我之前在 Java 和 OpenSUSE 中使用过 Selenium 2。现在,我在 Mac 上并希望将其设置为与 Python 2.7 一起使用。我已经下载并解压缩了 selenium 2.28 并下载了 ChromeDriver 并将其保存在 /Users/username/Downloads 中。并更新 bash_profile 中的路径。但是,当我像这样运行一个简单的代码片段时,
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Chrome()
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.send_keys("selenium")
elem.send_keys(Keys.RETURN)
assert "Google" in driver.title
driver.close()
我只是从文档中拿来测试。我收到如下错误:
Traceback (most recent call last):
File "python_selenium_testing.py", line 4, in <module>
driver = webdriver.Chrome()

selenium.common.exceptions.WebDriverException: Message: 'ChromeDriver executable needs to be available in the path. Please download from http://code.google.com/p/selenium/downloads/list and read up at http://code.google.com/p/selenium/wiki/ChromeDriver'
但是,chromedriver 正在路上。这就是 echo $PATH 给我的:
Other stuff:***/Users/rohitdholakia/Downloads/chromedriver***
可能缺少什么?
