我正在尝试使用slugify,我使用pip3 install slugify
安装了它。但是,在解释器中,如果我尝试将字符串'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.

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'
我怎样才能让它在 Python 3 中工作?
你安装的slugify包不是为python 3构建的,它目前只支持python 2。而且它不太可能得到更新。最简单的判断方法是,在整个源代码中,它使用了python 2关键字unicode
,而python 3中不存在它。
你可能做到了:
pip install slugify
这是一个过时的软件包,而不是您链接的软件包。
要安装您链接的slugify软件包,https://pypi.python.org/pypi/python-slugify,当您安装它时,它被称为python-slugify
,它支持所有最新的python版本。并具有更多功能。
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软件包,因为它们使用相同的名称。
安装 python-slugify
pip install python-slugify
