将Playwright服务部署至AWS ECR时依赖安装失败的求助

问题原因 #

你使用的public.ecr.aws/lambda/python:3.8镜像基于Amazon Linux 2，而playwright install-deps默认会尝试调用Ubuntu的包管理工具apt-get，这就导致了apt-get: command not found的错误。

解决方案 #

方案1：指定系统类型执行Playwright依赖安装 #

修改Dockerfile中的playwright install-deps命令，加上--system amazon-linux参数，让Playwright适配Amazon Linux环境：

FROM public.ecr.aws/lambda/python:3.8

COPY requirements/prod.txt ${LAMBDA_TASK_ROOT}

RUN python3 -m ensurepip
RUN pip install -r prod.txt
RUN playwright install 
RUN playwright install-deps --system amazon-linux

ADD src ${LAMBDA_TASK_ROOT}

CMD ["main.handler"]

方案2：手动用yum安装依赖 #

如果方案1仍有问题，可以直接使用Amazon Linux的包管理工具yum手动安装Playwright所需的依赖：

FROM public.ecr.aws/lambda/python:3.8

COPY requirements/prod.txt ${LAMBDA_TASK_ROOT}

RUN python3 -m ensurepip
RUN pip install -r prod.txt
# 手动安装Amazon Linux 2环境下Playwright运行所需的系统依赖
RUN yum install -y atk cups-libs gtk3 libXcomposite libXcursor libXdamage libXext libXi libXrandr libXScrnSaver libXtst pango at-spi2-atk libXt alsa-lib libdrm mesa-libgbm nss nspr libuuid
RUN playwright install 

ADD src ${LAMBDA_TASK_ROOT}

CMD ["main.handler"]

注意事项 #

• 确保requirements/prod.txt中包含playwright以及你需要的浏览器包（如playwright-chromium、playwright-firefox等）
• 构建镜像时保证网络连接正常，若yum install超时可适当调整构建配置
