Problems with Installing exoplanet in Window System

I followed the instruction in _Notes about running on Windows_ at _https://docs.exoplanet.codes/en/stable/user/install/_.
The first three lines run well, but the last one: **python -m pip install -e .[test]** produces this on my computer:
**ERROR: File "setup.py" not found. Directory cannot be installed in editable mode: D:\Python\Jupyter Notebook**,
and I can't find out what's wrong.
