Verify Project Configuration

Each project in SFDX requires an sfdx-project.json project configuration file.

Verify that the packageDirectories, namespace, and sourceApiVersion attributes are set.

1{ 
2  "packageDirectories": [ 
3    { 
4      "path": "my-pkg2-app", 
5      "default": true 
6    } 
7  ], 
8  "namespace": "acme_example", 
9  "sourceApiVersion": "41.0" 
10}

You can create the sfdx-project.json file by hand or copy the versions in the SFDX sample repositories as a starting point.
