Undefined is not a function

[ivanjuras]

After updating node today I'm getting this error:

 TypeError: undefined is not a function

The line where the error occurs goes like this:

.pipe( critical({ ...

@ivanjuras looks like you're trying to use the stream method. This one isn't shipped yet and therefore only available in the master branch of critical . Are you sure you've got the right version?

[addyosmani]

@ivanjuras Are you using stable? (0.5.7) or master? As @bezoerb notes above, we'll need to know what version you're using in order to assist further.

I'm using 0.5.7. It seems to be something with Gulp Orchestrator:

Try with master npm install git+https://github.com/addyosmani/critical.git
stream isn't available in the stable version (0.5.7) yet.

@bezoerb Yep, it's working now. Thank you very much.

I'm seeing this issue now after updating to 0.6.0.

using this bit from the docs

gulp.task('critical', function () {
    return gulp.src('builds/*.html')
        .pipe(critical({base: 'builds/', inline: true, css:['builds/styles/components.css','builds/styles/main.css']}))
        .pipe(gulp.dest('builds'));
});

@johjacb do you also got this bit?
var critical = require('critical').stream;

[johjacb]
