I am installing a python X module which is dependent on Y software.

There are two versions of Y software available, one that comes with operating system and another I installed it to a custom folder.

When I install "python X" module, I am asking it to take Y from my custom folder as a dependency.

The installation is successful, but while running that "python X" module as a application user then it is always taking Y ( it is making use of the libraries from Y) which is coming with operating system.

If we assume a.py is making use of "python X" module and

if I run

python a.py

then "python X" module is taking Y from my custom folder, but when I do

sudo -u user1 python a.py

then "python x" module is taking Y installed from operating system..

Could you let me know how to make "python x" module to always take from my custom folder for whichever user.

assume "from my custom folder", you may import "folder.module".

example :

#Test3.py
from Sub.Add2 import Add1 as SubAdd1
import Sub.Add2
import Add2

print( 'from Sub.Add2 import Add1 as SubAdd1, call SubAdd1 :' )
SubAdd1()

print( 'import Sub.Add2, call Sub.Add2.Add1(), Sub.Add2.Add2() :' )
Sub.Add2.Add1()
Sub.Add2.Add2()

print( "import Add2, call by 'object'.function name :" )
Add2.Add1()
Add2.Add2()

#Sub/Add2.py
def Add1():
    print( "Sub.Add2.py : Add1() ", 1 + 1 )

def Add2():
    print( "Sub.Add2.py : Add2() ", 2 + 2 )

Add2.py in current folder :

#Add2.py
def Add1():
    print( "Add2.py : Add1() ", 1 + 1 + 1 )

def Add2():
    print( "Add2.py : Add2() ", 2 + 2 + 2 )


> python Test3.py
from Sub.Add2 import Add1 as SubAdd1, call SubAdd1 :
Sub.Add2.py : Add1()  2
import Sub.Add2, call Sub.Add2.Add1(), Sub.Add2.Add2() :
Sub.Add2.py : Add1()  2
Sub.Add2.py : Add2()  4
import Add, call by 'object'.function name :
Add2.py : Add1()  3
Add2.py : Add2()  6

  • "python X" is a third party pure python package that has .py files but those .py files makes use of software Y which is not python – Kalyan Kumar Nov 12 '20 at 04:25
