linux源码编译安装Python3.9.6及pip

linux源码编译安装Python3.9.6及pip

1. 卸载之前的python

   sudo apt remove python3 
   sudo apt autoremove
   

2. 安装依赖

   sudo apt update
   sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev libsqlite3-dev wget libbz2-dev
   

3. 下载源码包

   cd /opt
   sudo wget https://www.python.org/ftp/python/3.9.6/Python-3.9.6.tgz
   tar -xzvf Python-3.9.6.tgz
   

4. 编译安装

   cd Python3.9.6/
   
   ./configure --prefix=/usr/local/python3  # pip3使用ssl
   
   #编译
   make
   
   #安装
   sudo make install
   

5. 设置python新路径

   ln -s /usr/local/python3/bin/python3 /usr/bin/python3
   

6. 安装pip

   sudo apt-get install python-pip
   

7. 设置pip路径

   ln -s /usr/local/bin/pip /usr/bin/pip
   

8. 查看版本

python --version

###Python 3.9.6

pip --verion

###pip 21.1.3 from /usr/local/python3/lib/python3.9/site-packages/pip (python 3.9)

9.设置环境变量
在家目录创建(.bash_profile): vim ~/.bash_profile

#配置python
export PYTHON_HOME=/usr/local/python3
export PATH=$PYTHON_HOME/bin:$PATH

执行source ~/.bash_profile命令使配置生效
