Question

我正在尝试学习Python的Webdriver，使用对Python的基本了解，以及对Selenium和JAVA的更广泛理解。我按照找到的here指南进行了操作。我的代码：

import unittest
from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://www.google.com")
assert "Google" in driver.title
sb = driver.find_element_by_name(lst-ib)
sb.clear()
sb.send_keys("Youtube")
sb.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
driver.close()

现在，在PyCharm中运行它将返回：

C:\Users\mbrenn002c\AppData\Local\Programs\Python\Python35-32\python.exe C:/Users/mbrenn002c/PycharmProjects/PyDriver/Webdriver.py
Traceback (most recent call last):
  File "C:/Users/mbrenn002c/PycharmProjects/PyDriver/Webdriver.py", line 5, in <module>
    driver = webdriver.Firefox()

    keep_alive=True)

    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: 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


Process finished with exit code 1

我的pip包是：selenium; beautifulsoup4。

我的PATH看起来像这样：

%USERPROFILE%\AppData\Local\Mirosoft\WindowsApps;C:\Users\myuser\AppData\Programs\Python;C:\Pythone34;C:\Users\myuser\Desktop\File transfer\Eclipse Items\geckodrver.exe

我的主要问题是;我究竟做错了什么？据我所知，我已经正确地遵循了一切，这段代码应该打开geckodriver并按照列出的方式工作。它甚至不能运行selenium独立服务器来运行webdriver。

我尝试在我的QPython客户端上使用相同的pip和代码运行它来安装我的Android手机，它在控制台中返回了一些回调，最后是这样：

 Exception AttributeError: "'Service' object has no attribute 'log_file'" in <bound method Service.__del__ of <seleniumwebdriver.firefox.service.Service object at 0xf5e709f0>> ignored

可能值得注意的是，我的手机还没有Root，我真正做的就是保存这个脚本，然后点击安装Selenium和beautifulsoup4。

Answer 1

selenium.common.exceptions.WebDriverException：消息：预期浏览器二进制位置，但默认情况下无法找到二进制文件 location，没有提供'moz：firefoxOptions.binary'功能，没有在命令行上设置二进制标志

异常显然表明Firefox已安装了与Selenium不同的目录。尝试访问默认路径但找不到。您需要描述代码中firefox的安装位置。

使用下面的代码段

import unittest
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

binary = FirefoxBinary('path/to/installed firefox binary')
driver = webdriver.Firefox(firefox_binary=binary)

driver.get("http://www.google.com")
assert "Google" in driver.title
sb = driver.find_element_by_name(lst-ib)
sb.clear()
sb.send_keys("Youtube")
sb.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
driver.close()

即使PATHed正常运行，Python Selenium Webdriver仍然无法运行，并且脚本按照指示编写
