环境：虚拟机Ubuntu20.04，vscode无法安装pycairo和PyGObject
虚拟机Ubuntu20.04，vscode中运行Anaconda搭建的vens 的Python3.8.10
首先在vscode中点击ctrl+shift+p，选择Python3.8.10的环境，自动激活Python
最近在搞无人机精准降落，网上下载的一段代码，总是报错，搞了三四天终于把环境搭好了
其中一段代码（如下）总是报错 ，原因就是没有wheel，然后pycairo和PyGObject安装不上去
import gi
gi.require_version("Gst", "1.0")
from gi.repository import Gst
报错先是：
ERROR: Could not build wheels for pycairo, which is required to install pyproject.toml-based projects
然后接着：
ERROR: Could not build wheels for PyGObject which use PEP 517 and cannot be installed directly
然后参考
- ERROR: Could not build wheels for PyGObject which use PEP 517 and cannot be installed directly #45
- ERROR: Could not build wheels for pycairo, which is required to install pyproject.toml-based projects
安装pycairo
新建Ubuntu终端，输入：
sudo apt-get install sox ffmpeg libcairo2 libcairo2-dev
sudo apt-get install texlive-full
完成以后，基本可以安装pycairo==1.21.0
在vscode的Python终端输入：
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pycairo==1.21.0
如果不行的话，先输入：
pip3 install manimlib # or pip install manimlib
pip3 install manimce # or pip install manimce
然后再次输入
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pycairo==1.21.0
安装PyGObject
新建Ubuntu终端输入：
sudo apt install libgirepository1.0-dev
然后在vscode输入
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple PyGObject==3.42.2
如下图：
笔者采用这种办法解决长久折磨我的问题，然后import gi 和Gst都不报错了，如果还是不成功，可以点进我参考的GitHub网址：https://github.com/gfduszynski/cm-rgb/issues/45
