Question

我试图学习Gulp并且无法通过Task Run Explorer成功运行任务。没有任何任务出现，资源管理器显示错误：Failed to load, see output window for more information.检查输出窗口时，似乎无法找到我的project.json。

Failed to run "F:\Projects\NewInventory\src\NewInventory\Gulpfile.js"...

但是，我还从头开始创建了一个新的.Net5 Web应用程序，并与我当前的项目进行了比较，以确保project.json位于正确的目录位置。

我的project.json如下：

的package.json

Gulpfile.js

var gulp = require("gulp"),
    rimraf = require("rimraf"),
    concat = require("gulp-concat"),
    cssmin = require("gulp-cssmin"),
    uglify = require("gulp-uglify"),
    project = require("./project.json");

var bower = require('gulp-bower');
var del = require('del');
var project = require(' ./project.json');
var lib = project.webroot + '/lib';

var paths = {
    webroot: "./" + project.webroot + "/"
};

paths.js = paths.webroot + "js/**/*.js";
paths.minJs = paths.webroot + "js/**/*.min.js";

paths.minCss = paths.webroot + "css/**/*.min.css";
paths.concatJsDest = paths.webroot + "js/site.min.js";
paths.concatCssDest = paths.webroot + "css/site.min.css";

gulp.task('default', ['bower:install'], function () {
    return;
});

gulp.task('bower:install', ['clean'], function () {
    return bower({
        directory: lib
    });

gulp.task('clean', function (done) {

gulp.task("clean", ["clean:js", "clean:css"]);

gulp.task("min:js", function () {

        .pipe(cssmin())
        .pipe(gulp.dest("."));
});

gulp.task("min", ["min:js", "min:css"]);

您可以通过删除行来修复错误

var project = require(' ./project.json');

路径文字开头的空格意味着它没有指向project.json。在做你需要做的事情之前有一条线;

var gulp = require("gulp"),
    rimraf = require("rimraf"),
    concat = require("gulp-concat"),
    cssmin = require("gulp-cssmin"),
    uglify = require("gulp-uglify"),
    project = require("./project.json"); <---- This is doing what you expected.
