Docker容器无法识别Django Formtools

问题描述 投票：0回答：1

我有一些使用Django表单工具的代码（特别是SessionWizardView）。从我所看到的，Formtools似乎在Docker Container之外工作，但在一个内部使用时失败。它正在发挥作用的环境。生产不受影响的Docker容器。

获得的错误消息是（在正在运行的容器的日志中）：

from formtools.wizard.views import SessionWizardView ModuleNotFoundError: No module named 'formtools'

**我已经安装了formtools

C:\Users\dgmufasa>pip install django-formtools
Requirement already satisfied: django-formtools in c:\work\software\python64bitv3.6\lib\site-packages
Requirement already satisfied: Django>=1.8 in c:\work\software\python64bitv3.6\lib\site-packages\django-1.11.7-py3.6.egg (from django-formtools)
Requirement already satisfied: pytz in c:\work\software\python64bitv3.6\lib\site-packages\pytz-2017.3-py3.6.egg (from Django>=1.8->django-formtools)

我已将它添加到settings.py文件中的INSTALLED_APPS

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',

     [..snip ..]

    'formtools',
]

我已将它用作程序的一部分：

from django.shortcuts import render, render_to_response
from formtools.wizard.views import SessionWizardView
#from django.contrib.formtools.wizard.views import SessionWizardView
from django.contrib.auth.decorators import login_required

[... snip ...]

在这个领域（开发）它一切正常 - 但是 - 当采用完全相同的代码，创建一个Docker文件并将其投入生产时，我得到了错误。

可以看到：收集django-formtools（来自-r requirements.txt（第6行））下载django_formtools-2.1-py2.py3-none-any.whl（132kB）

所以，看起来Docker正在收集它 - 但是 - 在运行代码时，

这是用于启动容器的内容：

docker-compose -f $ FILE_EXTRACTION / docker-compose.yml up --no-deps -d web_work 2>＆1

这是导致的错误（来自容器的日志）：

ModuleNotFoundError: No module named 'formtools'

为什么会这样？

开发机器上的Python（在Windows上）

C:\WORK\AppPython\ContractorsClubBackofficeCode>python --version
Python 3.6.3

Docker正在进行构建的Python（在Linux上）

python --version
Python 2.7.12

我想我可以尝试在Docker构建正在进行的机器上升级Python。你觉得那会有用吗？

Update

似乎Dockerbuild本身使用的是Python 3.6.2

下面是目前正在使用的Dockerfile（虽然，我将python版本更改为3.6.3以查看会发生什么）

当您在Docker文件中使用pip install时，您将安装Python 2的软件包。请改用pip3。

pip3 install -r requirements.txt

我认为你不需要COPY *.path线。一旦用pip3安装了所有需求，site-packages目录应包含它所需的一切。
