selenium-chromedriver可执行文件需要在路径中

Question

错误消息：

'chromedriver' executable needs to be in PATH

我试图在pycharm中使用selenium编写脚本，但是发生了上述错误。I have already linked my selenium to pycharm as seen here (fresh and up to date)。

我是新来的硒，不是铬河在文件夹“硒” 如果不是，我在哪里可以找到它并添加到路径中？

顺便说一下，我试着在cmd中键入“chromedriver”，但是，它并没有被识别为内部或外部命令。

错误如下所示：

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

Answer 1

试试这个：

pip install webdriver-manager
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager

driver = webdriver.Chrome(ChromeDriverManager().install())

Answer 2

您可以在此处下载ChromeDriver： https://sites.google.com/a/chromium.org/chromedriver/downloads

那么您有多个options：

• 将其添加到系统中path
• 将它放在与python脚本相同的目录中

• 直接通过executable_path指定位置

  driver = webdriver.Chrome(executable_path='C:/path/to/chromedriver.exe')
  

Answer 3

另一种方法是下载并解压chromedriver，并将'chromedriver.exe'放在C:\ Python27\Scripts中，然后不需要提供驱动程序的路径，只需

driver= webdriver.Chrome()

会有用的
