geojson to json --missing multiple row output

[yoshi]

thank you again.

i tried this
pip install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org pip setuptools
saying :requirement already satisfied .

then tried pip install pandas again. No luck.

also geopandas i tried but it doesnot recognize this module as well. I am sorry.
