如何安装特定补丁号版本的 Python？

这这里的问题告诉我如何安装特定版本的 iexy

我想安装特定版本的 Python xyz - 例如 3.6.3 - 而 Ubuntu 18.04 中的默认版本是 Python 3.6.8。

有没有办法安装特定补丁号的 Python 版本？

我尝试了相关问题中选择的答案，但无法正确安装。

sudo apt install python3.6.3

E: Unable to locate package python3.6.3
E: Couldn't find any package by glob 'python3.6.3'
E: Couldn't find any package by regex 'python3.6.3'

我可以安装特定版本，但不能安装补丁号

sudo apt-get install libssl-dev openssl
wget https://www.python.org/ftp/python/3.5.0/Python-3.5.0.tgz
tar xzvf Python-3.5.0.tgz
cd Python-3.5.0
./configure
make
sudo make install

这有点晚了，但是你可以使用类似的工具，而不是自己从源代码安装pyenv来处理这个问题。例如：

pyenv install 3.9.8
pyenv local 3.9.8  # Activate Python 3.9 for the current project or
pyenv global 3.9.8  # Activate Python 3.9 globaly
