无效语法：在 python 2.6.6 中导入 TextBlob

Question

我已经安装了 Python 2.6.6

我从Here下载了textblob包

我使用以下命令安装了包

python setup.py install

在我的站点包中，我可以看到以下彩蛋

textblob-0.11.1-py2.6.egg

但是当我导入包时，它给了我以下错误

> from textblob import TextBlob
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.6/site-packages/textblob-0.11.1-py2.6.egg/textblob/__init__.py", line 9, in <module>
    from .blob import TextBlob, Word, Sentence, Blobber, WordList
  File "/usr/lib/python2.6/site-packages/textblob-0.11.1-py2.6.egg/textblob/blob.py", line 28, in <module>
    import nltk

    from nltk.collocations import *
  File "/usr/lib/python2.6/site-packages/nltk-3.2.1-py2.6.egg/nltk/collocations.py", line 38, in <module>
    from nltk.util import ngrams
  File "/usr/lib/python2.6/site-packages/nltk-3.2.1-py2.6.egg/nltk/util.py", line 1361
    d = {k: _default_to_regular(v) for k, v in d.items()}
                                 ^
SyntaxError: invalid syntax

这里有什么遗漏吗？

更新 1：

我成功安装了 textblob 0.8.4

安装 NLTK 2.0.5 时出现以下错误

命令：

python setup.py install

错误：

`Installed /usr/lib/python2.6/site-packages/distribute-0.6.21-py2.6.egg

Answer 1

nltk-3.2.1 不支持 Python 2.6（SyntaxError 是因为 dictionary comprehension was not yet introduced to Python until 2.7）。将 Python 升级到 2.7 或将 nltk 降级到 2.0.5：

pip install nltk==2.0.5

编辑：在研究了TextBlob 的setup.py 和CHANGELOG.rst 文件后，如果你决定不升级你的Python，你可能还need to downgrade TextBlob to 0.8.4 来避免nltk>=3.0 的依赖。

编辑 2：要解决 setuptools 错误，请改用 python distribute_setup.py。

编辑3：如果您安装了TextBlob <= 0.8.4，则不需要安装nltk。因为它包含 nltk 的供应商版本。
