docker中安装 python

安装python3.10.14

ubuntu 

1、安装源码编译所需依赖

apt-get update

apt-get install -y gcc g++ make libncurses5-dev libgdbm-dev liblzma-dev libz-dev libffi-dev libreadline-gplv2-dev tk-dev libc6-dev zlib1g-dev

apt-get install -y checkinstall libdb-dev libexpat1-dev libncursesw5-dev libreadline-dev libsqlite3-dev libssl-dev libtinfo-dev libbz2-dev build-essential

2、下载python安装包

 python-release安装包下载_开源镜像站-阿里云

3、解压安装 

ADD https://www.python.org/ftp/python/3.10.14/Python-3.10.14.tgz /usr/local/Python-3.10.14.tgz

RUN tar -zxvf Python-3.10.14.tgz && cd Python-3.10.14 
    && ./configure --prefix=/usr/local/python --enable-optimizations --with-ensurepip \
    && make -j4 && make install && cd ../ && rm -rf Python-3.10.14* \
    && apt-get autoclean && rm -rf /var/lib/apt/lists/*

4、设置环境变量

export LD_LIBRARY_PATH=${HOME}/python/lib:$LD_LIBRARY_PATH
export PATH=${HOME}/python/bin:$PATH

您也可以将以上命令写入~/.bashrc文件中，然后执行source ~/.bashrc命令使其立即生效。

 5、设置软链接

将python和pip3 软连接到/usr/local/bin目录下

ln -s  /usr/local/python3.10.9/bin/pip3.10  /usr/local/bin/pip3 

6、配置pip源 

mkdir ~/.pip
cd ~/.pip

vim pip.conf

[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
trusted-host = pypi.tuna.tsinghua.edu.cn
