我正在为Heroku上的Django应用程序寻找一个有效的uwsgi配置。
目前我有
uWSGI==1.4.4
和
requirements.txt# this is in a single line:
web: uwsgi --http-socket=$PORT --home=$HOME
--module="myapp.wsgi:application"
--master --vacuum --processes=1 --plugins=python
--virtualenv="/app/.heroku/python/"
中的。但这失败了：
Procfile我猜第二个错误（2013-01-15T11:48:17+00:00 app[web.1]: open("./python_plugin.so"): No such file or directory [core/utils.c line 4733]

）可能是第一个错误的结果（ImportError: cannot import name urandom）
该应用程序适用于默认的Django devel HTTP服务器。
任何想法如何解决这个问题？指向工作配置非常受欢迎。
