gulp - 无法使用 gulp 运行 Protractor (ECONNREFUSED 连接 ECONNREFUSED)

Question

我以前可以运行它。但现在我不能了。它是在一个项目中。我的 friend 从 git latst 存储库(这也是我导入的方式)拥有这个项目，可以使用 gulp protractor qa 在网关下运行 Protractor 。但对我来说它给出了错误

vegan@vegan:~/xxx-yyyy/gateway$ gulp protractor qa

我没有触及 Protractor 的任何conf文件。它们是默认的。

位于 json 包中

 },
  "engines": {
    "node": "^4.3"
  },

这是 174 的错误行

  request.on('error', function(e) {
    if (e.code === 'ECONNRESET') {
      setTimeout(function() {
        sendRequest(options, callback, opt_data, opt_proxy);
      }, 15);
    } else {
      var message = e.message;
      if (e.code) {
        message = e.code + ' ' + message;
      }
      callback(new Error(message));
    }
  });

这是在 selenumwebdriver 的 packagejson 中

  "readme": "# selenium-webdriver\n\nSelenium is a browser automation library. Most often used for testing\nweb-applications, Selenium may be used for any task that requires automating\ninteraction with the browser.\n\n## Installation\n\nSelenium supports Node `0.12.x` and `4.x`. Users on Node `0.12.x` must run with\nthe --harmony flag. Selenium may be installed via npm with\n\n    npm install selenium-webdriver\n\nOut of the box, Selenium includes everything you need to work with Firefox. You\nwill need to download additional components to work with the other major\nbrowsers. The drivers for Chrome, IE, PhantomJS, and Opera are all standalone\nexecutables that should be placed on your\n[PATH](http://en.wikipedia.org/wiki/PATH_%28variable%29). The SafariDriver\nbrowser extension should be installed in your browser before using Selenium; we\nrecommend disabling the extension when using the browser without Selenium or\ninstalling the extension in a profile only used for testing.\n\n| Browser           | Component                          |\n| ----------------- | ---------------------------------- |\n| Chrome            | [chromedriver(.exe)][chrome]       |\n| Internet Explorer | [IEDriverServer.exe][release]      |\n| PhantomJS         | [phantomjs(.exe)][phantomjs]       |\n| Opera             | [operadriver(.exe)][opera]         |\n| Safari            | [SafariDriver.safariextz][release] |\n\n## Usage\n\nThe sample below and others are included in the `example` directory. You may\nalso find the tests for selenium-webdriver informative.\n\n    var webdriver = require('selenium-webdriver'),\n        By = require('selenium-webdriver').By,\n        until = require('selenium-webdriver').until;\n\n    var driver = new webdriver.Builder()\n        .forBrowser('firefox')\n        .build();\n\n    driver.get('http://www.google.com/ncr');\n    driver.findElement(By.name('q')).sendKeys('webdriver');\n    driver.findElement(By.name('btnG')).click();\n    driver.wait(until.titleIs('webdriver - Google Search'), 1000);\n    driver.quit();\n\n### Using the Builder API\n\nThe `Builder` class is your one-stop shop for configuring new WebDriver\ninstances. Rather than clutter your code with branches for the various browsers,\nthe builder lets you set all options in one flow. When you call\n`Builder#build()`, all options irrelevant to the selected browser are dropped:\n\n    var webdriver = require('selenium-webdriver'),\n        chrome = require('selenium-webdriver/chrome'),\n        firefox = require('selenium-webdriver/firefox');\n\n    var driver = new webdriver.Builder()\n        .forBrowser('firefox')\n        .setChromeOptions(/* ... */)\n        .setFirefoxOptions(/* ... */)\n        .build();\n\nWhy would you want to configure options irrelevant to the target browser? The\n`Builder`'s API defines your _default_ configuration. You can change the target\nbrowser at runtime through the `SELENIUM_BROWSER` environment variable. For\nexample, the `example/google_search.js` script is configured to run against\nFirefox. You can run the example against other browsers just by changing the\nruntime environment\n\n    # cd node_modules/selenium-webdriver\n    node example/google_search\n    SELENIUM_BROWSER=chrome node example/google_search\n    SELENIUM_BROWSER=safari node example/google_search\n\n### The Standalone Selenium Server\n\nThe standalone Selenium Server acts as a proxy between your script and the\nbrowser-specific drivers. The server may be used when running locally, but it's\nnot recommend as it introduces an extra hop for each request and will slow\nthings down. The server is required, however, to use a browser on a remote host\n(most browser drivers, like the IEDriverServer, do not accept remote\nconnections).\n\nTo use the Selenium Server, you will need to install the\n[JDK](http://www.oracle.com/technetwork/java/javase/downloads/index.html) and\ndownload the latest server from [Selenium][release]. Once downloaded, run the\nserver with\n\n    java -jar selenium-server-standalone-2.45.0.jar\n\nYou may configure your tests to run against a remote server through the Builder\nAPI:\n\n    var driver = new webdriver.Builder()\n        .forBrowser('firefox')\n        .usingServer('http://localhost:4444/wd/hub')\n        .build();\n\nOr change the Builder's configuration at runtime with the `SELENIUM_REMOTE_URL`\nenvironment variable:\n\n    SELENIUM_REMOTE_URL=\"http://localhost:4444/wd/hub\" node script.js\n\nYou can experiment with these options using the `example/google_search.js`\nscript provided with `selenium-webdriver`.\n\n## Documentation\n\nAPI documentation is included in the `docs` directory and is also available\nonline from the [Selenium project][api]. Addition resources include\n\n- the #selenium channel on freenode IRC\n- the [<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="b1c2d4ddd4dfd8c4dc9cc4c2d4c3c2f1d6deded6ddd4d6c3dec4c1c29fd2dedc" rel="noreferrer noopener nofollow">[email protected]</a>][users] list\n- [SeleniumHQ](http://www.seleniumhq.org/docs/) documentation\n\n## Contributing\n\nContributions are accepted either through [GitHub][gh] pull requests or patches\nvia the [Selenium issue tracker][issues]. You must sign our\n[Contributor License Agreement][cla] before your changes will be accepted.\n\n## Issues\n\nPlease report any issues using the [Selenium issue tracker][issues]. When using\nthe issue tracker\n\n- __Do__ include a detailed description of the problem.\n- __Do__ include a link to a [gist](http://gist.github.com/) with any\n    interesting stack traces/logs (you may also attach these directly to the bug\n    report).\n- __Do__ include a [reduced test case][reduction]. Reporting \"unable to find\n    element on the page\" is _not_ a valid report - there's nothing for us to\n    look into.

