Could anyone explain what the error here is stating?

Answer 1

It looks like the package was developed only for Windows .

The relevant error is this:

In file included from src/MetaTrader.cpp:6:
src/stdafx.h:16:10: fatal error: 'sdkddkver.h' file not found
#include <sdkddkver.h>

The file sdkddkver.h is a Windows-specific file that is included with the Windows development SDK.
See:

• What is sdkddkver.h?
• what is SDKDDKVer.h for?

Also, if you check the MetaTrader5 Release Files at PyPi, you'll see that there are only compiled wheels for Windows ( -cp37-cp37m-win32 , -cp37-cp37m-win_amd64 ), as opposed to other cross-platform packages like numpy (has -linux- and -macos- ) and Django (works on -any- platform).

Answer 2

I'm not sure about the answer of @gino-mempin but his answer logically seems correct. Here the story that leads me to have an unsuccessful attempts. I'm using Debian 10 Buster with Python3.7 . I had tried to install MetaTrader5 with pip3 in two ways as below:

python3 -m pip install MetaTrader5

or

pip3 install MetaTrader5

Unfortunately, an error raises each time:

Could not find a version that satisfies the requirement MetaTrader5 (from versions: )

I decided to manually install it, so I downloaded the package from Pypi.org and as Gino mentioned above, all the wheel packages over there, have win32 or win_amd64 prefixes which is different with my architecture. So this causes me to change the file name according to my architecture type. To do so, you should first run this code in your python to extract the proper one with your python version:

import wheel.pep425tags
print(wheel.pep425tags.get_supported())

For me the output was:

[('cp37', 'cp37m', 'linux_x86_64'), ('cp37', 'abi3', 'linux_x86_64'), ('cp37', 'none', 'linux_x86_64'), ('cp36', 'abi3', 'linux_x86_64'), ('cp35', 'abi3', 'linux_x86_64'), ('cp34', 'abi3', 'linux_x86_64'), ('cp33', 'abi3', 'linux_x86_64'),
 ('cp32', 'abi3', 'linux_x86_64'), ('cp37', 'none', 'any'), ('cp3', 'none', 'any'),
 ('cp36', 'none', 'any'), ('cp35', 'none', 'any'), ('cp34', 'none', 'any'), ('cp33', 'none', 'any'), ('cp32', 'none', 'any'), ('cp31', 'none', 'any'), ('cp30', 'none', 'any'), ('py3', 'none', 'linux_x86_64'), ('py37', 'none', 'any'), ('py3', 'none', 'any'), ('py36', 'none', 'any'), ('py35', 'none', 'any'), ('py34', 'none', 'any'),
 ('py33', 'none', 'any'), ('py32', 'none', 'any'), ('py31', 'none', 'any'), ('py30', 'none', 'any')]

According to my default version of python3 (cp37), the proper architecture is linux_x86_64 so I changed the filename like this:

MetaTrader5-5.0.29-cp37-cp37m-win_amd64.whl
to
MetaTrader5-5.0.29-cp37-cp37m-linux_x86_64.whl

After this change in filename, I've installed the package without any problem by this command:

python3 -m pip install MetaTrader5-5.0.29-cp37-cp37m-linux_x86_64.whl

Until here everything goes well. But in coding area, when I run the code below:

import MetaTrader5

I confront with an error that I couldn't find any solution for that yet:

ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-1-824b43c0d46a> in <module>
----> 1 import MetaTrader5

~/mt5/env/lib/python3.7/site-packages/MetaTrader5/__init__.py in <module>
    250 
    251 # import C methods to our module
--> 252 from ._core import *
    253 
    254 # internal order send

ModuleNotFoundError: No module named 'MetaTrader5._core'

I hope this problem is with my system and at least these steps works for you. If not, I would think what Gino wrote would be correct.

Answer 3

In Windows SO, you can put the directory site-packages inside path variable.

I hope that it is works for you ;)
