尝试在 spyder 中使用 selenium 运行 Firefox.我当前的代码是

Trying to get firefox to run using selenium in spyder. My current code is

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

我仍然收到此错误:

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

即使 gekodriver 在该文件夹中.

Even though gekodriver is in that folder.

我也尝试将路径导出到 ~./bash_profile 现在看起来像这样.

I have also tried exporting the path to ~./bash_profile which looks like this right now.

export PATH=$PATH:/usr/local/bin/gekodriver

我还在 spyder 中设置了当前路径:

I also have the current paths set in spyder:

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

其中gekodriver在

of which gekodriver is in

/usr/local/bin

我到处寻找，大多数人都说如果它在/usr/local/bin 中应该会自动运行，但即使我明确指出路径，它似乎仍然找不到它.

I have looked everywhere and most people say it should run automatically if it's in /usr/local/bin but it still can't seem to find it even when I explicitly state the path.

如果这很重要，这是运行 High Sierra 的 mac.

This is a mac running High Sierra if that's important.

推荐答案

此错误信息...

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

...表示在预期的默认位置找不到 GeckoDriver.

...implies that the GeckoDriver wasn't found in the expected default location.

当您使用基于MAC 的系统时，您需要传递Key executable_path 和 Value 引用到GeckoDriver的绝对路径如下:

As you are using MAC based System you need to pass the Key executable_path along with the Value referring to the absolute path of the GeckoDriver as follows :

from selenium import webdriver

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

其他注意事项

确保以下几点:

• GeckoDriver 存在于指定位置.
• GeckoDriver 对非 root 用户具有可执行权限.
• 以非 root 用户身份执行 @Test.
