Question

我当时看着this excellent answer，并复制了MacOS的代码（答案的顶部，为方便起见，也在下面复制）。

import os    # Code from answer linked above
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from selenium import webdriver


# path to the firefox binary inside the Tor package
binary = '/Applications/TorBrowser.app/Contents/MacOS/firefox'
if os.path.exists(binary) is False:
    raise ValueError("The binary path to Tor firefox does not exist.")
firefox_binary = FirefoxBinary(binary)


browser = None
def get_browser(binary=None):
    global browser  
    # only one instance of a browser opens, remove global for multiple instances
    if not browser: 
        browser = webdriver.Firefox(firefox_binary=binary)
    return browser

if __name__ == "__main__":
    browser = get_browser(binary=firefox_binary)
    urls = (
        ('tor browser check', 'https://check.torproject.org/'),
        ('ip checker', 'http://icanhazip.com')
    )
    for url_name, url in urls:
        print "getting", url_name, "at", url
        browser.get(url)

我一直收到以下错误。

Traceback (most recent call last):
  File "torselenium.py", line 22, in <module>
    browser = get_browser(binary=firefox_binary)
  File "torselenium.py", line 18, in get_browser
    browser = webdriver.Firefox(firefox_binary=binary)
  File "/Users/user/Library/Python/2.7/lib/python/site-packages/selenium/webdriver/firefox/webdriver.py", line 164, in __init__
    self.service.start()
  File "/Users/user/Library/Python/2.7/lib/python/site-packages/selenium/webdriver/common/service.py", line 83, in start
    os.path.basename(self.path), self.start_error_message)
selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.

此错误与this question中描述的错误非常相似，此处建议设置firefox_binary路径。但是，我已经做到了这一点，并验证（在下面的验证证明中）该路径上存在一个firefox二进制文件。

$ ls /Applications/TorBrowser.app/Contents/MacOS/firefox
/Applications/TorBrowser.app/Contents/MacOS/firefox

实际上，如果我将二进制路径（第7行）设置为'~/Applications/TorBrowser.app/Contents/MacOS/firefox'，它就会给我ValueError，因此肯定有二进制文件。

我也checked if I have execute permissions（我也这样做了，我尝试将browser从全局变量更改为局部变量，无济于事。

如何解决此错误？

您似乎已经足够亲密。使用selenium3通过Selenium驱动的GeckoDriver启动 Mozilla Firefox 浏览上下文，您必须下载最新的GeckoDriver v0.26.0并将其存储在系统中，在启动 Web浏览器会话时，请提及绝对路径，如下所示：

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

您可以在How to connect to Tor browser using Python

您可以在 WebDriverException上找到一些相关的讨论：'geckodriver'可执行文件必须位于PATH 中，错误在于：
