AttributeError: 'SqliteDatabase' object has no attribute 'drop_table'

Ubuntu 16.04 LTS

$yd -s /path/to/my/dict

Traceback (most recent call last):
File "/usr/local/bin/yd", line 9, in

File "/usr/local/lib/python2.7/dist-packages/youdao-0.3.2-py2.7-linux-x86_64.egg/youdao/main.py", line 165, in main

db.drop_table(Word, fail_silently=True)
AttributeError: 'SqliteDatabase' object has no attribute 'drop_table'

Workaround:
由于是全新安装，没有旧 db，所以：
修改 "/usr/local/lib/python2.7/dist-packages/youdao-0.3.2-py2.7-linux-x86_64.egg/youdao/config.py"
注释掉 db.drop_table(Word, fail_silently=True) 这一行
