Question

通过“ docker-compose build”构建docker映像时出现以下错误。

ERROR: Couldn't connect to Docker daemon at http://127.0.0.1:2375 - is it running?

If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.

即使我尝试使用“ sudo”，我也得到了：

那是我的Dockerfile：

# pull official base image
FROM python:3.8.3-alpine

# set work directory
WORKDIR /usr/src/app

# set environment variables
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1

# install dependencies
RUN pip install --upgrade pip
COPY ./requirements.txt .
RUN pip install -r requirements.txt

# copy project
COPY . .

和docker-compose.yml：

version: '3.7'

services:
  web:
    build: .
    command: python manage.py runserver 0.0.0.0:8000
    volumes:
      - ./:/usr/src/app/
    ports:
      - 8000:8000
    env_file:
      - ./.env.dev

我要补充一点，我几个月前购买了笔记本电脑，并且在此设备上以前的系统上已经遇到了Docker问题（这是我更改系统的原因之一）。我从Fedora切换到Ubuntu。

此外，我的shell中没有python3的“ python”别名，并且由于未知原因，我需要在简单的“ pip冻结”之前放置“ python3 -m”。

我希望这些信息可能有用。谢谢。

。。

在我的Dockerfile中添加“ RUN apk add builder-base”后，出现以下错误：
