I just updated angular-cli (v1.1) and created a new project using ng new MyProj. Then I added and installed two dependencies to the project.json fi
ng new MyProj
I solved the problem removing types from tsconfig.app.json. This is the new configuration:
types
tsconfig.app.json
{ "extends": "../tsconfig.json", "compilerOptions": { "outDir": "../out-tsc/app", "module": "es2015", "baseUrl": "" }, "exclude": [ "test.ts", "**/*.spec.ts" ] }
