Ubuntu16.04上启动Spyder出现错误AttributeError: 'module' object has no attribute '_base'

＃首先安装安装Spyder
python2

sudo pip install spydersudo apt-get install python-pyqt*

python3

sudo pip3 install spydersudo apt-get install python3-pyqt*

＃ 如果成功安装后，打开Spyder时出现如下错误，解决方案如下：

class　TreeBuilderForHtml5lib(html5lib.treebuilders._base.TreeBuilder):
AttributeError: ‘module’ object has no attribute ‘_base’

解决方案：升级html5lib库至1.0b8 可以解决问题.

sudo pip install --upgrade html5lib==1.0b8
