未知错误：Chrome 无法启动：异常退出。 Chrome 无法在 selenium webdriver 中打开

Question

我创建了一个安装了 ububtu 的 EC2 实例。我已经安装了 python3-pip 和 selenium webdriver 以及在其上运行 selenium 的其他要求。

我正在使用这段代码，但它引发了这个错误。

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from webdriver_manager.chrome import ChromeDriverManager
    
chrome_options = Options()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')

driver = webdriver.Chrome(ChromeDriverManager().install())
driver.get("https://hagadmansa.com")
driver.set_window_size(1300, 500)
driver.save_screenshot("a.png")
driver.quit()
print("Done")

我正在使用此代码截取特定网站的屏幕截图，但它引发了此错误。

  (The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

尝试从终端卸载 selenium 包并再次重新安装它也使用 python 版本 3.9 或 3.8 因为 3.10 不是用于开发的稳定版本。
