任何人都可以解释这里的错误是什么吗？

2 个答案:

答案 0 :(得分：0)

该软件包似乎是仅针对Windows开发的。

相关的错误是这样的：

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

文件sdkddkver.h是Windows开发SDK附带的Windows特定文件。
参见：

此外，如果您在PyPi上检查MetaTrader5 Release Files，则会看到只有Windows编译过的滚轮（ -cp37-cp37m-win32 ， -cp37- cp37m-win_amd64 ），而不是像numpy（具有 -linux-和 -macos-）和{{ 3}}（可在 -any-平台上使用）。

答案 1 :(得分：0)

我不确定@gino-mempin的答案，但从逻辑上看他的答案是正确的。在这里，这个故事使我进行了失败的尝试。 我在 Python3.7 中使用 Debian 10 Buster 。我曾尝试通过以下两种方式通过pip3安装MetaTrader5：

python3 -m pip install MetaTrader5

或

pip3 install MetaTrader5

不幸的是，每次都会引发错误：

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

我决定手动安装它，所以我从Pypi.org下载了该软件包，正如上面的Gino所述，那里的所有wheel软件包都具有 win32 或 win_amd64 前缀，这与我的体系结构不同。 因此，这导致我根据我的体系结构类型更改文件名。为此，您应该首先在python中运行以下代码，以使用python版本提取正确的代码：

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

对我来说，输出是：

[('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')]

根据我的默认版本的python3（cp37），正确的体系结构是 linux_x86_64 ，所以我像这样更改了文件名：

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

更改文件名后，我通过以下命令安装了该软件包，没有任何问题：

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

直到这里一切顺利。但是在编码区域中，当我运行以下代码时：

import MetaTrader5

我遇到一个错误，我目前尚未找到任何解决方案：

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'

我希望这个问题与我的系统有关，至少这些步骤对您有用。如果没有，我会认为 Gino 写的是正确的。
