Windows上的cairosvg

Question

使用pip安装cairosvg后，我试图使其正常工作，但似乎无法使其正常工作。我不想安装MSYS2和GTK +，所以我希望库足够（我有Graphviz）。但是，这就是我得到的：

>>> import ctypes.util
>>> path = ctypes.util.find_library('libcairo-2')
>>> print(path)
c:\MyPrograms\graphviz\bin\libcairo-2.dll
>>> import cairosvg
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Users\U021586\AppData\Local\Programs\Python\Python36\lib\site-packages\cairosvg\__init__.py", line 41, in <module>
    from . import surface  # noqa
File "C:\Users\U021586\AppData\Local\Programs\Python\Python36\lib\site-packages\cairosvg\surface.py", line 24, in <module>
    import cairocffi as cairo
File "C:\Users\U021586\AppData\Local\Programs\Python\Python36\lib\site-packages\cairocffi\__init__.py", line 41, in <module>
    cairo = dlopen(ffi, 'cairo', 'cairo-2', 'cairo-gobject-2')
File "C:\Users\U021586\AppData\Local\Programs\Python\Python36\lib\site-packages\cairocffi\__init__.py", line 38, in dlopen
    raise OSError("dlopen() failed to load a library: %s" % ' / '.join(names))
OSError: dlopen() failed to load a library: cairo / cairo-2 / cairo-gobject-2

现在，此问题以前是here的问题，但从未得到正确回答。

有人可以帮忙吗？

谢谢！
