WebDriverException：即使'geckodriver'可执行文件也必须位于PATH中

Question

试图让Firefox在spyder中使用硒运行。我当前的代码是

from selenium import webdriver
import os
os.environ["PATH"] += ":/usr/local/bin/geckodriver"
browser = webdriver.Firefox()

我仍然收到此错误：

runfile('/Users/mherl/Dropbox/AnacondaProjects/MWS/MWSSpyder/test.py', 
wdir='/Users/mherl/Dropbox/AnacondaProjects/MWS/MWSSpyder')
Traceback (most recent call last):

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

即使gekodriver在该文件夹中。

证明gekodriver位置正确

我也尝试过将路径导出到〜。/ bash_profile，现在看起来像这样。

export PATH

export PATH

# added by Anaconda3 5.1.0 installer
export PATH="/Applications/anaconda3/bin:$PATH"

#added by mherl to show path to gekodriver
export PATH=$PATH:/usr/local/bin/gekodriver

我还在spyder中设置了当前路径：

/usr/local/bin
/Users/mherl/Dropbox/AnacondaProjects/MWS/MWSSpyder

gekodriver在其中

/usr/local/bin

我到处都看过，大多数人说如果它位于/ usr / local / bin中，它应该自动运行，但是即使我
明确声明了路径，它仍然似乎找不到。

如果重要的话，这是一台运行High Sierra的Mac。

Answer 1

这个错误讯息…

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

…意味着在预期的默认 位置找不到GeckoDriver
。

解

当您使用基于MAC系统，你需要通过按键executable_path与沿值指的是绝对路径的的GeckoDriver如下：

from selenium import webdriver

browser = webdriver.Firefox(executable_path='/usr/local/bin/geckodriver')

Additional Consideration

Ensure the following :

• GeckoDriver is present in the specified location.
• GeckoDriver is having executable permission for non-root users.
• Execute your @Test as a non-root user.
