Grunt won't load the node server

问题

My gruntfile.js is:

'use strict';

module.exports = function(grunt) {
    // Project Configuration
    grunt.initConfig({
        pkg: grunt.file.readJSON('package.json'),
        watch: {
            jade: {
                files: ['app/views/**'],
                options: {
                    livereload: true,
                },
            },
            js: {
                files: ['gruntfile.js', 'server.js', 'app/**/*.js', 'public/js/**', 'test/**/*.js'],
                tasks: ['jshint'],
                options: {
                    livereload: true,
                },
            },
            html: {
                files: ['public/views/**'],
                options: {
                    livereload: true,
                },
            },
            css: {
                files: ['public/css/**'],
                options: {
                    livereload: true
                }
            }
        },
        jshint: {
            all: {
                src: ['gruntfile.js', 'server.js', 'app/**/*.js', 'public/js/**', 'test/**/*.js'],
                options: {
                    jshintrc: true
                }
            }
        },
        nodemon: {
            dev: {
                options: {
                    file: 'server.js',
                    args: [],
                    ignoredFiles: ['public/**'],
                    watchedExtensions: ['js'],
                    nodeArgs: ['--debug'],
                    delayTime: 1,
                    env: {
                        PORT: 3000
                    },
                    cwd: __dirname
                }
            }
        },
        concurrent: {
            tasks: ['nodemon', 'watch'],
            options: {
                logConcurrentOutput: true
            }
        },
        mochaTest: {
            options: {
                reporter: 'spec',
                require: 'server.js'
            },
            src: ['test/mocha/**/*.js']
        },
        env: {
            test: {
                NODE_ENV: 'test'
            }
        },
        karma: {
            unit: {
                configFile: 'test/karma/karma.conf.js'
            }
        }
    });

    //Load NPM tasks 
    grunt.loadNpmTasks('grunt-contrib-watch');
    grunt.loadNpmTasks('grunt-contrib-jshint');
    grunt.loadNpmTasks('grunt-mocha-test');
    grunt.loadNpmTasks('grunt-karma');
    grunt.loadNpmTasks('grunt-nodemon');
    grunt.loadNpmTasks('grunt-concurrent');
    grunt.loadNpmTasks('grunt-env');

    //Making grunt default to force in order not to break the project.
    grunt.option('force', true);

    //Default task(s).
    grunt.registerTask('default', ['jshint', 'concurrent']);

    //Test task.
    grunt.registerTask('test', ['env:test', 'mochaTest', 'karma:unit']);
};

and when I type grunt, I get:

$ grunt
Running "jshint:all" (jshint) task
>> 69 files lint free.

Running "concurrent:tasks" (concurrent) task
Running "nodemon:dev" (nodemon) task
Running "watch" task
Waiting...

Usually it says Express started on Port 3000, but suddenly it isn't. Not sure what's going on. Any ideas?

When running with the -v flag, I get:

Running tasks: nodemon

    Running "nodemon" task

    Running "nodemon:dev" (nodemon) task
    Verifying property nodemon.dev exists in config...OK

Look at the changelog of grunt-nodemon: https://github.com/ChrisWren/grunt-nodemon#changelog.

You must have update your dependencies recently and grunt-nodemon changed a few properties.

- file is now script
- ignoredFiles -> ignore
- watchedFolders -> watch
- watchedExtensions -> ext

回答2:

Just change you options.file to script or keep both.

nodemon: {
    dev: {
        script: 'server.js',
        options: {
            file: 'server.js',
            args: [],
            ignoredFiles: ['public/**'],
            watchedExtensions: ['js'],
            nodeArgs: ['--debug'],
            delayTime: 1,
            env: {
                PORT: 3000
            },
            cwd: __dirname
        }
    }
}
