lib compilerOptions not used?

[jods4]

On the command line, my project compiles fine using:
tsc -p tsconfig.json
When using gulp-typescript 3.0 with TS 2.0, I get tons of comilation errors.

Apparently, TS does not know built-in objects such as Object, Function, RegExp, Promise, etc.
This should be covered by lib in my tsconfig options (and works on command line):

{
  "compilerOptions": {
    "target": "es6",
    "module": "amd",
    "outFile": "main.js",
    "allowJs": true,
    "lib": [ "dom", "es2017" ],
    "skipDefaultLibCheck": true,

    "noImplicitAny": true,
    "suppressImplicitAnyIndexErrors": true,
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true,
    "strictNullChecks": true,
    "noImplicitThis": true,
    "noImplicitReturns": true,
    "noUnusedLocals": true,
    "noFallthroughCasesInSwitch": true
  }
}

For reference, this is how I invoke gulp-ts:

const ts = require('gulp-typescript');
const tsProject = ts.createProject('App/tsconfig.json', { noResolve: true });

gulp.task('javascript', function () {
  const babel = require('gulp-babel');
  const gulpif = require('gulp-if');
  const sourcemaps = require('gulp-sourcemaps');

  return gulp.src(['**/*.ts', 'config.js'], { cwd: 'App' })
             .pipe(gulpif(options.sourcemaps, sourcemaps.init()))
             .pipe(tsProject())
             .js
             .pipe(babel({ presets: ['es2015-loose'], compact: true }))
             .pipe(gulpif(options.minify, uglify()))
             .pipe(gulpif(options.sourcemaps, sourcemaps.write()))
             .pipe(gulp.dest('wwwroot/dist'));
});

This looks like the same problem as microsoft/TypeScript#10678. Since you're only setting noResolve: true in your gulpfile, tsc doesn't have this option and works as expected.

@ivogabe I think you are correct, this is a TS bug.
I switched to noResolve from noExternalResolve in gulp-ts 2.x.
I guess I can remove it (for a perf hit) until TS is fixed.
