Python [Errno 61]连接被拒绝

Question

我将这句话“ python -m textblob.download_corpora”输入终端（我使用Mac OS系统），终端显示：

[nltk_data] Error loading brown: <urlopen error [Errno 61] Connection
[nltk_data]     refused>
[nltk_data] Error loading punkt: <urlopen error [Errno 61] Connection
[nltk_data]     refused>

[nltk_data]     Connection refused>
[nltk_data] Error loading movie_reviews: <urlopen error [Errno 61]
[nltk_data]     Connection refused>

这是怎么了？有人可以帮忙吗？
