我在'pythonanywhere'上实现了我的Django应用程序但是当我尝试在日志中加载我的网站时，我看到以下信息：
2019-02-27 20:20:37,677: Error running WSGI application
2019-02-27 20:20:37,678: ImportError: No module named 'crispy_forms'

当然，我在里面安装了一个虚拟环境和'crispy_forms'。什么可以触发此错误？当我在Bash PythonAnywhere中运行python3 manage.py runserver命令时，服务器正确启动。但是在日志中，错误仍然可见，页面基本不起作用。
任何帮助将不胜感激。

您确定在正确的环境中安装了包吗？
在通过bash为虚拟环境安装软件包之前，必须将其激活：
# activate the virtualenv, adapt the path if necessary:
source /home/zen404/.virtualenvs/zen404.pythonanywhere.com/bin/activate
# checkout if the python executable is from your virtualenv
which python
# THEN install your package - for the activated virtual env
pip install --upgrade django-crispy-forms
