Ubuntu22.04安装pyenv

git clone https://github.com/pyenv/pyenv.git ~/.pyenv
cd ~/.pyenv && src/configure && make -C src
echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc
echo 'command -v pyenv >/dev/null || export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(pyenv init -)"' >> ~/.bashrc
. ~/.bashrc

pyenv 通过源码编译并切换用户级 Python 版本，不会替代系统 Python。不要删除发行版自带解释器，否则 apt 和系统工具可能无法运行。

配置下载镜像

vim ~/.bashrc
export PYTHON_BUILD_MIRROR_URL_SKIP_CHECKSUM=1
#export PYTHON_BUILD_MIRROR_URL=https://npm.taobao.org/mirrors/python/
export PYTHON_BUILD_MIRROR_URL=https://registry.npmmirror.com/-/binary/python/

安装必须的依赖

sudo apt-get install build-essential zlib1g-dev libffi-dev libssl-dev libbz2-dev libreadline-dev libsqlite3-dev liblzma-dev tk-dev

安装python3.7.8

pyenv install 3.7.8

切换python版本

pyenv local 3.7.8
pyenv global 3.7.8
