这是由于网络的问题，那么就换一个国内的镜像源头

pip3 install pymongo -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com

提示如下，下载是下载成功了，但是提示么有权限无法按照

安装成功后，程序运行出来
程序代码：

#!/usr/bin/python3
 
import pymongo
 
myclient = pymongo.MongoClient('mongodb://localhost:27017/')
 
dblist = myclient.list_database_names()
print(dbliist)

结果：

python3 test_mogondb.py 
['admin', 'config', '20190909', 'local']
