找不到模块'corsheaders'django / heroku deploy

Question

没有其他答案对我有用。 我已经完成了pipenv install django-cors-headers ， pipenv install psycopg2-binary等操作，直到我的手指没有水泡...

如果您不介意的话，这会有点长。 提前致谢...

*settings.py*

# Application definition

INSTALLED_APPS = [
    'corsheaders',
    'rest_framework',
    'rest_framework.authtoken',
    'quizzes',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles'
] 


MIDDLEWARE = [
    'corsheaders.middleware.CorsMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.security.SecurityMiddleware',
    'whitenoise.middleware.WhiteNoiseMiddleware',
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

这是适当级别的Pipfile ...

[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[requires]
python_version = "3.6"

[packages]
python-decouple = "*"
"psycopg2" = "*"
django-dotenv = "*"
gunicorn = "*"
whitenoise = "*"
dj-database-url = "*"
djangorestframework = "*"
django = "*"
django-cors-headers = "*"
"psycopg2-binary" = "*"

[dev-packages]

但是我仍然从./manage.py获取回溯line 17行，最终没有名为“ corsheaders”的模块...我已经卸载/重新安装了所有东西。 任何人有任何想法吗？

我有一个类似的问题-尝试使用pip3 / pip / pipenv安装django-cors-headers 。 它为我解决了这个问题。
