MissingCorpusError: 
Looks like you are missing some required data for this feature.

To download the necessary data, simply run

    python -m textblob.download_corpora

or use the NLTK downloader to download the missing data: http://nltk.org/data.html
If this doesn't fix the problem, file an issue at https://github.com/sloria/TextBlob/issues.

解决方法：使用nltk下载

nltk.download()

下载过程中会有个弹窗，要自己选择下载的文件，在Models里第一个averaged_perceptron_tagger,然后点击下载，如果网络环境比较好的话，很快就可以下载完成了。

（2）翻译问题

    textblob 的翻译程序在 /usr/lib/python2.7/site-packages/textblob/translate.py

他主要是使用了google的翻译，代码中的链接为

url = "http://translate.google.com/translate_a/t"
