Gulp angular2 错误

Question

我在使用 .gulp at .netCore

部署 angular 项目时遇到错误

Package.json

"dependencies": {
    "@angular/common": "~2.1.0",
    "@angular/compiler": "~2.1.0",
    "@angular/core": "~2.1.0",
    "@angular/forms": "~2.1.0",
    "@angular/http": "~2.1.0",
    "@angular/platform-browser": "~2.1.0",
    "@angular/platform-browser-dynamic": "~2.1.0",
    "@angular/router": "~3.1.0",
    "@angular/upgrade": "~2.1.0",
    "@angular/angular-in-memory-web-api": "~0.1.5",
    "@angular/angular-cli": "1.0.0-beta.19-3".
    ... }

Gulp 错误信息

搜索此问题后，根据 angular-cli ticket，它似乎与 angular-cli 有关。票据上说它已从 beta15 开始修复，因此我添加了最新的 angular-cli 版本 beta.19-3。但是，gulp 仍然显示此错误，我不确定是否需要以不同的方式引用 angular-cli 以使其工作。我使用 gp_uglify 和 gp_uglify_harmony 尝试了两种不同的方法。但是我仍然有同样的错误。

gulpfile.js（任务）

gulp.task('app', ['app_clean'], function (cb) {
    pump([
        gulp.src(srcPaths.app),
        gp_sourcemaps.init(),
        gp_typescript(require('./tsconfig.json').compilerOptions),
        //gp_uglify({ mangle: false }),
        minifier(options, gp_uglify_harmony),
        gp_sourcemaps.write('/'),
        gulp.dest(destPaths.app)
    ],
    cb
    );
});

好像缺少一些选项，我也找到了这些帖子，参考了一个懒惰的选项，但我坚持使用它的方式$ Is not defined scripts Gulp task and gulp-load-plugins not loading plugins

如果有人遇到类似问题，最好的办法是使用日志记录，这通常会找到问题的根源

// Compile, minify and create sourcemaps all TypeScript files 
// and place them to wwwroot/app, together with their js.map files.
gulp.task('app', ['app_clean'], function (cb) {
    pump([
        gulp.src(srcPaths.app),
        gp_sourcemaps.init(),
        gp_typescript(require('./tsconfig.json').compilerOptions),
        gp_uglify({mangle:false}).on('error', gutil.log),
        gp_sourcemaps.write('/'),
        gulp.dest(destPaths.app)
    ],
    cb
    );
});
