如何解决“模块”对象没有属性“_base”问题？

Question

我正在尝试运行位于此处的investopedia api：https://github.com/kirkthaker/investopedia-trading-api

我写了以下脚本：

from investopedia import *
client = Account("emailaddress","password")

status = client.get_portfolio_status()
print status.account_val
print status.buying_power
print status.cash
print status.annual_return

我能够通过为每个依赖项运行 py -2.7 setup.py install 来安装所有模块。

我收到以下错误：

Traceback (most recent call last):
File "C:/Users/Z/PycharmProjects/investopedia/test.py", line 1, in <module>
    from investopedia import *
  File "C:\Users\Z\PycharmProjects\investopedia\investopedia.py", line 4, in <module>
    from bs4 import BeautifulSoup
  File "C:\Users\Z\AppData\Local\Enthought\Canopy\User\lib\site-packages\bs4\__init__.py", line 29, in <module>
    from .builder import builder_registry
  File "C:\Users\Z\AppData\Local\Enthought\Canopy\User\lib\site-packages\bs4\builder\__init__.py", line 297, in <module>
    from . import _html5lib
  File "C:\Users\Z\AppData\Local\Enthought\Canopy\User\lib\site-packages\bs4\builder\_html5lib.py", line 57, in <module>
    class TreeBuilderForHtml5lib(html5lib.treebuilders._base.TreeBuilder):
AttributeError: 'module' object has no attribute '_base'

你知道如何解决这个问题吗？

Answer 1

使用 conda 解决了这个问题

conda install beautifulsoup4
conda install html5lib

Answer 2

通过使用解决了这个问题

pip2.7 install --upgrade beautifulsoup4
pip2.7 install --upgrade html5lib

现在效果很好。
