“在PythonAnywhere上托管基于Tornado的Python应用程序时出错，运行WSGI应用程序时出错

Question

我正在尝试从Python和Virus on Network库托管Mesa。 Mesa is using Tornado以可视化服务器上​​的图形。 According to PythonAnywhere，似乎不推荐使用“龙卷风”，因为它具有异步能力，但是当不使用异步功能时，它仍然可以工作。我是网络托管的初学者，我尝试了以下操作，但没有用。

run.py

virus_on_network.server import server

app_server = server

if __name__=='__main__':
    app_server.launch()

wsgi.py

import sys
path = '/home/ABC123/mysite/'
if path not in sys.path:
    sys.path.append(path)

import tornado.web
import tornado.wsgi
from run import app_server as app  # noqa

application = tornado.wsgi.WSGIApplication([
    (r"/", app),
])

我得到了一些东西，但是JavaScript部分似乎没有执行。我确实将D3.js文件添加到了根目录中。

这应该是它的外观

server.log

我觉得这几乎是成功的（我可能是错的，但是我对Web开发非常陌生。任何提示或建议将不胜感激。

如果我正确理解了设置，您也希望Tornado也提供静态文件；为此，您必须让它知道在哪里可以找到它们。试试：
