在GitHub操作中未在Windows上找到开罗

Question

我试图在Ubuntu、macOS和macOS上运行我的cairosvg测试套件，当我导入cairosvg库时，cairosvg版本失败了。

tests\test_svg_turtle.py:6: in <module>
    from cairosvg import svg2png
.tox\py\lib\site-packages\cairosvg\__init__.py:26: in <module>
    from . import surface  # noqa isort:skip
.tox\py\lib\site-packages\cairosvg\surface.py:9: in <module>
    import cairocffi as cairo
.tox\py\lib\site-packages\cairocffi\__init__.py:48: in <module>
    cairo = dlopen(
.tox\py\lib\site-packages\cairocffi\__init__.py:45: in dlopen
    raise OSError(error_message)  # pragma: no cover
E   OSError: no library called "cairo-2" was found
E   no library called "cairo" was found
E   no library called "libcairo-2" was found
E   cannot load library 'libcairo.so.2': error 0x7e
E   cannot load library 'libcairo.2.dylib': error 0x7e
E   cannot load library 'libcairo-2.dll': error 0x7e

文档说您需要安装C++和cairo。关于更多的细节，它建议遵循WeasyPrint文档。这意味着你需要安装GTK3。

我在GitHub操作中很少使用GTK3，那么如何安装GTK3呢？这就是cairosvg所需要的吗？

我已经使用以下命令安装了cairo：

conda install -c conda-forge cairo
