Fail to copy lib file for lodash!

Done.

以下是我的Gruntfile.js的外观

module.exports = function(grunt) {
  var _ = require("lodash");
  _.object = _.zipObject;
  grunt.initConfig({
    "bower": {
      "dev": {
        "dest": "dist/vendor/js",
        "css_dest": "dist/vendor/css",
        "fonts_dest": "dist/fonts"
      }
    }
  });

  grunt.loadNpmTasks("grunt-bower");

  grunt.registerTask("default", ["bower"]);
};

和我的package.json

{
  "name": "coc-app",
  "version": "1.0.0",
  "description": "Clash of Clans Application",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "private",
  "dependencies": {
    "body-parser": "^1.15.0",
    "cookie-parser": "^1.4.1",
    "express": "^4.13.4",
    "jade": "^1.11.0",
    "lodash": ">=3.0.0 <4.0.0"
  },
  "devDependencies": {
    "grunt": "^1.0.1",
    "grunt-bower": "^0.21.0",
    "grunt-contrib-concat": "^1.0.1"
  }
}

我尝试重置

var _ = require("lodash");

_.object = _.zipObject;

但这不起作用。

有任何想法或建议吗？

Answer 1

问题来自于Underscore和lodash并没有像有些人认为的那样发挥得很好。下划线有_.object，lodash有_.zipObject。

grunt.util和grunt.utils的创建者也不共享相同的库首选项，如grunt.utils._ is a reference to Underscore和grunt.util._ is a reference to lodash和{{3} }，这是您的构建使用的（根据堆栈跟踪）。

这是grunt-bower中的一个错误，假设有_.object时他们显然也在尝试支持grunt.util._并且没有grunt.utils或Underscore作为依赖项。反正...

解决方案

1。包括grunt.utlis

我对Grunt没有太多经验，更不用说grunt.utlis了，但是我怀疑如果你抓住so is grunt-legacy-util._包并按照他们的指导加载它，grunt-bower应该默认为那个（和即，Underscore）。至少看看来源似乎是这样。

2。直接添加_.object方法

我根本不确定这是否会起作用，无论如何它似乎超级hacky，但就像你试图做的那样，

grunt.util._.object = _.zipObject

可能只是没有项目的其他依赖项。我建议你试试第一个。

3。修复grunt-bower *

中的错误

打开一个问题，也许创建公关。它应该只是一个小的变化grunt-utils，所以即使分配回购似乎是一个可靠的选择，如果其他两个不起作用。

更新

to one file。显然它是昨天制作的，所以我打赌它会很快得到合并。评论部分的一点鼓励可能不会有害。

*更新2

修复现在位于主分支中，可通过 v0.21.1

中的npm获取

Answer 2

我暂时没有使用Grunt，但我想我还是会解决这个问题。希望这会有所帮助。

调查

我查看了helper.js文件中的错误，我找到了this line：

var _ = grunt.utils ? grunt.utils._ : grunt.util._;

然后我查看了Grunt docs for Grunt.util，看到Grunt.util._已被弃用。

然后我找到了这个回购：

https://github.com/gruntjs/grunt-legacy-util

我看到了这个通知：

随着Grunt的下一个主要版本，我们将不再支持这些API。如果可能，请使用推荐的模块。如果您想支持或改进任何这些API，请在发布向后兼容的npm模块时通知我们 - 我们将在此处推荐其使用。

所以看起来存在兼容性问题：grunt-bower期望grunt.util._存在，但它不存在于最新版本的Grunt中。

解决方案

您可以使用grunt-legacy-util或只是投入grunt.util._ = require('lodash')来电。这应该可以解决问题。

此外，有人应该让grunt-bower的维护者知道他的库不再与当前版本的Grunt兼容。

修改：我刚刚调查了Grunt的新版本如何填充grunt.util，我看到了this：

var util = require('grunt-legacy-util');
grunt.util = util;

所以现在我感到困惑...... Grunt的新版本仍在提供遗留的工具吗？如果这是真的，那么我不确定为什么你的构建被破坏了。好吧，无论哪种方式，希望这些信息能指出正确的方向。

Answer 3

我发现将'grunt-bower'版本更改为最新版本（0.21.4）可以解决此错误。

详细地说，例如，在bower.js中的grunt-bower@0.21.4，
'_'被定义为lodash，如下所示：

var _ = require('lodash');
