埃尔卡皮坦的无根打破旧的咕噜配置吗？

Question

迁移到El Capitan后，用户似乎遇到了grunt安装问题，可能与El Capitan的无根更改有关。特别是，运行grunt--force命令会导致EPERM错误。工作流程如下：

假设已经安装了npm，请使用包导航到grunt目录。json和GrunFile。js和调用grunt：

grunt --force

例如Grunfile。js文件内容：

module.exports = function(grunt) {

    // All configuration goes here 
    grunt.initConfig({
        pkg: grunt.file.readJSON('package.json'),

        concat: {
            // Configuration for concatenating files goes here.
            dist: {
                src: [
                        '../js/libs/owl.carousel.js',
                        '../js/libs/jquery.actual.js',
                        '../js/libs/chosen.jquery.js',
                        '../js/libs/jquery.parallax.js',
                        '../js/src/common.js'  
                ],
                dest: '../js/pro/global.js',
            },
        },

        uglify: {
            build: {
                src: '../js/pro/global.js',
                dest: '../js/pro/global.min.js',
            },
        },


        imagemin: {
            dynamic: {
                files: [{
                    expand: true,
                    cwd: '../img/src/',
                    src: ['**/*.{png,jpg,gif}'],
                    dest: '../img/pro/'
                }]
            }
        },

        compass: {
            dev: {
                options: {              
                    sassDir: '../sass',
                    cssDir: '../css',
                    fontsDir: '../fonts',
                    imagesDir: '../img/',
                    images: '../img/',
                    javascriptsDir: '../js/pro',
                    //environment: 'development',
                    outputStyle: 'compressed',
                    relativeAssets: true,
                    httpPath: '.',
                }
            },
        },

        watch: {
            scripts: {
                files: ['../js/**/**.js'],
                tasks: ['concat', 'uglify'],
                options: {
                    spawn: true,
                },
            },
            images: {
                files: ['../img/src/**.{png,jpg,gif}'],
                tasks: ['imagemin'],
                options: {
                    spawn: true,
                }
            },
            compass: {
                files: ['../**/*.{scss,sass}'],
                tasks: ['compass:dev'],
            }

        },

        svgstore: {
            defaults: {
                options: {
                    prefix : 'icon-',
                },
                files: {
                    '../img/svg-defs.svg': ['../img/svg/*.svg']
                }
            }
        },


    });

    // Where we tell Grunt we plan to use this plug-in.
    grunt.loadNpmTasks('grunt-contrib-concat');
    grunt.loadNpmTasks('grunt-contrib-uglify');
    grunt.loadNpmTasks('grunt-contrib-imagemin');
    grunt.loadNpmTasks('grunt-contrib-watch');
    grunt.loadNpmTasks('grunt-contrib-compass');
    grunt.loadNpmTasks('grunt-svgstore');

    // Where we tell Grunt what to do when we type "grunt" into the terminal.
    grunt.registerTask('default', ['concat', 'uglify', /*'imagemin',*/ 'compass', 'svgstore', 'watch']);

};

示例包。json文件内容：

{
"name": "Call Me Maybe",
"version": "0.2.0",
"devDependencies": {
    "grunt": "^0.4.5",
    "grunt-contrib-compass": "^1.0.4",
    "grunt-contrib-concat": "^0.5.1",
    "grunt-contrib-imagemin": "^0.9.4",
    "grunt-contrib-sass": "^0.9.2",
    "grunt-contrib-uglify": "^0.9.2",
    "grunt-contrib-watch": "^0.6.1",
    "grunt-svgstore": "^0.5.0"
  }
}

产生的EPERM错误如下所示：

Running "concat:dist" (concat) task
Warning: Unable to write "../js/pro/global.js" file (Error code: EPERM). Used --force, continuing.

Running "uglify:build" (uglify) task
Warning: Unable to write "../js/pro/global.min.js" file (Error code: EPERM). Used --force, continuing.

有趣的是，Ruby和Compass也安装了，所以它确实符合无根无法写入文件夹问题的理论，但是依赖内核如何移动到其他地方（即 /usr/local/bin），所以这不是问题？

在El Capitan Betas期间，一些用户建议通过终端启用root，尽管这似乎不再有效，因为错误仍然存在，/usr/bin文件夹仍然不允许权限更改。

Answer 1

在 /usr/bin上安装非系统软件是一个糟糕的举动，现在在埃尔卡皮坦是被禁止的，这是有充分理由的。

我不熟悉grunt，但是如果您可以使用/usr/local/bin，那么可能一切都正常。

Answer 2

对于遇到相同问题的用户，我必须取消使用路径：/usr/bin中安装的二进制文件，并在更新路径/usr/local/bin后重新安装。鲁比往往是罪魁祸首。因为我很难找到我所有的ruby安装，所以我最终安装了rbenv来管理我的ruby版本。

以下终端命令可能有助于识别有问题的路径：

which ruby
gem environment
gem uninstall [insert gem name here]
[google how to set your paths to /usr/local/bin... (will be in a hidden file)]
gem install [insert gem name here]