All help\n    inquiries should be directed to the [user forum][users] or #selenium IRC\n    channel.\n- __Do not__ post empty \"I see this too\" or \"Any updates?\" comments. These\n    provide no additional information and clutter the log.\n- __Do not__ report regressions on closed bugs as they are not actively\n    monitored for upates (especially bugs that are >6 months old).

这些是版本

vegan@vegan:~/xx-yyyy/gateway$ node -v
v5.12.0
vegan@vegan:~/xx-yyyy/gateway$ npm -v
3.8.6

我的 friend 也有这个版本，但他可以运行，我也可以，直到上周。我不知道发生了什么事。我删除了节点模块，重置了所有但没有用。

我不知道我可以提供什么信息。

我也尝试过这个

https://stackoverflow.com/a/34758398/6804200

将 configjson 更改为此

{
  "webdriverVersions": {
      "seleniumServerJar": './node_modules/protractor/selenium/selenium-server-standalone-2.51.0.jar',
      "chromedriver": "2.21",
    "iedriver": "2.51.0"
  }
}

但什么都没有改变。

我也做了npm更新

gulp Protractor 是

gulp.task(
    'protractor', function () {


        configObj['args'] = [];//to be able to add multiple parameters

        if (argv.suite) {
            configObj['args'].push(
                '--suite',
                argv.suite
            );
        }

        return gulp.src([])
            .pipe(plumber({errorHandler: handleErrors}))
            .pipe(protractor(configObj))
            .on(
                'error', function () {
                        gutil.log('E2E Tests failed');
                        process.exit(1);
                    }
                );
        }
    );
var configObj = {
    configFile: config.test + 'protractor.conf.js'
};

Protractor 配置是

var HtmlScreenshotReporter = require("protractor-jasmine2-screenshot-reporter");
var JasmineReporters = require('jasmine-reporters');

var prefix = 'src/test/javascript/'.replace(/[^/]+/g, '..');



exports.config = {

    },

    capabilities: {
        'browserName': 'chrome'
    },

    directConnect: true,

    framework: 'jasmine2',

    jasmineNodeOpts: {
        showColors: true,
        defaultTimeoutInterval: 240000
    },
    onPrepare: function () {

        var disableNgAnimate = function () {
            angular
                .module('disableNgAnimate', [])
                .run(
                    [
                        '$animate',
                        function ($animate) {
                            $animate.enabled(false);
                        }
                    ]
                );
        };

        var disableCssAnimate = function () {
            angular
                .module('disableCssAnimate', [])
                .run(
                    function () {
                        var style = document.createElement('style');
                        style.type = 'text/css';
                        style.innerHTML = 'body * {' +
                            '-webkit-transition: none !important;' +
                            '-moz-transition: none !important;' +
                            '-o-transition: none !important;' +
                            '-ms-transition: none !important;' +
                            'transition: none !important;' +
                            '}';
                        document.getElementsByTagName('head')[0].appendChild(style);
                    }
                );
        };

        browser.addMockModule('disableNgAnimate', disableNgAnimate);
        browser.addMockModule('disableCssAnimate', disableCssAnimate);

        browser.driver.manage().window().maximize();


    }
};

gulp 的 qa 任务

gulp.task('qa', function () {

    argv.baseUrl = qaurl;

    configObj['args'].push(
        '--baseUrl',
        argv.baseUrl
    );
});

我在 npm install 时得到了这个

这是一个 Spring Boot 项目。它使用gulp。该项目不需要启动即可运行 Protractor 。

Answer 1

删除并重新安装 npm、gulp、nodejs。
