gulp拋出一個錯誤：TypeError（'Path must be a string。Received'+ inspect（path））

Question

我正在使用節點v6.2.0。我有一個簡單的gulpfile來編譯ts文件並複製一些庫文件。

但是，當我嘗試複製庫，我不斷收到上述錯誤。

gulpfile.js：

const gulp = require("gulp"); 
const del = require("del"); 
const tsc = require("gulp-typescript"); 
const sourcemaps = require('gulp-sourcemaps'); 
const tsProject = tsc.createProject("tsconfig.json"); 
const tslint = require('gulp-tslint'); 
const config = require('./gulp.config.js'); 

const $ = require('gulp-load-plugins')({ 
    lazy: true 
}); 

// clean the contents of the distribution directory 
gulp.task('clean', function() { 
    return del(config.dest, { force: true }); 
}); 

gulp.task('resources', function() { 
    _log('copy - ' + config.assets, $.util.colors.yellow); 
    return gulp.src(config.assets, { base: root }) 
     .pipe(gulp.dest(config.dest)); 
}); 

/** 
* Copy all required libraries into build directory. 
*/ 
gulp.task("libs",() => { 
    _log('copying libs to:' + config.dest + 'lib' ,$.util.colors.yellow); 
    return gulp.src([ 
      'es6-shim/es6-shim.min.js', 
      'systemjs/dist/system-polyfills.js', 
      'systemjs/dist/system.src.js', 
      'reflect-metadata/Reflect.js', 
      'rxjs/**', 
      'zone.js/dist/**', 
      '@angular/**' 
     ], { cwd: 'node_modules/**' }) 
     .pipe(gulp.dest(config.dest + 'lib')); 
}); 

/** 
* Compile TypeScript sources and create sourcemaps in build directory. 
*/ 
gulp.task("compile",() => { 
    var tsResult = gulp.src(config.root + "**/*.ts") 
     .pipe(sourcemaps.init()) 
     .pipe(tsc(tsProject)); 
    return tsResult.js 
     .pipe(sourcemaps.write(".")) 
     .pipe(gulp.dest(config.dest)); 
}); 

gulp.task("default", ['compile', 'resources', 'libs'],() => { 
    _log('Building the project ...', $.util.colors.yellow); 

}); 

function _log(msg, color) { 
    color = color || $.util.colors.blue; 
    $.util.log(color(msg)); 
} 

function _logError(error) { 
    _log('**** START OF ERROR ***', $.util.colors.red); 
    _log(error, $.util.colors.red); 
    _log('**** END OF ERROR ***', $.util.colors.red); 

    return error; 
} 

gulp.config.js

module.exports = (function() { 
    var root = './'; 
    var config = { 
     root: root, 
     dest: '../dist/dashboard/', 
     assets: [ 
      root + 'assets/**/*.*', 
     ] 

    }; 

    return config; 
})(); 

錯誤堆棧：

你PROBL EM是這一行：

return gulp.src(config.assets, { base: root }) 

變量root沒有在你的gulpfile定義。 Node.js將其解釋爲對（不建議使用的）undocumented alias for global的引用。

你可能想：

return gulp.src(config.assets, { base: config.root })
