The error is probably because you are not in the directory where you have mongodb executable. There are two ways to do it.

1. change your directory to mongodb's installation path
2. Add the mongodb executable to your environment variables

Path should be something like

{installation_directory}:\\Program Files\\MongoDB\\Server\\{version}\\bin

For example C:\\Program Files\\MongoDB\\Server\\4.2\\bin
