gruntjs - phantomjs无法启动

Question

我在我的项目和karma中使用了AngularJS来测试。然后我这样配置 karma :

config.set({
    basePath: '../',
    frameworks: ['jasmine'],
    files: [
        // bower:js
        'bower_components/jquery/dist/jquery.js',
        'bower_components/angular/angular.js',
        'bower_components/bootstrap/dist/js/bootstrap.js',
        'bower_components/angular-animate/angular-animate.js',
        'bower_components/angular-cookies/angular-cookies.js',
        'bower_components/angular-route/angular-route.js',
        'bower_components/angular-sanitize/angular-sanitize.js',
        'bower_components/angular-mocks/angular-mocks.js',
        // endbower
        'js/**/*.js',
        'test/spec/**/*.js'
    ],
    browsers: [
        'PhantomJS'
    ],
    plugins: [
        'karma-phantomjs-launcher',
        'karma-jasmine'
    ],
    port: 8890

})

像这样 Grunt :

grunt.initConfig({
    connect: {
        testserver: {
            options: {
                base: 'js/',
                hostname: 'localhost',
                port: '8889'
            }
        }
    },
    karma: {
        unit: {
            configFile: './test/karma-unit.conf.js',
            singleRun: true
        }
    } 
});

grunt.registerTask('test', ['connect', 'karma:unit']);

当我输入“grunt test”时，控制台显示 phantomjs 无法启动:

Running "connect:testserver" (connect) task
Started connect web server on http://localhost:8889

Running "karma:unit" (karma) task
INFO [karma]: Karma v0.12.31 server started at http://localhost:8890/
INFO [launcher]: Starting browser PhantomJS
ERROR [launcher]: Cannot start PhantomJS

INFO [launcher]: Trying to start PhantomJS again (1/2).
ERROR [launcher]: Cannot start PhantomJS

INFO [launcher]: Trying to start PhantomJS again (2/2).
ERROR [launcher]: Cannot start PhantomJS

ERROR [launcher]: PhantomJS failed 2 times (cannot start). Giving up.
Warning: Task "karma:unit" failed. Use --force to continue.

Aborted due to warnings.

我该如何解决这个问题？有人可以帮助我吗？

我也遇到了这个问题，似乎是 karma-phantomjs2-launcher 在哪里查找 phantomjs 可执行文件的问题。它使用 PHANTOMJS_BIN 来运行 phantomjs，所以我这样解决了它:

export PHANTOMJS_BIN=/usr/local/bin/phantomjs

只要您也可以从命令行运行“phantomjs”并且它可以工作，那么应该可以做到。
