Hello. Developing an application using Apache Cordova. There was a need to install the plugin. I do as it is written in the office of documentation

cordova plugin add cordova-plugin-dialogs 

In response, such an error

 (node:5060) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Failed to fetch plugin cordova-plugin-code-push@latest via registry. 

Probably this is either a connection problem or plugin spec is incorrect. Check your connection and plugin name / version / URL. Error: cmd: Command failed with exit code 1 Error output: npm ERR! Windows_NT 10.0.17134 npm ERR! argv "C: \ Program Files \ nodejs \ node.exe" "C: \ Program Files \ nodejs \ node_modules \ npm \ bin \ npm-cli.js" "install" "cordova-plugin-code-push @ latest" " --production "" --save "npm ERR! node v6.11.3 npm ERR! npm v3.10.10

I rummaged through a bunch of information, tried various variations of the installation of plug-ins - all confused.
