+## Limitations
+
+### Referencing local dependencies using a path in JavaScript projects
+
+Although dependency scanning doesn't support it, you can reference dependencies by using a
+[local path](https://docs.npmjs.com/files/package.json#local-paths) in the `package.json` for a
+JavaScript project. The dependency scan generates the following error when you use

+ERROR: Could not find dependencies: <dependency-name>. You may need to run npm install
