Apache 2在Django项目目录下找不到python软件包

标签： django python-3.x apache docker

我正在Ubuntu Docker容器中运行Apache2和Django。 Apache可以找到并正在尝试运行Django项目，但找不到在项目目录下包含的python软件包。它返回一个导入错误。见附图。

Django error message

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尝试在/ var / www / html / django_demo_app / INDmain / main / main / Lib / site-packages下查找请求包时，我遇到了同样的问题，因此我将目录添加到路径中，并且找到了Apache / Django包装。现在，它正在查找pandas软件包，但找不到位于同一目录中的依赖项numpy软件包。是什么原因导致Apache和/或Django无法看到这些软件包？

所以回答我自己的问题...

我不想在虚拟环境下运行此程序，因为Web应用程序是在此Docker容器中唯一运行的程序。因此，我在基本映像中安装了所有必需的python库软件包。我的Dockerfile，Requirements.txt和Docker组成文件如下。

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软件包解决了在Django和Apache的基础目录中找不到python模块的问题。为了使所有部分互相交谈，我们花费了大量的精力，因此希望这可以帮助其他有类似需求的人。
