Javascript GruntJS可以在复制文件后删除bower_components文件夹吗？

我正在使用Bower和GruntJS。我原以为grunt bowercopy在完成后会删除

bower\u components

文件夹，但事实并非如此

grunt bowercopy能否在将文件复制到所需位置后删除bower_components文件夹

以下是我的文件夹设置：

->Project
    ->Themes
        ->Theme
            ->assets
                ->scripts
                ->styles
    ->tools
        ->build
            ->bower_components
            ->bower.json
            ->gruntfile.js
            ->package.json

下面是我如何在gruntfile.js中运行grunt bowercopy

module.exports = function (grunt) {

// Loads the necessary tasks for this Grunt file.
    require('matchdep').filterDev('grunt-*').forEach(grunt.loadNpmTasks);

    // Project configuration.
    grunt.initConfig({

        pkg: grunt.file.readJSON('package.json'),

        bowercopy: {
          options: {
            clear: true
          },
          js: {
            options: {
                destPrefix: '../../Themes/Theme/assets/'
            },
            //The key is the destination file.  The value is the file from the bower_components folder
            //The files will be added to a scripts folder at the location: ../../themes/3MTheme/assets/scripts
            //The key is the name of the folder that is copied into the /assets folder.
            src : 'scripts'

          },
          css: {
            options: {
                destPrefix: '../../Themes/Theme/assets/'
            },
            src: 'styles'

          }
       }

      // Custom task, executed via the command "grunt bowercopy"
      grunt.registerTask('bower', ['bowercopy']);
};    

module.exports = function (grunt) {

// Loads the necessary tasks for this Grunt file.
require('matchdep').filterDev('grunt-*').forEach(grunt.loadNpmTasks);

// Project configuration.
grunt.initConfig({

    pkg: grunt.file.readJSON('package.json'),

    bowercopy: {
      options: {
        clean: true
      },
      js: {
        options: {
            destPrefix: '../../Themes/Theme/assets/'
        },
        //The key is the destination file.  The value is the file from the bower_components folder
        //The files will be added to a scripts folder at the location: ../../themes/3MTheme/assets/scripts
        //The key is the name of the folder that is copied into the /assets folder.
        src : 'scripts'

      },
      css: {
        options: {
            destPrefix: '../../Themes/Theme/assets/'
        },
        src: 'styles'

      }
   }

  // Custom task, executed via the command "grunt bowercopy"
  grunt.registerTask('bower', ['bowercopy']);
};

我找到了答案。我在选项中使用了

clear:true

，而它应该是

clean:true

这在我的gruntfile.js中起作用

module.exports = function (grunt) {

// Loads the necessary tasks for this Grunt file.
    require('matchdep').filterDev('grunt-*').forEach(grunt.loadNpmTasks);

    // Project configuration.
    grunt.initConfig({

        pkg: grunt.file.readJSON('package.json'),

        bowercopy: {
          options: {
            clear: true
          },
          js: {
            options: {
                destPrefix: '../../Themes/Theme/assets/'
            },
            //The key is the destination file.  The value is the file from the bower_components folder
            //The files will be added to a scripts folder at the location: ../../themes/3MTheme/assets/scripts
            //The key is the name of the folder that is copied into the /assets folder.
            src : 'scripts'

          },
          css: {
            options: {
                destPrefix: '../../Themes/Theme/assets/'
            },
            src: 'styles'

          }
       }

      // Custom task, executed via the command "grunt bowercopy"
      grunt.registerTask('bower', ['bowercopy']);
};    

module.exports = function (grunt) {

// Loads the necessary tasks for this Grunt file.
require('matchdep').filterDev('grunt-*').forEach(grunt.loadNpmTasks);

// Project configuration.
grunt.initConfig({

    pkg: grunt.file.readJSON('package.json'),

    bowercopy: {
      options: {
        clean: true
      },
      js: {
        options: {
            destPrefix: '../../Themes/Theme/assets/'
        },
        //The key is the destination file.  The value is the file from the bower_components folder
        //The files will be added to a scripts folder at the location: ../../themes/3MTheme/assets/scripts
        //The key is the name of the folder that is copied into the /assets folder.
        src : 'scripts'

      },
      css: {
        options: {
            destPrefix: '../../Themes/Theme/assets/'
        },
        src: 'styles'

      }
   }

  // Custom task, executed via the command "grunt bowercopy"
  grunt.registerTask('bower', ['bowercopy']);
};

看起来grunt bowercopy并没有为您这样做，但我已经做了类似的事情，在运行测试命令之前清除报告

只需创建自己的自定义任务，名为cleanbowercopy，该任务在正在清理的目录上执行

然后更新注册任务以在bowercopy之后调用它：

grunt.registerTask('bower',['bowercopy','cleanbowercopy']);

---

这样，它就可以在同一个命令中完成所需的任务，如果您希望在不同的时间点清理目录，它甚至可以重复使用。

如果它在您构建项目后删除bower_components文件夹，您将需要在下一次构建中再次安装这些组件，对吗？为什么要删除该文件夹？它只用于开发目的，不进入dist文件夹。@Sergey，我正在从共享服务器复制一些文件。这些文件可能会被其他人偶尔更新，我想确保我拉下这些最新的更新。谢谢！这真是个好主意。看起来grunt bowercopy将删除bower_components文件夹，我只是在发布到这里之后才发现我的错误。
