从带有virtualenv的Visual Studio Code终端运行硒

Question

我已经尝试了2个多小时才能从Visual Studio终端运行我的刮板。起初我以为问题是我的chromedriver / geckodriver不是由正确的用户拥有的/没有正确的读写权限，所以我检查了一下。我的virtualenv也归用户所有并具有适当的权利。当我从控制台运行脚本时，它可以工作（这意味着首先激活virtualenv，然后以用户身份运行脚本。因此，这不是chromedriver问题（甚至不是路径问题）。当我尝试从Visual Studio Code终端运行它时，它不起作用，并且我不断得到：

chromedriver的此错误：

    paras = self.driver.find_elements(By.XPATH, "//p")
  File "/home/mike/Documents/Envs/Scrapers/lib/python3.7/site-packages/selenium/webdriver/remote/webdriver.py", line 1007, in find_elements
    'value': value})['value'] or []
  File "/home/mike/Documents/Envs/Scrapers/lib/python3.7/site-packages/selenium/webdriver/remote/webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "/home/mike/Documents/Envs/Scrapers/lib/python3.7/site-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: chrome not reachable
  (Session info: chrome=77.0.3865.120)

以及firefox的此错误：

    return webdriver.Firefox()
  File "/home/mike/Documents/Envs/Scrapers/lib/python3.7/site-packages/selenium/webdriver/firefox/webdriver.py", line 174, in __init__
    keep_alive=True)
  File "/home/mike/Documents/Envs/Scrapers/lib/python3.7/site-packages/selenium/webdriver/remote/webdriver.py", line 157, in __init__
    self.start_session(capabilities, browser_profile)
  File "/home/mike/Documents/Envs/Scrapers/lib/python3.7/site-packages/selenium/webdriver/remote/webdriver.py", line 252, in start_session
    response = self.execute(Command.NEW_SESSION, parameters)
  File "/home/mike/Documents/Envs/Scrapers/lib/python3.7/site-packages/selenium/webdriver/remote/webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "/home/mike/Documents/Envs/Scrapers/lib/python3.7/site-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: invalid argument: can't kill an exited process

我在项目的python文件中提供了settings.json的适当路径，例如：

{
    "python.pythonPath": "/home/mike/Documents/Envs/Scrapers/bin/python3"
}

尝试使其正常运行，如果这样可以解决打开新显示器的问题。

在VS Code终端中粘贴以下内容，然后重试

export DISPLAY=":0"
