I had a very similar issue, since I am using a portable python app which comes via an installer. As the other answers indicate, there is a hard coded path within the .exe which points to python in the original installer configuration.
The issue is that it's not just pip.exe, ipython.exe, or jupyter.exe that use this hard-coded path, but at least 20+ compiled exe scripts in the .\python\Scripts folder. The solution, in my case, is not to re-install each module since that breaks the idea of the portable package. Plus, this will require additional internet resources which might not be available for the user.
The solution is to replace the path to the python.exe in the compiled scripts themselves. Here is the solution which worked for me, from a previous example:
This is the code incase the link breaks:
"""
Patch the distribution to make it portable
"""
import os
import sys
def win_patch_paths(folder, python_path, path_to_python="", fLOG=print):
"""
path are absolute when they are installed,
see `Create a portable Python with Pip on Windows <http://www.clemens-
sielaff.com/create-a-portable-python-with-pip-on-windows/>`_
:param folder: folder when to find the executable
:param python_path: python path (string to replace)
:param path_to_python: new python path (replace by)
:param fLOG: logging function
:return: list of tuple ('exe or py', 'modified file')
The first three parameter can be environment variables.
They will be replaced by their values.
"""
