我将 Grunt 用作构建工具（惊喜），并将grunt-contrib-copy其用作调试和早期开发工具。我已经多次搜索了我的代码，但我不明白为什么会出现错误。这是我的代码。

Gruntfile.js

module.exports = function(grunt) {
    grunt.initConfig({
        pkg: grunt.file.readJSON('package.json'),
        concurrent: {
            watch: {
                options: {
                    logConcurrentOutput: true
                },
                tasks: ['watch:css', 'watch:html', 'watch:js', 'watch:img']
            }
        },
        watch: {
            css: {
                files: ['./src/scss/*.scss'],
                tasks: ['sass', 'autoprefixer']
            },
            js: {
                files: ['./src/js/*.js'],
                tasks: ['copy:js']
            },
            html: {
                files: ['./src/html/*.html'],
                tasks: ['copy:html']
            },
            img: {
                files: ['./src/img/*'],
                tasks: ['copy:img']
            }
        },
        sass: {
            files: {
                expand: true,
                cwd: './src/scss/',
                src: ['*.scss'],
                dest: './src/no-prefix-css',
                ext: '.css'
            }
        },
        autoprefixer: {
            options: {
                browsers: ['all']
            },
            files: {
                expand: true,
                cwd: './src/no-prefix-css',
                src: ['*.css'],
                dest: './build/css/',
            }
        },





        // Affected code
        copy: {
            html: {
                files: {
                    expand: true,
                    cwd: './src/html/',
                    src: ['*.html'],
                    dest: './build/html/'
                }
            },
            js: {
                files: {
                    expand: true,
                    cwd: './src/js/',
                    src: ['*.js'],
                    dest: './build/js/'
                }
            },
            img: {
                files: {
                    expand: true,
                    cwd: './src/img/',
                    src: ['*.bmp', '*.jpg', '*.jpeg', '*.svg', '*.png'],
                    dest: './build/img/'
                }
            }
        }
    });

    grunt.loadNpmTasks('grunt-contrib-watch');
    grunt.loadNpmTasks('grunt-contrib-sass');
    grunt.loadNpmTasks('grunt-contrib-copy');
    grunt.loadNpmTasks('grunt-autoprefixer');
    grunt.loadNpmTasks('grunt-concurrent');

    grunt.registerTask('default', 'Run build tools', ['concurrent:watch']);
}

这是我运行时的输出grunt copy:html -v

虽然这不起作用：

    copy: {
        buildImages: {
            files: {
                    expand: true,
                    cwd: paths.dev.cssImages,
                    src: '**/*',
                    dest: paths.prod.cssImages,
                    filter: 'isFile'
                }
        },
        buildBlub: {
            files: {
                    expand: true,
                    cwd: paths.dev.cssImages,
                    src: '**/*',
                    dest: paths.prod.cssImages,
                    filter: 'isFile'
                }
        }
    }

..这确实：

    copy: {
        buildImages: {
            files: [
                {
                    expand: true,
                    cwd: paths.dev.cssImages,
                    src: '**/*',
                    dest: paths.prod.cssImages,
                    filter: 'isFile'
                }
            ]
        },
        buildBlub: {
            files: [
                {
                    expand: true,
                    cwd: paths.dev.cssImages,
                    src: '**/*',
                    dest: paths.prod.cssImages,
                    filter: 'isFile'
                }
            ]
        }

    }

“文件”只需要一个对象数组，如果只给出一个复制任务，为什么它可以与单个对象一起工作..没有线索:)

我不确定为什么会这样，但对于那些有类似问题的人来说，这就是我的代码有问题的地方：

复制不允许我在其中创建子对象，就像我认为所有 Grunt 命令都允许的那样。为了解决我的问题，我将代码更改为如下所示：

copy: {
    default: {
        files: [
        {
            expand: true,
            cwd: './src/html/',
            src: ['*.html'],
            dest: './build/html/'
        },
        {
            expand: true,
            cwd: './src/js/',
            src: ['*.js'],
            dest: './build/js/'
        },
        {
            expand: true,
            cwd: './src/img/',
            src: ['*'],
            dest: './build/img/'
        }]
    }
}

显然复制需要一个子对象，但它不能处理多个。如果有人可以提供此功能的原因，我将非常高兴。似乎这可能被认为是一个错误grunt-contrib-copy，或者我的发现不正确。而且我也不喜欢。
