安装Spyder时，使用清华镜像加速并修改pip命令可避免长时间等待。然而，Spyder5.4.3版本可能消耗大量内存，4个Python进程可能导致886.89M的占用，对于8G内存的系统可能显得不足。文章提供了相关资源链接供参考解决这些问题。
安装Spyder，使用清华镜像，总是提示
INFO: pip is looking at multiple versions of sanic to determine which version is compatible with other requirements. This could take a while.
INFO: This is taking longer than usual. You might need to provide the dependency resolver with stricter constraints to reduce runtime. If you want to abort this run, you can press Ctrl + C to do so. To improve how pip performs, tell us what happened here: https://pip.pypa.io/surveys/backtracking
参考：https://blog.youkuaiyun.com/weixin_35757704/article/details/122269142，改为如下，很快安装完成！
pip3 install -U --user pip && pip3 install spyder -i https://pypi.org/simple
Spyder5.4.3 现在也很吃内存！Spyder+4个Python进程，占用了886.89M。
8G内存的机器不够看了！
