Typescript编译器找不到几个npm软件包（gulp-typescript）

Question

I'm using gulp-typescript to compile my typescript files. It works but it doesn't find external modules like "@angular/core" . How can I configure TSC to look for these modules in node_modules?

PS: I'd like to bundle the typescript files with systemJS. Maybe I can somehow include the systemjs-config so that TSC knows where too look?

CODE:

gulp.task('tsc:release_dist', function() {
    return gulp.src(releaseBuildDest+'/**/*.ts')
        .pipe(gulpIgnore('node_modules/**'))
        .pipe(debug())
        .pipe(tsc({
            noImplicitAny: true,
            out: 'bundle.js',
            module: 'system'
        }))
        .pipe(gulp.dest(releaseBuildDest));
});

my project structure:

.dist/
..../release/
......./app/ (angular2 components, ...)
......./assets/ (css, img, ...)
......./node_modules/ (angular2 and other dependencies)
.......index.html
.......main.ts
.......systemjs.config.js

console output

how my components are requiring these packages:

import { NgModule } from '@angular/core';

tsconfig.js

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "moduleResolution": "node",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "lib": [ "es2015", "dom" ],
    "noImplicitAny": true,
    "suppressImplicitAnyIndexErrors": true
  }
}

Additional information: Everything works fine when I compile the regular dev build using "npm start" which is a shortcut to tsc -p src/. But I'm trying to build a "release build" gulp-task with bundled files. But If I copy everying to my release build directory and try to compile with tsc I get these errors shown above.

Try to set up your gulp typescript to use tsconfig information about your project. It might help. Below is an example that works for me just fine. Remove sourcemaps related parts if you do not need them.

var ts = require('gulp-typescript');
var gulp = require('gulp');
var sourcemaps = require('gulp-sourcemaps');

gulp.task('build.js.dev', () => 
{
    var tsProject = ts.createProject('tsconfig.json');

    var tsResult = tsProject.src()
        .pipe(sourcemaps.init())   
        .pipe(tsProject()); 

        //Write definitions 
        //tsResult.dts.pipe(gulp.dest(TEMP_TARGET_FOLDER)),
        //Write compiled js
    return tsResult.js.pipe(sourcemaps.write(
            ".", 
            { 
                includeContent: true, 
                sourceRoot: __dirname + "/dist"
            })).pipe(gulp.dest(TEMP_TARGET_FOLDER));
});
