I’ve tried running dart2js both choosing “Run as JavaScript” from the context menu, and from Tools -> Generate JavaScript.

Both methods producing the same console output (an error):

Running dart2js...
No se esperaba \dart-sdk\bin\dart2js.snapshot en este momento.

Translated from Spanish would be:

Running dart2js...
Didn't expect \dart-sdk\bin\dart2js.snapshot at this moment.

I’m running Windows 7, 64 bits.

Dart Editor version 0.2.6_r15355

Dart SDK version 0.2.6.0_r15355

Note: I used to be able to run dart2js successfully, now I get that error.

Update: I’ve tried it with a nightly build and it worked well.

Per the comments above, try switching to a nightly build. Sorry for the bug. I assume it was a bug and that it’s fixed.
