automation - automated script to install python package over a proxy? -

-

would possible write little python script automatically install needed python library import if needed library wasn't installed?

currently using

try:     import xlrd #library iterate through excel docs except importerror:     raise importerror('xlrd not installed, use "sudo pip install xlrd"\n')

but more automated.

as mentioned in comments setup.py approach 1 , quite easy.

beyond if need install dependencies across multiple servers suggest have @ solution http://www.ansible.com/home or https://puppetlabs.com/

as one-off can too:

ssh user@yourserver.com 'pip install xlrd'

edit - following on comments:

once have created setup.py specifying dependency on xlrd have run on every machine want install app. in order checkout automation tool advised above.

you that's dirty:

try:     import xlrd #library iterate through excel docs except importerror:     subprocess import call      call(["pip", "install", "xlrd"])
