Cloned handlebars.js repository under windows 10 64bit, node 4.2.1
Installed dependencies npm install
Ran grunt. Initially there was an error in jison. After changing the eol of handlebars.I to unix it worked.
Again ran grunt
Got the following error:
Running "test:bin" task
Fatal error: Command failed: C:\WINDOWS\system32\cmd.exe /s /c "./bin/handlebars -a spec/artifacts/empty.handlebars"
To run ./bin/handlebars file under windows is necessary to execute node ./bin/handlebars
