Install and use pandas on Plone

I want to parse an excel file with pandas.
I have installed pandas with:

$ pip install pandas

file.py:

import pandas
...

But when i start the Plone client on fg:

$ ./client-debug fg

This line get me the error:

ModuleNotFoundError: No module named 'pandas'

Anybody know how to use pandas on Plone and help me?
Thank in advance.

Normally Plone installs are managed with buildout, not pip.
https://docs.plone.org/manage/installing/installing_addons.html#installing-add-ons-using-buildout should help you with installing pandas.

I have a 5.2 install where pgeocode depends on pandas. This was done by simply adding it to my eggs section.

    Plone
    mr.developer
    Pillow
    pdf2image
    pgeocode

and in a viewlet:

    def get_location_info(self, postal_code):
        """ returns a pandas.DataFrame object
            see: https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.html
        """
        nomi = pgeocode.Nominatim('de')
        results = nomi.query_postal_code(postal_code).to_dict()

        return results

I think I got it working (locally) with ( I used plotly and numpy too, but they might require / depend on some of the same stuff):

install_requires=[
      'plotly',
      'pandas',
      'numpy',
  ],
