在我的Linux系統,我使用的是Firefox,執行我的計劃,這是我去過的錯誤是:如何解決WebDriverException:在我們可以連接之前,瀏覽器似乎退出了?

Traceback (most recent call last): 

File "shenma_diff_main_v2.py", line 90, in <module> 
    browser = webdriver.Firefox(profile) 
    File "/usr/local/lib/python2.7/site-packages/selenium/webdriver/firefox/webdriver.py", line 59, in __init__ 
    self.binary, timeout), 
    File "/usr/local/lib/python2.7/site-packages/selenium/webdriver/firefox/extension_connection.py", line 47, in __init__ 
    self.binary.launch_browser(self.profile) 
    File "/usr/local/lib/python2.7/site-packages/selenium/webdriver/firefox/firefox_binary.py", line 66, in launch_browser 
    self._wait_until_connectable() 
    File "/usr/local/lib/python2.7/site-packages/selenium/webdriver/firefox/firefox_binary.py", line 100, in _wait_until_connectable 
    raise WebDriverException("The browser appears to have exited " 
selenium.common.exceptions.WebDriverException: Message: The browser appears to have exited before we could connect. If you specified a log_file in the FirefoxBinary constructor, check it for details. 

如果我用root執行我的計劃是確定。

這是因爲您沒有正確設置以在沒有GUI的情況下運行Firefox。 這是一個可能會有所幫助的教程 Selenium Headless Automated Testing in Ubuntu

我想原因是你需要一個終端上指定的端口號,可能xvfb的運行不同的端口比Firefox 上:在另一個
xvfb :99 -ac
終端:
export DISPLAY=:99
和運行scrapy程序 我成功了,而無需使用根
