安装 pycairo 时遇到问题。关于下一步尝试什么有什么建议吗？

Question

我已经尝试安装 pycairo 三天了，我想知道是否有人可以重现该错误，或​​者我是否慢慢开始发疯。

\n

我尝试过的：

\n

我查看了Installation of PyCairo on Windows和How do you install PyCairo (Cairo for Python) on Windows?的答案。。

\n

我尝试使用从 Windows 的 Python 扩展包下载的文件安装 pycairo，但它显示\n ERROR: pycairo-1.19.1-cp38-cp38-win32.whl is not a supported wheel on this platform.\n我使用了以下命令pip install "C:\\Users\\...\\Downloads\\pycairo-1.19.1-cp38-cp38-win32.whl"

\n

我尝试通过 pip 安装 pycairo pip install pycairo，这给了我一个很长的错误消息：

尝试通过 pip 安装包含 pycairo 的PyGoject时，我收到相同的错误消息。

我发现了一些应该可以修复错误的东西，但不幸的是论坛中的链接已失效。我去了官方下载页面（我相信）cairgraphics.org，它也是一个死链接。

我尝试的另一件事：我在开始时去了开罗文档开罗文档，但不幸的是它仅适用于 Ubuntu/Linux/IOS。

我也遇到了与此类似的错误，所以这对我有用。请访问https://pycairo.readthedocs.io/en/latest/getting_started.html了解更多信息。在运行安装命令之前，您必须运行这五个命令之一来在计算机上设置 pkg-config。

• Ubuntu/Debian：sudo apt install libcairo2-dev pkg-config python3-dev
• macOS/自制软件：brew install cairo pkg-config
• 拱门Linux：sudo pacman -S cairo pkgconf
• 软呢帽：sudo dnf install cairo-devel pkg-config python3-devel
• 笔使用：sudo zypper install cairo-devel pkg-config python3-devel

然后运行： import cairo

希望有效！
