量角器给出“无法启动 WebDriver 会话"；错误

Protractor gives quot;Unable to start a WebDriver sessionquot; error(量角器给出“无法启动 WebDriver 会话；错误)

问题描述

我已经使用 webdriver-manager start 启动了一个服务器，但是当我尝试运行量角器时出现此错误:

I already have started a server with webdriver-manager start, but I get this error when I try to run protractor:

Using the selenium server at http://127.0.0.1:4444/wd/hub
[launcher] Running 1 instances of WebDriver
ERROR - Unable to start a WebDriver session.

C:...

ode_modulesprotractor
ode_modulesselenium-webdriverlibatomserror.js:113
  var template = new Error(this.message);
                 ^
UnknownError: unknown error: cannot find Chrome binary

我的配置文件如下所示:

My config file looks like this:

exports.config = {
    specs: [
        'test/*.js'
    ],

    capabilities: {
        'browserName': 'chrome'
    },
    seleniumAddress: 'http://127.0.0.1:4444/wd/hub'

};

我还尝试指向功能对象中的二进制文件以及添加 chromeDriver 和 seleniumServerJar 键均无济于事.有什么想法吗?

I have also tried pointing to the binary in the capabilities object as well as adding chromeDriver and seleniumServerJar keys to no avail. Any ideas?

推荐答案

根据相关github问题，问题是 chromedriver 找不到 chrome 浏览器可执行文件 - 在不同的操作系统上它会在 不同的地方.

According to the relevant github issue, the problem is that chromedriver cannot find chrome browser executeable - on different operating systems it searches for it in different places.

您需要在 chromedriver 期望的地方安装 chrome，或者指定 chrome 在 中可执行的路径>二进制设置:

You need to either have chrome installed where chromedriver expects it to be, or specify the path to the chrome executeable in the binary setting:

capabilities: {
    "browserName": "chrome",
    "chromeOptions": {
        binary: "D:/Program Files/Chrome/chrome.exe",
        args: [],
        extensions: [],
    }
},
