pdm init raises FileNotFoundError if a clean pyenv installation is present

[ferminho]

• I have searched the issue tracker and believe that this is not a duplicate.

Steps to reproduce

• Install latest pyenv (v2.3.5)
• Install pdm 2.1.5
• Do pdm init in any folder

Can be reproduced building the following Docker image:

FROM python:3.9.7-slim AS base

RUN apt-get update && apt-get install -y git curl
ENV PYENV_GIT_TAG v2.3.5
RUN curl https://pyenv.run | bash
RUN pip install pdm==2.1.5
RUN pdm init -v -n

Actual behavior

An exception is raised

Expected behavior

pdm init executes normally, ignoring the clean pyenv installation

It seems it's caused by frostming/findpython#10

[frostming]

Fixed on the new release of findpython

Thank you! Verified, it works in 2.2.0
