Apache 2 在 Django 项目目录下找不到 python 包

Question

我在 Ubuntu Docker 容器中运行 Apache2 和 Django。 Apache 可以找到并尝试运行 Django 项目，但找不到项目目录下包含的 python 包。它返回一个导入错误。见附图。

ImportError at / Missing required dependencies ['numpy'] Request Method: GET Request URL: http://localhost:8005/ Django Version: 2.1.7 Exception Type: ImportError Exception Value:
Missing required dependencies ['numpy'] Exception Location: /var/www/html/django_demo_app/INDmain/Lib/site-packages/pandas/__init__.py in <module>, line 19 Python Executable: /usr/bin/python3 Python Version: 3.6.7 Python Path:
['/var/www/html/django_demo_app/INDmain', '/var/www/html/django_demo_app/INDmain/Lib/site-packages', '/var/www/html/django_demo_app/INDmain/Scripts', '/usr/lib/python36.zip', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', '/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages', '/var/www/html/django_demo_app/INDmain', '/var/www/html/django_demo_app/INDmain', '/var/www/html/django_demo_app/INDmain/main']

当 Apache/Django 试图在 /var/www/html/django_demo_app/INDmain/main/Lib/site-packages 下找到请求包时，我遇到了同样的问题，所以我将目录添加到路径中，发现 Apache/Django包裹。现在它正在查找 pandas 包，但找不到位于同一目录中的依赖 numpy 包。什么可能导致 Apache 和/或 Django 看不到这些包？

所以回答我自己的问题...

我不想在虚拟环境下运行它，因为 Web 应用程序是唯一在这个 Docker 容器中运行的东西。因此，我在基础镜像中安装了所有需要的 python 库包。我的 Dockerfile、requirements.txt 和 Docker compose 文件如下。

Dockerfile

FROM ubuntu

RUN apt-get update && apt-get upgrade -y && apt-get dist-upgrade -y && apt-get autoremove -y && apt-get autoclean -y
RUN apt-get install -y apt-utils vim curl apache2 apache2-utils
RUN apt-get -y install python3 libapache2-mod-wsgi-py3
RUN ln /usr/bin/python3 /usr/bin/python
RUN apt-get -y install python3-pip
RUN ln /usr/bin/pip3 /usr/bin/pip
ADD ./requirements.txt .
RUN pip install -r requirements.txt

ADD ./web_site.conf /etc/apache2/sites-enabled/000-default.conf
ADD ./INDmain /var/www/html/INDapp/INDmain
EXPOSE 80 3500
CMD ["apache2ctl", "-D", "FOREGROUND"]

requirements.txt

django
ptvsd
requests
pandas
openpyxl
xlrd

docker-compose.yml

version: "2"

services: 
  ind-web-app-ubuntu:
    image: ind-web-app-ubuntu
    container_name: ind-web-app-ubuntu
    ports:
      - '8005:80'
      - '3500:3500'
      - '8006:81'
    restart: always

在现有的 python 环境中安装 python 包解决了在 Django 和 Apache 的底层目录中找不到 python 模块的问题。让所有部分相互交流需要付出巨大的努力，因此希望这将有助于其他有类似需求的人。
