如何用不同的 python 版本配置 python 虚拟环境?
原标题:How to configure python virtual environment with different python version?
I am trying to set virtual environment with a different python version. The default global version is Python 3.11.0 I have installed virtualenv using pip install virtualenv Command to create virtualenv with different python version is virtualenv -p "C:/Python310/python.exe" .venv Error when I run the above command is RuntimeError: failed to query C:Python310python.exe with code 1 err: Traceback (most recent call last): File "C:Python311Libsite-packagesvirtualenvdiscoverypy_info.py", line 8, in import json File "C:Python311libjson\__init__.py", line 106, in from .decoder import JSONDecoder, JSONDecodeError File "C:Python311libjsondecoder.py", line 3, in import re File "C:Python311lib e\__init__.py", line 125, in from . import _compiler, _parser File "C:Python311lib e\_compiler.py", line 18, in assert _sre.MAGIC == MAGIC, "SRE module mismatch" AssertionError: SRE module mismatch Not sure what I am missing here. Any guidance is appreciated.

If possible in your environment, i like to use conda for venvs + multiple python versions like: # Download conda from https://www.anaconda.com/products/distribution # Create conda env - python 3.7 conda create -n python-3.7 python=3.7 # activate and initialize virtual env conda activate python-3.7 # make another! conda create -n python-3.8 python=3.8 # activate and initialize virtual env conda activate python-3.8 NOTE - I use a Mac, I think its just as smooth on Windows but im not 100% sure :D
