我怎么能在gruntfile.js中提到phantomjs路径？

Question

Grunt

不支持JSON格式化密钥'phantomjs.binary.path'

grunt.initConfig ({
protractor: {
  options: {
    configFile: './protractor-conf.js',
    keepAlive: true,
    noColor: false
  },

  phantomjs: {
    options: {
        args: {
          capabilities: {

            browserName: "phantomjs",
            'phantomjs.binary.path': './node_modules/.bin/phantomjs',
          },
        },
    }
  },

},
