I´m doing it on visual studio

I have retried to make all the process thre times and always got the same

Some explanation: I´m doing this course using my first Atlas cluster from the Mongo Basic course, because when I try to make another new All of hte was of payment. Also I have already installed node.

Your course would have asked you to create the cluster with a specific name
I don’t think you can use m001 cluster.Only one cluster per project allowed
Create a new project and create your new cluster under it(mflix i think)

#3

I make the new project and reinstall every thing:
Now i got this error

PS C:\Users\pablo\Desktop\mflix-js> npm test -t db-connection

server@1.0.0 test
jest --passWithNoTests “db-connection”

“jest” no se reconoce como un comando interno o externo,
programa o archivo por lotes ejecutable.

If translation is needed:

“jest” is not recognize as internal o external command, program or executable batch file.

Hi @Pablo_Torre,
Try installing Jest as a dev dependency.

npm install --save-dev jest

Hopefully, it will fix the issue.

In case you have any doubts, please feel free to reach out to us.

I miss something during the installation?

I have to make a cuestion:
When I unzip m220/mflix-js.zip, it´s supposed that this unzips a few archives with some folders (README, build, .babelrc …) , or a single folder with these archives and folders (m220/mflis-js)?

#7

Hi @Pablo_Torre, yes it is the expected behavior, all the folders will appear wherever you unzip them.

If you have any doubts, please feel free to reach out to us.

Thanks and Regards.
