theia: Problems building Theia under Windows 10

I tried to build Theia under Window 10 with following setup:

• Node 8.0.0
• npm 4.5.0
• tsc 2.3.2
• GIT Bash : 2.10.0.windows.1

I pulled the newest version of Theia some minutes ago (2017-06-12).

I followed the steps in doc/Developing.md:

Everything worked fine until trying the examples:

First I tried example Browser: Step npm run bootstrap worked fine. Step npm start ended in missing dependencies

• concurrently
• webpack-dev-server
• bunyan
• webpack
• rimraf

And after installing these modules an error message was printed that the lib folder ist missing.

I tried then a npm run cold:start and got following error:

browser-example@0.0.1-alpha.1 lint D:\git_2\external\theia\examples\browser tslint -c …/…/config/tslint/tslint.json --project ./tsconfig.json

Warning: The ‘no-use-before-declare’ rule requires type checking

Tell the author that this fails on your system: npm ERR! tslint -c …/…/config/tslint/tslint.json --project ./tsconfig.json

I have no idea how to continue.

Then I tried the electron example: I had to install the electron module.

After running npm start I got a Windows error dialog with the message: Unable to find Electron app at D:\git_2\external\theia\examples\electron\lib\frontend\electron-main.js

Then I tried also npm run cold:start and got the same message as for the browser example:

$ npm run cold:start

How can I build Theia under Windows 10? Do I have to install different versions or what is wrong in my setup?
