Clean Docker pip install 导致错误：这些包与需求文件中的哈希不匹配

Question

我的 Dockerfile 看起来像

FROM python:3.7-slim

# System setup
ENV USER app
ENV APP_DIR /home/app

RUN useradd -ms /bin/bash ${USER}

# System dependencies
RUN apt-get -y update
RUN apt-get install -y --no-install-recommends \
  build-essential \
  libffi-dev \
  libpq-dev

# Update pip
RUN pip3 install --upgrade pip setuptools --user --no-cache-dir
RUN pip3 install wheel --user --no-cache-dir

WORKDIR ${APP_DIR}

# App dependencies
COPY setup.py ${APP_DIR}/
RUN pip3 install --extra-index-url {url} -e ${APP_DIR}/.[test] --user

使用以下 docker-compose：

version: '3'
services:
  application-api:
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - "8000:8000"
    volumes:
      - ~/.config/appsecrets/secrets.yaml:/var/lib/appsecrets/app.yaml:ro
    environment:
      APP_LOG_LEVEL: INFO

并与以下 setup.py

from setuptools import setup

setup(
    name="context_manager",
    install_requires=[
        "gunicorn[gevent]==20.0.4",
        "nltk==3.4.5",
        "psycopg2==2.7.3.2",
        "pyyaml==5.1.2",
        "pyparsing==2.4.6",
        "sentry-sdk==0.14.0",
        "tldextract==2.2.2",
    ],
    extras_require={"test": ["pytest", "pytest-cov", "mock"]},
)

这导致以下错误

这刚刚开始，并且不会影响任何其他人尝试构建相同的图像。

我曾尝试与不--user和--no-cache-dir的所有PIP3安装命令，没有运气。docker 容器在没有任何缓存步骤的情况下运行。我在 Windows (Home) 上使用 Docker 版本 19.03.1。

关于可能是什么原因的任何想法？

Answer 1

正如 @Michael-Rigoni 建议的那样，尝试将 --no-cache-dir 添加到最终的 pip3 命令中。

RUN pip3 install --extra-index-url {url} -e ${APP_DIR}/.[test] --user --no-cache-dir

该命令可能会在临时文件夹中查找缓存的哈希值。对于遇到此错误的其他人来说，除了添加之外最常见的解决方法--no-cache-dir似乎是：

1. 在运行 pip 之前尝试使用 wget 下载库文件
2. 尝试在不使用 setuptools 的情况下运行安装过程
3. 尝试跑步python setup.py clean --all并可能python setup.py develop
