import path was wrong!!

[nxsre]

package sir/lib/errors: unrecognized import path "sir/lib/errors" (import path does not begin with hostname)
package sir/models: unrecognized import path "sir/models" (import path does not begin with hostname)
package sir/controllers: unrecognized import path "sir/controllers" (import path does not begin with hostname)

the import path in your way is in best practice，as temporary hack project we'll refactor this structure soon.

because our team is in a very very busy project developing, sooooorry for the late reply.
