Hello,

I am tryint to install the python bindings to use pybel but I keep
gettin error messages.

I reinstalled openbabel in the 2.3.1 version and I am using python 3.7
version. I tried installing in these both ways:
https://openbabel.org/docs/current/UseTheLibrary/PythonInstall.html and
https://open-babel.readthedocs.io/en/latest/UseTheLibrary/PythonInstall.html
But I keep having problems.

This is the message it shows when I try to install it following the steps
in https://openbabel.org/docs/current/UseTheLibrary/PythonInstall.html

C:\Users\Rita>python -V
Python 3.7.3

C:\Users\Rita>obabel -V
Open Babel 2.3.1 -- Oct  9 2011 -- 17:57:01

C:\Users\Rita>obabel -Hsdf
sdf  MDL MOL format
Reads and writes V2000 and V3000 versions

Read Options, e.g. -as
 s  determine chirality from atom parity flags
       The default setting is to ignore atom parity and
       work out the chirality based on the bond
       stereochemistry.
 T  read title only
 P  read title and properties only
       When filtering an sdf file on title or properties
       only, avoid lengthy chemical interpretation by
       using the ``T`` or ``P`` option together with the
       :ref:`copy format <Copy_raw_text>`.

Write Options, e.g. -x3
 3  output V3000 not V2000 (used for >999 atoms/bonds)
 m  write no properties
 w  use wedge and hash bonds from input (2D structures only)
 A  output in Alias form, e.g. Ph, if present
