回答1:

See the picture

You should add an entry uri into your ./config/environment/.../database.json

uri should be mongodb://<host>:<port>/<database name>

回答2:

Please make sure your MongoDB is running with the settings you set in your ./config/environment/.../database.json

I think your host have ans issue, @ is not needed.

I suggest you to follow the Strapi doc about Mongo Atlas docs. That work with clusters. https://strapi.io/documentation/3.0.0-beta.x/guides/databases.html#install-on-atlas-mongodb-atlas

回答3:

1. Check is MongoDB instance is running
2. Check in the settings that host is correct: ./config/environment/.../database.json. Usually in development is localhost

回答4:

If you face this error while working with docker, Adding --network=host solves this problem. Keep in mind, use this solution only locally.

As described by docker itself,

--network="host" gives the container full access to local system services such as D-bus and is therefore considered insecure.
