推荐答案
此错误消息...
selenium.common.exceptions.SessionNotCreatedException: Message: Expected browser binary location, but unable to find binary in default location, no 'moz:firefoxOptions.binary' capability provided, and no binary flag set on the command line
...表示 GeckoDriver在尝试启动/产生新的 Browsing Context 即 Firefox Browser 会话时,无法找到 firefox 二进制文件.
...implies that the GeckoDriver was unable to locate the firefox binary while trying to initiate/spawn a new Browsing Context i.e. Firefox Browser session.
此错误的可能原因可能是以下之一:
The probable reason for this error can be either of the following:
- 您的系统中未安装
- Firefox .
- Firefox 未安装在系统的默认位置.
- Firefox isn't installed in your system.
- Firefox isn't installed in the default location within your system.
可能的解决方案是:
-
如果系统中未安装 Firefox ,则需要先安装它,然后再执行测试.
If Firefox isn't installed in your system, you need to install it before executing your tests.
如果将 Firefox 安装在自定义位置,则需要通过以下方式传递 firefox 二进制文件的绝对路径: Options()
实例:
If Firefox is installed at a customized location, you need to pass the absolute path of the firefox binary as follows through an Options()
instance:
from selenium import webdriver
from selenium.webdriver.firefox.options import Options
options = Options()
options.binary_location = r"C:/location/to/Firefox/Binary/firefox.exe"
driver = webdriver.Firefox(options=options, executable_path="C:/location/to/geckodriver.exe")
driver.get('http://google.com/')

- InvalidArgumentException:消息:二进制不是使用GeckoDriver Firefox Selenium和Python的Firefox可执行错误
- 预期浏览器的二进制位置,但无法在默认位置找到二进制,因此未提供"moz:firefoxOptions.binary"功能
- 预期浏览器的二进制位置,但无法在默认位置找到二进制文件,没有使用GeckoDriver提供的'moz:firefoxOptions.binary'功能
