我遇到了与 FireFox 二进制文件相关的硒错误。

我使用反斜杠将 C:/Users/Mack/AppData/Local/Programs/Python/ 添加到 PATH 并重新启动。我在这里下载了我认为正确的文件https://github.com/mozilla/geckodriver/releases 我将该文件放在连接到 PATH 的目录中。

为了解决这个问题：我尝试使用两个反斜杠

binary = FirefoxBinary("C:\\Users\Mack\AppData\Local\Programs\Python\Python38-32\geckodriver-v0.27.0-win64\geckodriver.exe")

这会引发相同的错误

我尝试使用一个反斜杠

binary = FirefoxBinary("C:\Users\Mack\AppData\Local\Programs\Python\Python38-32\geckodriver-v0.27.0-win64\geckodriver.exe")

这会抛出：

SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape
Traceback (most recent call last):
  File "C:\Users\Mack\Desktop\hacker-stories\Trends.py", line 32, in <module>

from selenium import webdriver;
browser= webdriver.Firefox();
browser.get('http://www.seleniumhq.org');

当我尝试运行此代码时，它给了我一个error 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.

任何想法 - 高度赞赏！

我经常更新Firefox和Chrome浏览器,当前版本54.0.1 32位所以要使用哪个版本的Geckodriver.我试过两个版本Geckodriver-v0.18.0 and geckodriver-v0.16.1

为了将来参考,我在哪里可以找到支持的firefox浏览器列表以及各自的geckodriver版本

注意:启动浏览器中没有任何代码更改

以前的代码是使用geckodriver-v0.16.1为较旧的firefox版本现在在更新firefox 54.0.1和Geckodriver-v0.18.0后获得异常:
