Compilation faild with MinGW on Windows

Discription

$ pip install rtmidi
    ...
    D:\msys2-64\mingw64\bin\gcc.exe -mdll -O -Wall -DMS_WIN64 -D__WINDOWS_MM__= -DPK_WINDOWS=1 -If:\mypython\ms2mmleditor\.venv-mmlparser\include -ID:\Python38\include -ID:\Python38\include -c cpp_src\RtMidi.cpp -o build\temp.win-amd64-3.8\Release\cpp_src\rtmidi.o /EHsc
    gcc: error: /EHsc: No such file or directory
    error: command 'D:\\msys2-64\\mingw64\\bin\\gcc.exe' failed with exit status 1

Then I downloaded this package and modified setup.py:

$ pip download rtmidi
$ tar -xzvf rtmidi-2.3.4.tar.gz

elif OSNAME == 'Windows':
    define_macros = [('__WINDOWS_MM__', ''),
                     ('PK_WINDOWS', '1')]
    # library_dirs = ['C:\Program Files\Microsoft SDKs\Windows\v7.1\Lib']
    libraries = ['winmm', 'python34']
    # extra_compile_args = ['/EHsc']

(btw, I don't know why it is "python34")

$ tar -czvf rtmidi-2.3.4.tar.gz rtmidi-2.3.4
$ pip install rtmidi-2.3.4.tar.gz

This time I installed successfully, but got an ImportError:

Python 3.8.1 (tags/v3.8.1:1b293b6, Dec 18 2019, 23:11:46) [MSC v.1916 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import rtmidi
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "F:\mypython\ms2mmlEditor\.venv-mmlparser\lib\site-packages\rtmidi\__init__.py", line 1, in <module>
    from ._rtmidi import *
ImportError: DLL load failed while importing _rtmidi: 找不到指定的模块。

So I have no idea how to install pyrtmidi without MSVC.
