grunt -未找到"Local Npm模块“xxx。是否已安装？”这是什么原因造成的？

Question

我刚刚收到了一份grunt包的副本，但我是个新手，在寻找一些问题的答案时遇到了困难。最大的问题是不知道下面的错误是从哪里来的--谁能告诉我这是从哪里来的？这两个文件都在同一个目录中。

$ grunt
>> Local Npm module "grunt-contrib-clean" not found. Is it installed?
>> Local Npm module "grunt-contrib-concat" not found. Is it installed?
>> Local Npm module "grunt-contrib-copy" not found. Is it installed?
>> Local Npm module "grunt-contrib-cssmin" not found. Is it installed?
>> Local Npm module "grunt-contrib-handlebars" not found. Is it installed?
>> Local Npm module "grunt-contrib-jshint" not found. Is it installed?
>> Local Npm module "grunt-contrib-qunit" not found. Is it installed?
>> Local Npm module "grunt-contrib-uglify" not found. Is it installed?
>> Local Npm module "grunt-preprocess" not found. Is it installed?
>> Local Npm module "grunt-wrap" not found. Is it installed?
>> Local Npm module "grunt-debug-task" not found. Is it installed?
Warning: Task "clean" not found.  Use --force to continue.

Aborted due to warning.

Answer 1

您可能还没有在本地安装所需的包。尝试npm install (sudo npm install)以确保您做到了这一点。

Answer 2

如果接受的答案不起作用，并且您有一个正确的package.json文件，您可以：

1. 删除node_modules文件夹(或将其备份到某个位置)
2. ，然后运行npm install

为了有一个新的开始。

Answer 3

你得告诉格鲁特哪里能找到node_modules。我的Gruntfile以：

module.exports = function (grunt) {
    // Tell grunt where to find node_modules
    grunt.file.setBase('../../../../../');
    grunt.loadNpmTasks('grunt-contrib-concat');
    grunt.loadNpmTasks('grunt-contrib-clean');
    grunt.loadNpmTasks('grunt-contrib-uglify');
    grunt.loadNpmTasks('grunt-contrib-copy');
    grunt.loadNpmTasks('grunt-hub');

在我的例子中，node_modules文件夹比Gruntfile高5级(看看setBase方法)。
