ImportError：无法导入名称'错误'

与Tornado一起使用sockjs。在服务器上运行，这是返回的跟踪：ImportError：无法导入名称'错误'

python server.py

你能尝试在requirements.txt文件固定版本'sockjs，龙卷风== 1.0.3'？ – hurturk

@zatta：我安装了v1.0.3，同样的错误。 – moaglee

@McGrady：我没有安装asyncio。 – moaglee

我会建议你Python版本升级到的Python 3.5+和利用PEP-492异步又名/ AWAIT。如果您在使用Python 3.4，请更换与产量和等待异步DEF与@coroutine例如：

@asyncio.coroutine def coro(...): ret = yield from f()

从aiohttp文件建立：

async def coro(...): ret = await f()

应代之以

依赖关系 Python 3.4.2+

chardet，multidict，async_timeout，yarl

可选您可以安装cChardet和aiodns库（强烈推荐给速度的缘故）。

$ pip install cchardet

$ pip install aiodns
