"Failed to resolve module" in response

Question

In this case, I need it request-promise, but when I start to respond to my own project, I get an error:

"Unable to resolve module x. If you are sure the module is there, try restarting the packager."

This error is reported according to each depending requeston request-promise. I restarted the packer and also uninstalled node_modulesand reinstalled. In general, what happens in this error and in concrete, what can be done to solve it?

node v4.2.1, npm v2.14.7
