我正在尝试编写一个与MetaTrader5一起工作的Python算法。MT5是一个交易平台，用于交易外汇、股票等。
pip3 install MetaTrader5我得到了一个
命令“clang”失败，退出状态为1

看起来这个包是为开发的。
有关的错误是：
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中包含的一个特定于Windows的文件。
请参见：
另外，如果您查看MetaTrader5发布文件 at PyPi，您会发现只有编译好的PyPi(-cp37-cp37m-win 32，-cp37-cp37m-win_ and 64)，而不是其他跨平台包，如numpy (has和-macos-)和姜戈 (工作在任何平台上)。

我不确定@gino-mempin的答案，但他的回答在逻辑上似乎是正确的。在这里，这个故事导致我尝试失败。我正在使用Debian10Buster和Python3.7。我尝试用两种方式安装MetaTrader5和pip3，如下所示：
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下载了这个包，正如上面提到的，那里的所有车轮包都有win32或win_amd64前缀，这与我的体系结构不同。因此，这会导致我根据架构类型更改文件名。要做到这一点，您首先应该在您的python中运行以下代码，以提取适合您的python版本的代码：
import wheel.pep425tags
print(wheel.pep425tags.get_supported())对我来说，产出是：
[('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，正确的体系结构是linux_x86_64，因此我将文件名更改如下：
MetaTrader5-5.0.29-cp37-cp37m-win_amd64.whl
to
MetaTrader5-5.0.29-cp37-cp37m-linux_x86_64.whl在文件名更改之后，我已经安装了这个包，这个命令没有出现任何问题：
python3 -m pip install MetaTrader5-5.0.29-cp37-cp37m-linux_x86_64.whl在此之前一切都很顺利。但是在编码领域，当我运行下面的代码时：
import MetaTrader5我遇到了一个错误，我还没有找到任何解决办法：
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和至少这些步骤为您工作。如果不是，我认为吉诺写的是正确的。

在Windows中，您可以将目录site-packages放入路径变量中。
我希望这是适合你的;)
