打开终端，输入:

mongo 

下面的命令应该显示列出的数据库:

show dbs 

/* the <dbname> is the database you'd like to drop */
use <dbname> 

/* the below command will delete the database */
db.dropDatabase()  

终端输出如下:

{
  "dropped": "<dbname>",
  "ok": 1
}

使用python删除MongoDB数据库:

import argparse

import pymongo


if __name__ == "__main__":
    """
    Drop a Database.
    """

    parser = argparse.ArgumentParser()
    parser.add_argument("--host", default='mongodb://localhost:27017',
                        help="mongodb URI [default: %(default)s]")
    parser.add_argument("--database", default=None,
                        help="database name: %(default)s]")

    args = parser.parse_args()

    client = pymongo.MongoClient(host=args.host)

    if args.database in client.list_database_names():
        client.drop_database(args.database)
        print(f"Dropped: '{args.database}'")
    else:
        print(f"Database '{args.database}' does not exist")

在终端执行:

mongo // To go to shell

show databases // To show all existing databases.

use <DATA_BASE> // To switch to the wanted database.

db.dropDatabase() // To remove the current database.

登录到mongoDB命令行: 并键入下面的命令。 使用“YOUR_DATABASE_NAME”; db.dropDatabase ();

打开终端，输入:

mongo 

下面的命令应该显示列出的数据库:

show dbs 

/* the <dbname> is the database you'd like to drop */
use <dbname> 

/* the below command will delete the database */
db.dropDatabase()  

终端输出如下:

{
  "dropped": "<dbname>",
  "ok": 1
}

为了确保你放弃了正确的数据库使用

mongo <connection properties> --eval "db.getSiblingDB('dbname').dropDatabase()" 

在尝试保存到mongodb时，请参阅身份验证失败以了解问题。
