phantomjs无法启动

Question

我在我的项目中使用了AngularJS，并使用karma进行了测试。然后我像这样配置了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

})

然后像这样嘟嘟声：

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呢？有人能帮我吗？

Answer 1

我也遇到了这个问题，似乎是karma-phantomjs2-launcher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

只要你也能从命令行运行"phantomjs“并且它能工作，就应该能做到这一点。

Answer 2

安装libfontconfig。假设你使用的是ubuntu：

sudo apt-get install libfontconfig

这为我解决了问题。

Answer 3

在package.json中将karma-phantomjs-launcher版本升级到1.0.2并重新安装包。
