个性化Python3.9基础镜像压缩（多阶段构建）

sh 版本

alpine 版本存在很多问题，会有很多依赖缺失，很多人都哟类似的经验，建议还是不要以alphine为基础镜像会有很多问题

# 第一阶段：安装依赖项和构建Python环境
FROM python:3.9-alpine AS builder
COPY requirements.txt .
RUN apk add --no-cache build-base libffi-dev openssl-dev && \
    pip install --no-cache-dir --upgrade pip && \
    pip install --no-cache-dir -r requirements.txt
COPY ./pytrends /usr/local/lib/python3.9/site-packages/pytrends/


# 第二阶段：复制构建好的Python环境和需要的文件到运行镜像
FROM python:3.9-alpine

/bin/bash版本

FROM python:3.9-slim as builder

    pip install --no-cache-dir -r requirements.txt
COPY ./pytrends /usr/local/lib/python3.9/site-packages/pytrends/
