    Default Cannot get reactor-boilerplate started

    I have tried everything and i cannot get past the 2nd step (Creating a new application) in the Getting Started guide...

    I have posted a comment on this issue in github which seems very similar. Have a look there for the real details but essentially, when I run npm start it just hangs with the same error message each time...

    .....

    I'm almost certain this is caused by some issue with sencha-cmd (see here for more analysis and evidence). This is a real pity as I was so looking forward to ExtReact and I can't even get it started.

    The issue was indeed related to sencha-cmd. However, it was actually the JRE version which caused the error. Thanks to @israelroldan's suggested solution here.

    I upgraded Java to latest version (8), deleted node_modules/reactor-boilerplate folder (just to make sure I had a clean install) and then ran npm install followed by npm start. Everything worked perfectly this time.
