启动Chrome时如何解决“获取默认适配器失败"错误，并尝试通过使用Selenium的ChromeDriver访问网页 [英] How to solve 'Getting Default Adapter failed' error when launching Chrome and try to access a webpage using the ChromeDriver using Selenium

问题描述

我已经更新了Selenium，但是即使加载了网页，该错误仍然会继续发生.但是，在某些情况下，驱动程序会启动，但停滞不前.这是否引起了问题?如果是，该如何解决?

I have updated Selenium but the error keeps occurring even though the web page loads. However, in some instances, the driver starts but it is stagnant. Is this causing an issue and if so, how do I resolve it?

[11556:9032:0502/152954.314:ERROR:device_event_log_impl.cc(162)] [15:29:54.314] Bluetooth: bluetooth_adapter_winrt.cc:1055 Getting Default Adapter failed.

推荐答案

此错误消息...

ERROR:device_event_log_impl.cc(162)] [15:29:54.314] Bluetooth: bluetooth_adapter_winrt.cc:1055 Getting Default Adapter failed.

...表示ScopedClosureRunner on_init在BluetoothAdapterWinrt::OnGetDefaultAdapter()中失败.

...implies that ScopedClosureRunner on_init failed in BluetoothAdapterWinrt::OnGetDefaultAdapter().

此错误在 bluetooth_adapter_winrt.cc 中定义a>如下:

This error is defined in bluetooth_adapter_winrt.cc as follows:

void BluetoothAdapterWinrt::OnGetDefaultAdapter(
    base::ScopedClosureRunner on_init,
    ComPtr<IBluetoothAdapter> adapter) {
  DCHECK_CALLED_ON_VALID_THREAD(thread_checker_);
  if (!adapter) {
    BLUETOOTH_LOG(ERROR) << "Getting Default Adapter failed.";
    return;
  }

Solution

Ensure that:

• 硒已升级到当前级别版本3.141.59 .
• ChromeDriver 已更新为当前的 ChromeDriver v84.0 级别.
• Chrome 已更新为当前的 Chrome版本84.0 级别. (根据 ChromeDriver v84.0发行说明)
• 如果您的基本 Web客户端版本太旧，则将其卸载并安装最新版本的 Web客户端 GA.

• Selenium is upgraded to current levels Version 3.141.59.
• ChromeDriver is updated to current ChromeDriver v84.0 level.
• Chrome is updated to current Chrome Version 84.0 level. (as per ChromeDriver v84.0 release notes)
• If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.

但是据观察，通过在Linux上以 root 用户( administrator )运行Chrome，可以消除此错误.但这可能与 ChromeDriver中的文档有所不同-提到的WebDriver for Chrome :

However it was observed that this error can be supressed by running Chrome as root user (administrator) on Linux. but that would be a deviation from the documentation in ChromeDriver - WebDriver for Chrome where it is mentioned:

Chrome在启动过程中崩溃的常见原因是在Linux上以root用户(管理员)身份运行Chrome.虽然可以通过在创建您的 ChromeDriver 会话，因为这种配置不受支持并且不建议使用.

A common cause for Chrome to crash during startup is running Chrome as root user (administrator) on Linux. While it is possible to work around this issue by passing '--no-sandbox' flag when creating your WebDriver session, i.e. the ChromeDriver session as such a configuration is unsupported and highly discouraged.

理想情况下，您需要配置您的环境以改为以普通用户身份运行Chrome.

Ideally, you need to configure your environment to run Chrome as a regular user instead.

最后，按照

Finally, as per the documentation in Selenium Chrome Driver: Resolve Error Messages Regarding Registry Keys and Experimental Options these error logs can be supressed by adding the argument:

excludeSwitches: ['enable-logging']

因此，您的有效代码块将是:

So your effective code block will be:

from selenium import webdriver

options = webdriver.ChromeOptions() 
options.add_experimental_option("excludeSwitches", ["enable-logging"])
driver = webdriver.Chrome(options=options, executable_path=r'C:\WebDrivers\chromedriver.exe')
driver.get("https://www.google.com/")
