如何在Python 3中使用slugify？

Question

我正在尝试使用我安装的slugifypip3 install slugify.但是,在解释器中,如果我尝试敲击字符串,'hello'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.

IPython 5.1.0 -- An enhanced Interactive Python.

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)

     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.

object?   -> Details about 'object', use 'object??' for extra details.

In [1]: from slugify import slugify

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

如何在Python 3中使用它？

Answer 1

你安装的slugify包不是为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 unicode中不存在的python 2关键字.

你可能做到了:

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 ,它python-slugify在你安装时调用,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:您必须删除您安装的原始包,因为它们使用相同的名称.
