我在/etc中检查了我的环境文件，并在那里设置了http_proxy变量.我不知道为什么我仍然会收到此错误.请有人指出吗?谢谢

I checked my environment file in /etc and the http_proxy variable is set there. I dunno why i'm still getting this error. Please could someone point out? Thanks

推荐答案

nltk已经从googlecode.com转移了，但网络上的大多数资源仍在继续提供参考.

nltk have shifted from the googlecode.com but still most of the resources on web continues to give its reference.

在第370行的"/usr/lib/python2.7/dist-packages/nltk/downloader.py"文件中从以下位置更新当前数据服务器设置:

update the current data server setting in "/usr/lib/python2.7/dist-packages/nltk/downloader.py" file on line 370 from:

DEFAULT_URL = 'http://nltk.googlecode.com/svn/trunk/nltk_data/index.xml'

到

DEFAULT_URL = "http://nltk.github.com/nltk_data/"
