Python 降级-开发者社区

Python 降级方法

使用 conda 降级 Python 版本

conda 是一个流行的包管理工具，可以方便地管理 Python 环境。通过 conda 可以创建新的环境并指定 Python 版本。

conda create -n py36 python=3.6 conda activate py36

使用 pyenv 降级 Python 版本

pyenv 是一个 Python 版本管理工具，允许在同一系统中安装多个 Python 版本并轻松切换。

pyenv install 3.6.8 pyenv global 3.6.8

使用 virtualenv 创建特定版本环境

virtualenv 可以创建隔离的 Python 环境，配合特定版本的 Python 解释器使用。

virtualenv -p /usr/bin/python3.6 venv source venv/bin/activate

直接安装旧版 Python

从 Python 官网下载所需版本的源代码或安装包，手动安装并配置环境变量。

wget https://www.python.org/ftp/python/3.6.8/Python-3.6.8.tgz tar xzf Python-3.6.8.tgz cd Python-3.6.8 ./configure --prefix=/usr/local/python3.6 make && make install
