Eclipse/PyDev无法找到已安装的distro模块，如何配置PYTHONPATH？

现象说明 #

终端执行pip list显示distro模块已安装（版本1.9.0），但在Eclipse/PyDev中运行Salt Minion启动脚本时，抛出ModuleNotFoundError: No module named 'distro'错误。

终端pip list输出 #

已完成的环境准备步骤 #

• 克隆Salt源码到~/SaltSource/3006.9：

  git clone https://github.com/dnessett/salt
  

• 切换到3006.x分支并检出v3006.9标签：

  git switch -t origin/3006.x
  git checkout tags/v3006.9
  

• 以可编辑模式安装源码：

  python -m pip install -e .
  

• 使用pyenv指定Python 3.10.15解释器：

  sudo pyenv local 3.10.15
  

当前pip版本信息 #

dnessett@homelserv:~/SaltSource/3006.9$ which pip
/home/dnessett/.pyenv/shims/pip

dnessett@homelserv:~/SaltSource/3006.9$ pip --version
pip 22.0.2 from /usr/lib/python3/dist-packages/pip (python 3.10)

提问 #

是否需要修改PYTHONPATH以包含已安装模块？若需要，该如何配置？
