在 Windows 上导入 `cairosvg` 时出错

Question

我使用的是 Windows (Windows 11)

我使用

cairosvg

安装了

pip

:

pip install cairosvg

但是当我导入它时出现此错误：

OSError: no library called "cairo-2" was found
no library called "cairo" was found
no library called "libcairo-2" was found
cannot load library 'libcairo.so.2': error 0x7e.  Additionally, ctypes.util.find_library() did not manage to locate a library called 'libcairo.so.2'
cannot load library 'libcairo.2.dylib': error 0x7e.  Additionally, ctypes.util.find_library() did not manage to locate a library called 'libcairo.2.dylib'
cannot load library 'libcairo-2.dll': error 0x7e.  Additionally, ctypes.util.find_library() did not manage to locate a library called 'libcairo-2.dll'

我尝试了很多修复，包括安装 GTK+ Runtime：

OSError: no library called "cairo-2" was found
no library called "cairo" was found
cannot load library 'C:\GTK+ Runtime\bin\libcairo-2.dll': error 0xc1
cannot load library 'libcairo.so.2': error 0x7e.  Additionally, ctypes.util.find_library() did not manage to locate a library called 'libcairo.so.2'
cannot load library 'libcairo.2.dylib': error 0x7e.  Additionally, ctypes.util.find_library() did not manage to locate a library called 'libcairo.2.dylib'
cannot load library 'C:\GTK+ Runtime\bin\libcairo-2.dll': error 0xc1

但是仍然有错误。

您可以使用以下方式安装 CairoSVG 2.7.1：

python -m pip install CairoSVG

确保您使用受支持的 Python 版本。根据文档：

当前版本的 CairoSVG 至少需要 Python 3.6，它不适用于 Python 2.x。旧版本的 CairoSVG (1.x) 可与 Python 2.x 配合使用，但不再受支持。 CairoSVG 及其依赖项在安装过程中可能需要其他工具：编译器、Python 标头、Cairo 和 FFI 标头。根据您使用的操作系统，这些工具有不同的名称。

请注意，在 Windows 上，您必须安装 Cairo（例如 GTK）和 Python 的 Visual C++ 编译器。
