需要python版本python>=3.10

[xinmans]

可以做个docker

Dockerfile

FROM python:3.10
WORKDIR /app

COPY requirements.txt /app/requirements.txt

RUN pip install -r requirements.txt

CMD cd /app && scrapy crawl v2ex

docker-compose.yml

version: "3.7"
services:
v2ex_scrpay:
container_name: v2ex_scrpay
build: .
volumes:
- /usr/share/zoneinfo/Asia/Shanghai:/etc/localtime
- ./:/app/
restart: always

运行sudo docker-compose up -d即可

这个应用太简单了，加个Docker没必要

是的
但是我基础环境是python3.8版本的，换版本影响其他应用了

[oldshensheep]

Python有很多第三方的环境管理工具，可以用不同的Python版本。
