Question

我剛剛收到了一份grunt包的副本，但是我是新手，我很難找到一些事情的答案。 最大的問題是不知道下面的錯誤來自哪里 - 有人能告訴我這是從哪里來的嗎？ 這兩個文件都在同一目錄中。

$ 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?

這是我的package.json：

    "srcDirectory": "./src",
    "srcJavascript": "./src/js",
    "srcCss": "./src/css",
    "srcData": "./src/data",
    "testDirectory": "./test",
    "tgtDirectory": "./build",
    "installDirectory": "../com/public/widgets",

  "devDependencies": {

    "grunt-contrib-cssmin": "~0.9.0",

  }
}

Answer 1

您可能沒有在本地安裝必要的軟件包。 嘗試npm install （ sudo npm install ）以確保你這樣做。

Answer 2

如果接受的答案不起作用且您有一個正確的package.json文件，您可以：

1. 刪除node_modules文件夾（或在某處備份）

2. 然后運行npm install

為了重新開始。

Answer 3

你必須告訴grunt在哪里找到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文件夾比Gruntfile高5級（查看setBase方法）。
