WebDriverException：'geckodriver'可执行文件需要在PATH中，即使它是

Question

尝试让firefox在spyder中使用selenium运行。我目前的代码是

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。

我也尝试将路径导出到〜。/ bash_profile，现在看起来像这样。

# 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

其中gekodriver在

/usr/local/bin

我到处寻找，大多数人都说它应该自动运行，如果它在/ usr / local / bin中，但即使我明确说明路径，它似乎仍然无法找到它。

这是一个运行High Sierra的mac，如果这很重要的话。

Answer 1

此错误消息......

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

...暗示 GeckoDriver 未在预期的默认位置找到。

解决方案

当您使用基于MAC的系统时，您需要传递密钥 executable_path 以及值引用到 GeckoDriver 的绝对路径，如下所示：

from selenium import webdriver

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

其他考虑因素

确保以下内容：

• GeckoDriver存在于指定位置。
• GeckoDriver拥有非root用户的可执行权限。
• 以非root用户身份执行@Test。
