谁能解释这里的错误是什么？

【参考方案1】：

看起来这个包是只为 Windows 开发的。

相关错误是这样的：

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 特定文件，包含在 Windows 开发 SDK 中。 见：

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

另外，如果你在 PyPi 上查看MetaTrader5 Release Files，你会发现只有 Windows 编译的***（-cp37-cp37m-win32、-cp37-cp37m- win_amd64），而不是像numpy（具有-linux-和-macos-）和Django（适用于-any- 平台）。

【讨论】：

您对此问题的解决方案是什么？ Vmware、docker 还是其他？

@BrenoPerucchi 我没有办法在非 Windows 机器上安装它。我的回答只是为了解决 OP 的问题，为什么它会在 Mac 上出错（以及如何检查它）。如果您的问题是如何在特定的非 Windows 机器上安装它，我建议您提出一个新问题。

【参考方案2】：

我不确定@gino-mempin 的答案，但他的答案在逻辑上似乎是正确的。这是导致我尝试失败的故事。 我将 Debian 10 Buster 与 Python3.7 一起使用。我曾尝试通过以下两种方式使用 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下载了包，正如上面提到的Gino，那里所有的***包，都有win32或win_amd64 前缀，这与我的架构不同。 所以这导致我根据我的架构类型更改文件名。为此，您应该首先在您的 python 中运行此代码，以使用您的 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')]

根据我默认的python3（cp37）版本，正确的架构是linux_x86_64所以我把文件名改成这样：

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

在更改文件名后，我通过以下命令安装了软件包，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，当我运行下面的代码时：

import MetaTrader5

我遇到了一个我还没有找到任何解决方案的错误：

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'

我希望这个问题出在我的系统上，至少这些步骤对你有用。如果不是，我认为 Gino 写的是正确的。

【参考方案3】：

在 Windows SO 中，您可以将目录 site-packages 放在 path 变量中。

我希望它对你有用；）
