
