I have seen the following posts (- – -) but they are all related to classes that people have written themselves. I call a function from a ready library that works fine on Windows but fails on Linux.

I use MetaTrader5 in Ubuntu server 22.04 GUI to run a Python script as a trader bot.

My script worked on Windows definitely, however, when I ran the script on the Linux server I got this error:

TypeError: MetaTrader5.initialize() missing 1 required positional argument: 'self'

It’s the part of my script that caused this error:

from mt5linux import MetaTrader5 as mt5
mt5.initialize(login=111111, password='fjfklsfja', server = 'test-server')

this error has occurred even if I use the simple function on MetaTrader such as:

mt5.version()

Why does it get this error even though I have provided all the required parameters of the function? Even the simple function version, which has no input parameters, faces this problem.

Edit:

It’s an example of MetaTrader initialization in its documentation.

import MetaTrader5 as mt5
# display data on the MetaTrader 5 package
print("MetaTrader5 package author: ",mt5.__author__)
print("MetaTrader5 package version: ",mt5.__version__)
 
# establish MetaTrader 5 connection to a specified trading account
if not mt5.initialize(login=25115284, server="MetaQuotes-Demo",password="4zatlbqx"):
    print("initialize() failed, error code =",mt5.last_error())
    quit()

It works on Windows but fails in Linux.
