如何修复 ModuleNotFoundError：没有名为“rest_auth”的模块

Question

我在虚拟环境中使用 docker 和 pipenv，运行 docker-compose up 时出现以下错误：

ModuleNotFoundError: No module named 'rest_auth'

我尝试了 pip install django-rest-auth 和 pipenv install django-rest-auth 并将以下内容添加到我的 INSTALLED_APPS

    # Django REST Framework Apps
    'rest_framework',
    'rest_framework.authtoken',
    'rest_auth',

INSTALLED_APPS = [
    "django.contrib.admin",
    "django.contrib.auth",
    "django.contrib.contenttypes",
    "django.contrib.sessions",
    "django.contrib.messages",
    "django.contrib.staticfiles",
    # Other Package Apps
    "storages",
    # Django REST Framework Apps
    'rest_framework',
    'rest_framework.authtoken',
    'rest_auth',
    # Internal Apps
    "authentication",

]

预计在 localhost:8000 上运行 docker 容器并访问后端

实际：docker-compose up > ModuleNotFoundError: No module named 'rest_auth'

Dockerfile：

FROM python:3.7

ENV PYTHONUNBUFFERED 1

RUN apt-get update -y && \
    apt-get install -y postgresql postgresql-contrib && \
    apt-get clean

RUN mkdir /code
WORKDIR /code
ADD . /code/

RUN pip install pipenv
RUN pipenv install --system

Answer 1

我遇到了同样的错误并这样做了：

首先我做到了：

pip 卸载 django-rest_auth

然后：

pip3 安装 django-rest_auth。

希望这行得通。
