node.js - gulp 抛出错误 : TypeError ('Path must be a string. Received ' + inspect(path))

Question

我使用的是 Node v6.2.0。我有一个简单的 gulpfile，它编译 ts 文件并复制一些库。

但是当我尝试复制库时，我不断收到上述错误。

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;
})();

你的问题是这一行:

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

变量 root 未在您的 gulpfile 中定义。 Node.js 将此解释为对(已弃用)undocumented alias for global 的引用。 .

您可能想要:

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