python軟件包安裝時ImportError

Question

我正在完全按照docs http://django-wiki.readthedocs.io/en/latest/installation.html中的說明安裝django-wiki。

當我嘗試執行“ python manage.py migration”時，出現以下錯誤：

Traceback (most recent call last):

ImportError: cannot import name tokenTypes    

但是當我使用python shell導入它時...

>>> from html5lib.constants import tokenTypes
>>> print(tokenTypes)
{u'Comment': 6, u'StartTag': 3, u'EmptyTag': 5, u'Characters': 1, u'EndTag': 4, u'ParseError': 7, u'Doctype': 0, u'SpaceCharacters': 2}

...效果很好。

請，對此的任何幫助將是有用的！

問題是manage.py使用的是python解釋器以外的其他版本的html5lib 。 檢測到此錯誤的最簡單方法是直接轉到導致錯誤的軟件包文件，然后使用app.__version__打印出軟件包版本。 希望這對某人有幫助。
