Installing Python module from within code inside ArcGIS Pro script tool

I am trying to install a third-party Python package from within a Python script so that other users can run the script and the package can be installed and loaded without having to manually download and install. This is the code I'm using:

 

    import subprocess
   
def install(package):
       
subprocess.call([sys.executable, "-m", 'pip', 'install', package])
   
   
install('pyodbc')
   
import pyodbc

This seems to work fine from within my stand-alone Python script. However, when I try to run it as a script tool set up in ArcGIS Pro, it is not finding the installed package and is failing with this error message:

 

    ModuleNotFoundError: No module named 'pyodbc'

Does anyone know what the issue is? Do I need to change a path or environment setting?
