Why protractor on soucelab throw error about bad class invoked?

I has project based on protractor, cucumber... tests was running by selenium on soucelab.

Gulpfile run protractor config by gulp-protractor. Its code of config:

    exports.config = {
    sauceUser: "SOUCELABUSER",
    sauceKey: "SOUCELABKEY",
    allScriptsTimeout: 100000,
    getPageTimeout: 100000,
    specs: [
        'e2e/features/*.feature'
    ],
    cucumberOpts: {
        require: [
            'e2e/step_definitions/**/*.js',
            '../index.js', // include predefined steps
            'e2e/page_objects/index.js'
        ],
        format: ["pretty", "json:cucumberReport.json"]
    },
    multiCapabilities: [
        {
            browserName: 'internet explorer',
            version: '11.103',
            platform: "Windows 10",
            cucumberOpts: {
                format: ["pretty", "json:ieCucumberReport.json"]
            }
        },
        {
            'browserName': 'chrome',
            cucumberOpts: {
                format: ["pretty", "json:chromeCucumberReport.json"]
            }
        },
        {
            'browserName': 'firefox',
            cucumberOpts: {
                format: ["pretty", "json:firefoxCucumberReport.json"]
            }
        }
    ],
    framework: 'custom',
    frameworkPath: require.resolve('protractor-cucumber-framework')
};

On my friend PC (windows) tests start correctly. On my Ububntu 14 its throw this:

(node:6900) fs: re-evaluating native module sources is not supported. If you are using the graceful-fs module, please update it to a more recent version.
