我正在尝试第一次将非常简单的Django应用部署在AWS Lightsail实例上。我预配置了一个用bitnami和django设置的AWS Apache实例，并成功地遵循了tutorial，但没有虚拟环境，但是此后花了很多时间尝试用虚拟环境添加我自己的项目。
大多数事情似乎都正确设置，并且我可以很好地启动Apache，只能通过浏览器导航到我的URL，并在错误日志中找到ModuleNotFoundError: No module named 'requests'错误。这是我的代码中所有pip安装的模块的首次导入，因此建议我的虚拟环境尚未将其放入我的PYTHONPATH中。我只是通过硬编码站点软件包的路径并在我的wsgi.py文件中使用sys.path.append(...)附加路径来找到一种解决方案，但我认为这不是用Django应用程序配置am_wsgi的正确方法，并且担心以后会导致意外问题。
服务器上的所有django项目都位于/opt/bitnami/apps/django/django-projects/。在教程之后，该目录包含项目“ Project”和“ tutorial”。为了从这些项目中分离出requirements.txt文件和虚拟环境env，我决定在自己的文件夹中找到我的项目（一个非常简单的种族平等相关应用程序）。我怀疑此文件夹结构对我的问题至关重要：
django-projects/
Project/
tutorial/
re_app/
env/ # this is the virtual environmnent
requirements.txt
racial_equity_project/
conf/
httpd-app.conf
httpd-prefix.conf
db.sqlite3
manage.py
racial_equity_app/
urls.py
views.py
...
racial_equity_project/
settings.py
urls.py
wsgi.py
...
我希望这个httpd-app.conf文件可以工作。 python-home声明似乎与docs一致。
