Linux 安装 python 指定版本--编译源码方式

自动化脚本：

 #!/bin/bash
 sudo apt-get update

 sudo apt-get install -y gcc make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev xz-utils tk-dev libffi-dev liblzma-dev

 sudo mkdir /etc/python3.7.1

 sudo wget -P /home/$USER https://www.python.org/ftp/python/3.7.2/Python-3.7.2.tgz 

 sudo tar zxvf  /home/$USER/Python-3.7..tgz -C  /home/$USER 

 sudo /home/$USER/Python-3.7./configure --enable-optimizations --prefix=/etc/python3.7.1 

 sudo make
 sudo make install

 sudo apt-get -y install python-pip python-virtualenv python-dev
 sudo virtualenv --python=/etc/python3.7.1/bin/python3 --no-site-packages --download /home/.pyenvs/myevn

根据需要修改文件中的 python 版本号，即可。

python 目录为：/etc/python3.7.1

虚拟目录为: /home/.pyenv/myenv

激活虚拟环境：source /home/.pyenvs/myenv/bin/activate

查看python 版本: python -V

退出虚拟环境：deactivate
