Your gulpfile:
Include your gulpfile, or only the related task (with ts.createProject).

var paths = {
    source: {
        config: './tsconfig.json'       
    },
    build: {
        config: path.join('dist', argv.app, 'config'),
    }
}
gulp.task('transpile:env', function () {

    var tsProject = tsc.createProject(paths.source.config);

    var envfile = env.is.production() ? 'env.config.prod.ts' : 'env.config.dev.ts';
    envfile = 'config/' + envfile;

    var sourcefiles = [envfile];
    var tsResult = gulp.src(sourcefiles)
        .pipe(tsc(tsProject(),tsc.reporter.defaultReporter()));
    return tsResult.js
        .pipe(concat('env.config.js'))
        .pipe(gulp.dest(paths.build.config));
});

tsconfig.json

Include your tsconfig, if related to this issue.

Looks like a duplicate of #449. Upgrading to version 3.1.1

[ivogabe]

Sorry, that's not the case.

[ivogabe]

The problem is in the following expression: tsc(tsProject(),tsc.reporter.defaultReporter()). You're now passing a stream (namely tsProject()) as the compiler options object. You should write this as tsProject(tsc.reporter.defaultReporter()). When you change that line, everything should be working fine.

[pkapare]

Perfect! That fixed those errors. I got confused with "Revised API of main function" at http://dev.ivogabe.com/gulp-typescript-3/ which says : The first argument options accepts either an object with compiler options, or a 'project', created by ts.createProject.

[ivogabe]

The old API was tsc(tsProject) (not tsc(tsProject())), which has been replaced by tsProject(). I'll update the post since accepts should be accepted.
