Pyspider webui调试错误

Question

1.在Ubuntu上搭建好Pyspider环境后，用Pyspider all命令启动，然后在webui中单步调试测试时，遇到下面异常：

Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/pyspider/run.py", line 360, in <lambda>
    app.config['fetch'] = lambda x: webui_fetcher.fetch(x)
  File "/usr/local/lib/python2.7/dist-packages/pyspider/fetcher/tornado_fetcher.py", line 114, in fetch
    return self.async_fetch(task, callback).result()
  File "/usr/lib/python2.7/dist-packages/tornado/concurrent.py", line 129, in result
    raise_exc_info(self.__exc_info)
  File "/usr/lib/python2.7/dist-packages/tornado/gen.py", line 227, in wrapper
    runner.run()
  File "/usr/lib/python2.7/dist-packages/tornado/gen.py", line 531, in run
    yielded = self.gen.send(next)
  File "/usr/local/lib/python2.7/dist-packages/pyspider/fetcher/tornado_fetcher.py", line 136, in async_fetch
    result = self.handle_error(type, url, task, e)
TypeError: handle_error() takes exactly 6 arguments (5 given)

测试所用的python脚本是github上官方demo程序；然后又使用本人在Windows平台上已经测试能正常运行的程序，同样抛出以上异常

终端报错信息是：

[E 160817 11:00:53 tornado_fetcher:135] 'module' object has no attribute 'maybe_future'
Traceback (most recent call last):
    File "/usr/local/lib/python2.7/dist-packages/pyspider/fetcher/tornado_fetcher.py", line 127, in async_fetch
    result = yield gen.maybe_future(self.data_fetch(url, task))
    AttributeError: 'module' object has no attribute 'maybe_future'

本人测试的程序是：

from pyspider.libs.base_handler import *


class Handler(BaseHandler):
    crawl_config = {
    }

    @every(minutes=24 * 60)
    def on_start(self):
        self.crawl('http://scrapy.org/', callback=self.index_page)

    @config(age=10 * 24 * 60 * 60)
    def index_page(self, response):
        for each in response.doc('a[href^="http"]').items():
            self.crawl(each.attr.href, callback=self.detail_page)

    def detail_page(self, response):
        return {
            "url": response.url,
            "title": response.doc('title').text(),
        }

本人刚接触Pyspider，想研究源码但是心有余力不足，所以在这儿虚心向各位大神请教，望得到大神指点！

Answer 1

我在Github上提交问题后，Pyspider作者，Binux大神问我tornado版本，这个提醒了我，原tornado版本是3.2，于是我用命令

pip install -U tornado

升级了tornado版本，问题解决了，多谢足兆叉虫，您应该就是Binux吧？
