Question

我有一个使用Python3.6运行时的aws lambda函数，带有firefox69，geckodriver25和selenium3.14的3个lambda层，我不确定从哪个方向使firefox在lambda上运行。

这是我的代码：

#from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
from selenium import webdriver
from selenium.webdriver.firefox.options import Options
path = '/tmp/'

# FIREFOX
def start_browser(url, headless=True):
    try:
        fp = webdriver.FirefoxProfile()
        options = Options()
        if headless==True:
            options.headless = True
        #caps = DesiredCapabilities.FIREFOX.copy()
        #caps['marionette'] = False
        fp.set_preference("browser.preferences.instantApply",True)
        fp.set_preference("browser.helperApps.neverAsk.saveToDisk", "text/xls, application/vnd.ms-excel")
        fp.set_preference("browser.helperApps.alwaysAsk.force",False)
        fp.set_preference("browser.download.dir", path)
        fp.set_preference("browser.download.folderList", 2)
        fp.set_preference("browser.download.manager.showWhenStarting", False)
        browser = webdriver.Firefox(
            options=options,
            #capabilities=caps,
            executable_path="/opt/python/geckodriver",
            log_path="/tmp/geckodriver.log",
            firefox_profile=fp,
            firefox_binary="/opt/python/firefox/firefox"
        )
        browser.get(url)
        return browser
    except Exception as e:
        print(e)
    finally:
        f = open('/tmp/geckodriver.log', 'r')
        file_contents = f.read()
        print("LOG FILE CONTENT: " + file_contents + "END")
        f.close()

在lambda中运行以上命令会给我错误

Message: invalid argument: can't kill an exited process

但是，如果我取消注释“大写”行，则会出现此错误

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.

但是我的geckodriver.log是空的
