我尝试使用slugify,我使用pip3 install slugify安装了MKGeodesicPolyline。但是,在解释器中,如果我尝试对字符串'hello'进行细化,我会看到以下内容:

Python 3.5.2 (default, Nov 17 2016, 17:05:23) 
Type "copyright", "credits" or "license" for more information.

In [1]: from slugify import slugify

In [2]: slugify('hello')
---------------------------------------------------------------------------

----> 1 slugify('hello')

/usr/local/lib/python3.5/dist-packages/slugify.py in slugify(string)
     22 
     23     return re.sub(r'[-\s]+', '-',

     25                 re.sub(r'[^\w\s-]', '',
     26                     unicodedata.normalize('NFKD', string)

NameError: name 'unicode' is not defined

In [3]: slugify(u'hello')
---------------------------------------------------------------------------

NameError: name 'unicode' is not defined

相比之下,在Python 2中,后者确实有效:

Python 2.7.12 (default, Nov 19 2016, 06:48:10) 
Type "copyright", "credits" or "license" for more information.

In [1]: from slugify import slugify

In [2]: slugify(u'hello')
Out[2]: u'hello'

如何在Python 3中使用它?

slugify package you installed不是为python 3构建的,它目前只支持python 2.并且它不太可能会更新。最简单的方法之一就是在整个源代码中,它使用了python 2中不存在的python 2关键字unicode

你可能做过:

pip install slugify

这是一个过时的包,而不是你链接的包。

要安装你链接的slugify包https://pypi.python.org/pypi/python-slugify,安装它时称为python-slugify,它支持所有最新的python版本。并有更多的功能。

pip install python-slugify

并以与其他包相同的方式导入:

from slugify import slugify

注意:您必须删除已安装的原始包,因为它们使用相同的名称。

安装python-slugify
