gulp-dart's Issues

ENOENT error : dart is on my PATH and still errors

I installed the Dart SDK and added it to my path, can compile pages manually, but still receive the ENOENT error when using gulp.

I looked up other common causes of the ENOENT error and most say it's due to a clean task or similar but I do not have such a task that deletes any folders.

ENOENT error

Hello,
when trying to transpile dart to js I get this error:

events.js:85
throw er; // Unhandled 'error' event
            ^
Error: spawn dart2js ENOENT
  at exports._errnoException (util.js:746:11)
  at Process.ChildProcess._handle.onexit (child_process.js:1046:32)
  at child_process.js:1137:20
  at process._tickCallback (node.js:355:11)

My gulpfile is pretty simple:

gulp.task 'default', ->
    gulp.src files.source
    .pipe watch(files.source)   
    .pipe plumber()
    .pipe dart()
    .pipe gulp.dest files.destin

Thanks for any suggestion
