mongo-connector无法启动以下错误:

两天前设置运行正常.从那以后我关闭了mongo连接器,mongo-db在后台运行.但我没有对mongo运行任何查询.

现在我尝试今天早上启动mongo-connector并且无法启动.

viki@viki-pc:~/Documents/elasticSearch$ mongo-connector -m localhost:27017 -t localhost:9200 -d /usr/local/lib/python2.7/dist-packages/mongo_connector/doc_managers/elastic_doc_manager.py

我试图用弹性搜索连接mongo.它在2天前工作正常.
