I am following Node.js tutorials by Code Academy from Youtube and am currently on video number 19. There you can see at 3:10 he typed mongo and then it switched to the database.
我正在关注来自 Youtube 的 Code Academy 的 Node.js 教程，目前正在播放第 19 号视频。在那里你可以看到在 3:10 他输入了 mongo，然后它切换到了数据库。
But in my case its giving the following error 'mongo' is not recognized as an internal or external command, operable program or batch file.Why is this happening?
但在我的情况下，它给出了以下错误'mongo' is not recognized as an internal or external command, operable program or batch file.为什么会发生这种情况？
I followed the steps exactly as shown in the video. To throw a light, in my case, its connected to the database and 2 documents are inserted (as shown). But in next step its giving this error. Please help me devs.
我完全按照视频中显示的步骤操作。举个例子，在我的例子中，它连接到数据库并插入了 2 个文档（如图所示）。但在下一步它给出了这个错误。请帮助我开发人员。

You have to add the mongo executable to PATH, so the commands are accessible from outside the MongoDB bin folder.
您必须将 mongo 可执行文件添加到 PATH，以便可以从 MongoDB bin 文件夹外部访问这些命令。
Search for your MongoDb installation bin folder and copy the path (e.g.: C:\Program Files\MongoDB\bin) Right click My Computer > Properties > Advanced system settings > Environment Variables > System variables > Look for "Path" > Edit > New > Paste in the path to your Mongodb bin folder > Restart your terminal
搜索您的 MongoDb 安装 bin 文件夹并复制路径（例如：C:\Program Files\MongoDB\bin）右键单击我的电脑 > 属性 > 高级系统设置 > 环境变量 > 系统变量 > 查找“路径”> 编辑 > 新建> 粘贴到你的 Mongodb bin 文件夹的路径 > 重启你的终端
EDIT:
编辑：
A faster way to get to the Environment Variables is to press Start on Windows and type "env"and then select "Edit environment variables"or "Edit system variables". No need really, to set the Path system wide if you don't have the privileges.
访问环境变量的更快方法是在 Windows 上按“开始”并键入“env”，然后选择“编辑环境变量”或“编辑系统变量”。如果您没有权限，则无需真正设置 Path 系统。

As some have stated, the path of mongo from version 4.0 changed a little: C:\Program Files\MongoDB\Server\4.0\bin
正如一些人所说，mongo 从 4.0 版开始的路径发生了一些变化：C:\Program Files\MongoDB\Server\4.0\bin

If you use Windows you need to add mogo (C:\Program Files\MongoDB\Server\4.0\bin) to PATH Env then close terminal and open again.....mongo --version should work
如果您使用 Windows，则需要将 mogo (C:\Program Files\MongoDB\Server\4.0\bin) 添加到 PATH Env 然后关闭终端并再次打开.....mongo --version 应该可以工作

First of all , "mongo" is not a node.js module.
首先，“mongo”不是 node.js 模块。
'mongo' is not recognized as an internal or external command, operable program or batch file.
This error is because your system doesnt recognize the command "mongo"
此错误是因为您的系统无法识别命令“mongo”
If you want to connect to database from terminal/cmd, check that the database path is included in your environment variable and then run command "mongo", or open the directory where mongodb is installed and access it from there
如果您想从终端/cmd 连接到数据库，请检查您的环境变量中是否包含数据库路径，然后运行命令“mongo”，或者打开安装 mongodb 的目录并从那里访问它
