"WebDriverException: 'geckodriver' executable needs to be in PATH" 错误，而 'driver = webdriver.Firefox()' 通过 Selenium

Question

对于那里的专家，我运行使用 Spyder（在 Mac 上）在 Python 中编写了以下代码：

>from selenium import webdriver
>from selenium.webdriver.common.keys import Keys
>driver = webdriver.Firefox()

我收到以下错误：

>Traceback (most recent call last):
>
>  File "<ipython-input-4-fd567e24185f>", line 1, in <module>
>    driver = webdriver.Firefox()
>
>  File "/Users/liminfang/anaconda3/lib/python3.6/site->packages/selenium/webdriver/firefox/webdriver.py", line 160, in __init__

>    os.path.basename(self.path), self.start_error_message)
>
>WebDriverException: 'geckodriver' executable needs to be in PATH.

请注意，我已经通过执行

添加了 'geckodriver' 可执行文件到 PATH

>export PATH=$PATH:/Users/liminfang/anaconda3/geckodriver

在终端中。我重新启动了我的电脑，但错误仍然存在。有人知道这里发生了什么吗？请帮忙。谢谢！

Answer 1

将 geckodriver.exe 放入 脚本文件夹 然后调用 webdriver.Firefox ：

driver = webdriver.Firefox(firefox_binary=binary, firefox_profile=fp, executable_path='geckodriver.exe')

我有 52.0.2（64 位）和 Geckodriver 0.15.0-win64，它正在运行！

Answer 2

这个错误信息...

WebDriverException: 'geckodriver' executable needs to be in PATH.

...表示在您在 PATH 变量中提到的目录中找不到 GeckoDriver。

解决方案

当您使用 ipython 时，您可以从 mozilla/geckodriver 下载最新的 GeckoDriver 并将其放置在任何地方在你的系统内。在初始化新的 WebDriver/WebClient 会话时传递 absolute GeckoDriver 的路径二进制通过executable_path参数如下：

from selenium import webdriver
driver = webdriver.Firefox(executable_path='/path/to/geckodriver')

"WebDriverException: 'geckodriver' executable needs to be in PATH" 错误，而 'driver = webdriver.Firefox()' 通过 Selenium

"WebDriverException: 'geckodriver' executable needs to be in PATH" error while 'driver = webdriver.Firefox()' through Selenium

python

firefox

selenium

selenium-webdriver

geckodriver
