I recently updated my electronJS app to a higher version together with electron-builder. I have no issues running the app with "npm start", however when I try to build it using electron-builder I get the following error when running "npm run dist":

$ npm run dist

myapp@1.0.0 dist C:\Projects\myapp build

'build' is not recognized as an internal or external command, operable program or batch file. npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! myapp@1.0.0 dist: build npm ERR! Exit status 1 npm ERR! npm ERR! Failed at the myapp@1.0.0 dist script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
