嗨，我正试图获得在虚拟环境中工作的特定版本的python
我尝试了这些解决方案:
https://askubuntu.com/questions/682869/how-do-i-install-a-different-python-version-using-apt-get
我没有编译答案，因为这样做看起来会摆脱我的"old"python的新版本。
所以我最关心的是第一个答案。我这样做了:
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt-get install python3.3
它似乎可以工作，虽然我没有得到一个"python3.3是安装的消息"或者不管它应该是什么样子:
sudo apt-get install python3.3

完成后，我期望python 3.3在usr/bin中可用，这样我就可以用它设置一个virtualenv，但它没有。我是不是漏了一步?
谢谢!
我发现3.3和我的ubuntu 20.04不兼容。我想因为我的python2.7工作，我可以直接升级到3.3没有问题。我猜只有2.7版本在那里，因为它是从旧的ubuntu遗留下来的。
无论如何，python3.5为我工作!
我假设你使用的是ubuntu 20.04
不幸的是，没有资金，我不能在20.04上提供python<3.5的包，因为这些版本从未收到libssl1.1补丁。我可以自己修补它们，但那是很多工作，我不能合理地做免费。所以在20.04版本中，你需要使用python3.5+
原因&;某事&;安装的是apt-get";很有帮助";将包名规范化为完全不相关的名称:
