postgresql - 将 Web2py 部署到 Heroku(Psycopg2 错误)

Question

我正在尝试在 heroku 上部署一个 web2py 应用程序，虽然它在我的本地服务器上运行良好，但我在部署它时总是收到相同的票证。我坚持了一段时间，尝试了几个论坛的这个和那个解决方案。请帮忙!

Traceback (most recent call last):
 File "/app/gluon/restricted.py", line 217, in restricted
  exec ccode in environment
 File "/app/applications/processos/models/db.py", line 21, in <module>
  db = get_db(name=None, pool_size=10)
 File "/app/gluon/contrib/heroku.py", line 25, in get_db
  db = DAL(os.environ[name], pool_size=pool_size)
 File "/app/gluon/dal.py", line 7787, in __init__
  raise RuntimeError("Failure to connect, tried %d times:\n%s" % (attempts, tb))
RuntimeError: Failure to connect, tried 5 times:
Traceback (most recent call last):
 File "/app/gluon/dal.py", line 7766, in __init__
  self._adapter = ADAPTERS[self._dbname](**kwargs)
 File "/app/gluon/dal.py", line 2756, in __init__
  if do_connect: self.find_driver(adapter_args,uri)
 File "/app/gluon/dal.py", line 795, in find_driver
  raise RuntimeError("no driver available %s" % str(self.drivers))
RuntimeError: no driver available ('psycopg2',)

我在 Mac OSX 10.9.2 上运行

您的项目需要使用带有 pip 的 virtualenv。在部署之前，您需要在项目根文件夹中执行 pip freeze > requirements.txt。 Heroku 会查找此文件并相应地安装您的要求。 Heroku 的文档一般都很好。请引用Getting started with python寻求更多帮助。
