django - 下载 mysqlclient 时 Docker-compose 出错

问题描述

构建 docker-compose.yml 时出现此错误。我有一个 django 项目，当我尝试安装它的依赖项时，出现以下错误：

ERROR: Command errored out with exit status 1:

下载mysqlclient时弹出错误。

有人帮忙

docker-compose.yml 看起来像这样

version: '3.7'

services:
  db:
    image: mysql:5.6
    ports:
      - "3306:3306"
    environment:
      MYSQL_DATABASE: 'djangodatabase'
      MYSQL_USER: 'admin'
      MYSQL_PASSWORD: '12345'
      MYSQL_ROOT_PASSWORD: '12345'
  web:
    build: .
    command: python manage.py runserver 127.0.0.1:8000
    volumes:
      - .:/code
    ports:
      - "8000:8000"
    depends_on:
      - db

这是我的 Docker 文件：

FROM python:3.8-slim
ENV PYTHONBUFFERED 1
RUN mkdir /code
WORKDIR /code
COPY requirements.txt /code/
RUN pip install -r requirements.txt
COPY . /code/

解决方案

FROM python:3.7-slim
RUN apt-get update
RUN apt-get install -y gcc
RUN apt-get install -y default-libmysqlclient-dev
ENV PYTHONBUFFERED 1

RUN mkdir /code
WORKDIR /code

COPY requirements.txt /code/

RUN pip install -r requirements.txt

COPY . /code/

通过在我的 docker 文件中添加 default-libmysqlclient-dev 依赖项解决了这个问题。
