今天使用python2安装es模块时报错：

You are using pip version 8.1.2, however version 23.0 is available.You should consider upgrading v_python

 

 

原因是pip(模块管理工具)版本过低，需先升级pip，再进行安装

先替换pip的镜像，默认镜像拉取慢，还可能会失败

cd ~;mkdir .pip;touch .pip/pip.conf
cat >> ./.pip/pip.conf <<'EOF'
[global]
index-url = https://mirrors.aliyun.com/pypi/simple/
[install]
trusted-host=mirrors.aliyun.com
EOF

再进行升级

python -m pip install --upgrade pip==20.3.4

最后安装es

python -m pip install elasticsearch
