compass:dist & execFile("compass.bat", ...) - Warning: spawn EPERM

Question

First of all, I am pretty new to (modern) web development and I tried to import an existing project into my WebStorm and run a Grunt task.

It stops at "compass:dist" with:

Aborted due to warnings.

I tried googling a bit, but all I seem to get is that this is a permission error, but I don't know where to start to fix it.

I tried cleaning the project, reinstalling Ruby for Windows, reinstalling compass inside of ruby. Nothing worked.

Update:

I tried debugging the build and in file bin-version\index.js the line

execFile(bin, ['--version'], function (err, stdout, stderr) {

seems to throw the error as the debugger wouldn't go beyond this point. The bin is compass.bat and it looks like the build has some permission error? When I open my cmd and type "compass --version" it just works fine. I have the ruby/bin in my classpath aswell where the compass.bat is placed.

Does anyone know about what could cause this error?

Answer 1

I solved this, but I can't tell exactly what caused it. What I can say is that it has nothing to do with compass itself, wrong permissions or Windows - it has to do with a wrong project setup. So, if you get this error, check your setup and if every dependency is available.
