Debian系统安装python
EMR集群机器需要一个镜像，需要在Debian系统上安装Python
以下是安装python3.7.13的过程，踩了一些坑，搜了几篇大佬的博客顺利解决
1.在编译安装之前，我们需要先安装一些 Python 依赖包，参考文献
以下是Debian需要安装的，一定要提前安装，要不会各种报错
#/bin/bash
PYTHON_DEPS="zlib1g-dev \
libbz2-dev \
liblzma-dev \
uuid-dev \
libssl-dev \
libreadline-dev \
libncursesw5-dev \
libsqlite3-dev \
libffi-dev \
libgdbm-dev \
tk-dev
"
for i in ${PYTHON_DEPS}
do
sudo apt-get -y install ${i}
done
echo ${?}
2.安装并编译python
tar xvf Python-3.7.13.tar.xz
cd Python-3.7.13
./configure --prefix=/usr/local/python3.7/ --enable-optimizations
make && make install
1.设置默认python
ln -s /usr/local/python3.7/bin/python3.7 /usr/bin/python
ln -s /usr/local/python3.7/bin/pip3.7 /usr/bin/pip
如果已存在，换成-sf
