我无法在docker上运行我的脚本，因为我无法运行#!/usr/bin/env python from time import sleep import datetime import os import shutil import cv2 import io import numpy as np import glob from threading import Thread import urllib2 import requests import json import boto3 import datetime，cv2，numpy和requests等模块。当我在终端上运行它时，它工作得很好，但是当我将它作为docker image运行时，它显示错误，没有任何模块命名...如何让它在我的docker上运行？

Dockerfile：

boto3

Answer 1

您可以运行容器：

docker run -it <image_name>

并在python控制台中执行以下命令，该命令将在容器中安装指定的包：

import os
os.system("pip install --upgrade pip")
os.system("pip install numpy requests boto3 opencv-python")

所以一切都好。我在使用FROM python:latest Dockerfile构建的容器中测试了它。

运行Docker镜像时出错。没有显示名为cv2，request，boto3的模块
