[w-Bro]

i want to switch to a higher python version for my project, after i type pdm use 3.8 i got an error like this

pdm use 3.8 -v
Traceback (most recent call last):

    raise NoPythonVersion("Python interpreter is not found on the system.")
pdm.exceptions.NoPythonVersion: Python interpreter is not found on the system.

pyproject.toml
requires-python = ">=3.7"

pdm info
PDM version:        1.13.6
Python Interpreter: D:\Miniconda3\python.EXE (3.7)
Project Root:       D:/xxx/xxx
Project Packages:   D:\xxx\xxx\__pypackages__\3.7

Is it necessary that i must have a higher version on my computer if i want to switch to it? And i did not get a answer from the document, https://pdm.fming.dev/usage/project/#choose-a-python-interpreter.

Yes, you must install Python 3.8 (and others) yourself before being able to use it with PDM.
To install a particular Python version, you can use pyenv, conda, your system's package manager, MSI installers if you are on Windows, compile and install from sources, etc.

emm, it's different with what i imagine about pdm, i thought it will auto-download one.
