Blog Post How To Install External Python Modules in Universal Agent

A technical how-to on installing external Python modules by Colin Cocksedge, Director of Product Management at Stonebranch

This is a technical how-to on installing external python modules on Stonebranch's UA (Universal Agent). Users utilizing the bundled UA python environment may require external modules not delivered with the UA python environment. In Windows, you may find that you see the following error when trying to use pip to install these modules:

“C:\Program Files\universal\python36\scripts\pip3 install requests”
pip fatal error in launcher: unable to create process using ‘”‘

This is because we install in the “C:\Program Files” location. In order to install the required python modules, you can run the following commands from a command prompt (replacing "requests" with the required module name):

'C:\Program Files\Universal\Python36\python.exe'
import pip
pip.main([‘install’,’requests’])

If you would like your script to automatically install any modules if they are not present, you can use the following example code in your script.

For example, if your Universal Task requires the “requests” module, you can use the following python code to install requests automatically if it is not already installed:

# -- Import requests, if error then install requests
try:
 import requests
except:
 try:
  from pip import main as pipmain
 except:
  from pip._internal import main as pipmain
 pipmain(
  [
    "install",
    "--trusted-host=pypi.python.org",
    "--trusted-host=pypi.org",
    "--trusted-host=files.pythonhosted.org",
    "requests",
  ]
 )
 import requests

This works for all platforms.
