database - 为什么即使在成功导入 240 个文件后，总计数仍为零？

问题描述

实际上我正在学习 MongoDB，因为我被卡住以导入 JSON 文件（位于我笔记本电脑的桌面）

我的 JSON 文件是由 240 个元素组成的数组，每个元素的类型都相似，如下所示（我在数组中添加了两个这样的文档，类似地，其他 238 个具有相同形式的文档存在于同一个数组中）：-

我也尝试使用此命令：-

C:\Users\adity>mongoimport --jsonArray --db movie --collection movies --file C:\Users\adity\Desktop\tv-shows.json

我认为数据已经成功导入，因为我得到了这个

C:\Users\adity>mongoimport --jsonArray --db movie --collection movies --file C:\Users\adity\Desktop\tv-shows.json
2021-09-29T12:43:37.247+0530    connected to: mongodb://localhost/
2021-09-29T12:43:37.288+0530    240 document(s) imported successfully. 0 document(s) failed to import.

但是当我运行以下命令时，它向我展示了一些非预期的输出：-

C:\WINDOWS\system32>net start mongoDB

The MongoDB Server (MongoDB) service was started successfully.

The server generated these startup warnings when booting:

        Enable MongoDB's free cloud-based monitoring service, which will then receive and display
        metrics about your deployment (disk utilization, CPU, operation statistics, etc).

        The monitoring data will be available on a MongoDB website with a unique URL accessible to you
        and anyone you share the URL with. MongoDB may use this information to make product
        improvements and to suggest MongoDB products and deployment options to you.

        To enable free monitoring, run the following command: db.enableFreeMonitoring()
        To permanently disable this reminder, run the following command: db.disableFreeMonitoring()

我正在使用 Windows 操作系统。

有人可以帮助我为什么我将 count 的值设为零吗？
