SessionNotCreatedException：预期的浏览器二进制位置，但无法在从挂载位置访问 GeckoDriver 的默认位置找到二进制文件

Question

我正在尝试在 Google Colab 中使用 Selenium，但在尝试运行 Firefox 实例时出现了一些错误。我关注了这个链接：

• Selenium Documentation 在这里，我尝试使用驱动程序管理软件，但出现错误，提示无法找到 Firefox 的二进制位置。所以我尝试了Hard Coded Location方法，但还是出现同样的错误，所以我认为我必须在google colab中安装firefox，但我不知道这是否是正确的方法

这是我的代码：

from bs4 import BeautifulSoup
from selenium import webdriver
from selenium.webdriver.firefox.service import Service as FirefoxService
from webdriver_manager.firefox import GeckoDriverManager
from google.colab import drive

drive.mount('/content/drive', force_remount=True)

service = FirefoxService(executable_path= '/content/drive/MyDrive/geckodriver')
driver = webdriver.Firefox(service=service)

这是整个错误：

SessionNotCreatedException                Traceback (most recent call last)

<ipython-input-7-51ea1584f592> in <module>()
      1 service = FirefoxService(executable_path= '/content/drive/MyDrive/geckodriver')
----> 2 driver = webdriver.Firefox(service=service)

编辑

我尝试在 Google colab 上安装 firefox，我认为一切都是正确的，但是当它尝试运行 firefox 时，我在 geckodriver.log 上得到了这个输出：

1643070515477   geckodriver INFO    Listening on 127.0.0.1:43355
1643070515979   mozrunner::runner   INFO    Running command: "/usr/bin/firefox" "--marionette" "--headless" "--no-sandbox" "--disable-dev-shm-usage" "--remote-debugging-port" "43945" "-no-remote" "-profile" "/tmp/rust_mozprofileeDGKcf"
src/tcmalloc.cc:283] Attempt to free invalid pointer 0x7fe67e416250 
Redirecting call to abort() to mozalloc_abort

代码如下：

from bs4 import BeautifulSoup
from selenium import webdriver
from selenium.webdriver.firefox.service import Service as FirefoxService
from webdriver_manager.firefox import GeckoDriverManager
from google.colab import drive

drive.mount('/content/drive', force_remount=True)
service = FirefoxService(executable_path= '/content/drive/MyDrive/geckodriver')
options = webdriver.FirefoxOptions()
options.add_argument('--headless')
options.add_argument('--no-sandbox')
options.add_argument('--disable-dev-shm-usage')
driver = webdriver.Firefox(service= service, options= options)

您似乎正在下载 GeckoDriver 并将其存储在 network 位置，然后安装它：

drive.mount('/content/drive', force_remount=True)

根据多次讨论，GeckoDriver / FirefoxService 无法从网络位置启动。

您可以在以下位置找到一些相关讨论：

• CreatePlatformSocket() returned an error: An invalid argument was supplied. (0x2726) when trying to access chromedriver through network path
• CreatePlatformSocket() failed: Address family not supported by protocol and cannot find chrome binary using WebDriverManager in AWS Lambda

解决方案

因此，一个通用的解决方案是通过将 GeckoDriver / Firefox 放入主机的本地驱动器来访问它们。
