Universal build crashes because of .ts source files

[wnabil]

when i am trying to import the module and run the universal build i got this error
ERROR in ./~/ng2-file-drop/module/file-drop.module.ts Module build failed: Error: Typescript emitted no output for /home/orange/Desktop/projects/maker/cli-universal-demo/node_modules/ng2-file-drop/module/file-drop.module.ts. You should not need to recompile .ts files in node_modules. Please contact the package author to advise them to use --declaration --outDir. More https://github.com/Microsoft/TypeScript/issues/12358 at Object.loader (/home/orange/Desktop/projects/maker/cli-universal-demo/node_modules/ts-loader/dist/index.js:32:15) @ ./dist/ngfactory/src/app/app.server.module.ngfactory.ts 150:11-59 @ ./src/server.ts
the problem as i expect is that the package contains the .ts source files and they must not be inside the module package on the npm.
but if i try to delete them manually the application also crashes because the ng2filedropmodule is declared inside the ts files.
version : 1.1.0
angular version : 4.1.0
webpack : 2.2.0
example repo : https://github.com/evertonrobertoauler/cli-universal-demo
run npm install ng2-file-drop
and include it inside whitelist array inside webpack.config
import the module inside app.module

Looking at the latest build, the .js script file is present - does this error still happen with v5.0.0?
