目前，我正在部署我的Django应用程序，但是我收到了一个错误“django.core.exceptions.加载psycopg 2模块时出错：没有名为“psycopg 2”的模块“
我安装了psycopg 2和psycopg 2-binary在windows上的virtualenv中，但错误仍然存在。禁用了Django collectstatic（env var DISABLE_COLLECTSTATIC），因为这是psycopg 2的另一个错误。我需要在ubuntu VM中部署吗？
这是我的数据库引擎。我的DATABASE_URL =“Heroku_postgres link”。我错过了什么吗？
