安装pycairo有什么建议吗？

Question

我已经试着安装pycairo三天了，我想知道是否有人可以重现这个错误，或者我是否正在慢慢地变得疯狂。我很高兴得到任何帮助或建议

我所尝试的： 我看了来自Installation of PyCairo on Windows和How do you install PyCairo (Cairo for Python) on Windows?的答案

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

我试图通过pippip install pycairo安装Pyairo，这会给我一条很长的错误消息：

我在尝试通过pip安装包含pycairo的PyGoject时收到相同的错误消息

我发现了一些应该修复错误的东西，但不幸的是forum中的链接已经死了。我去了官方下载页面（我相信）cairographics.org，它也是一个死链接

编辑：我忘了提到我试过的另一件事，我去了the Cairo Docs on getting started，但不幸的是，它只适用于Ubuntu/Linux/IOS

Answer 1

我也遇到了与此类似的错误，下面是对我有效的方法。有关详细信息，请转到https://pycairo.readthedocs.io/en/latest/getting_started.html。在运行install命令之前，您必须运行这五个命令中的一个来在计算机上设置pkg config

• Ubuntu/Debian:sudo apt install libcairo2-dev pkg-config python3-dev
• macOS/Homebrew:brew install cairo pkg-config
• Arch Linux:sudo pacman -S cairo pkgconf
• 软呢帽：sudo dnf install cairo-devel pkg-config python3-devel
• 铅笔：sudo zypper install cairo-devel pkg-config python3-devel

然后运行： import cairo

希望能成功

Answer 2

我是Python新手，所以我不确定到底发生了什么，但这对我来说很有用。 只需将“pip”更改为“pip3”，它就会神奇地工作。 在撰写本文时，我使用的是Python 3.8 64位，因此我的命令如下：

pip3 install pycairo-1.19.1-cp38-cp38-win_amd64.whl

据我所知，这似乎是一种不兼容，因为Python2的生命已经结束，并在今年年初失去了支持。所以，几乎所有的教程都过时了，不起作用
