小编Hea*_*Qiu的帖子

我已经阅读了之前有关此主题的问题并试图遵循建议,但我仍然会遇到错误.在终端上,我跑了

export PATH=$PATH:/Users/Conger/Documents/geckodriver-0.8.0-OSX

我也试过了

    export PATH=$PATH:/Users/Conger/Documents/geckodriver

当我运行以下Python代码时

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities


firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True
firefox_capabilities['binary'] = '/Users/Conger/Documents/Firefox.app'

driver = webdriver.Firefox(capabilities=firefox_capabilities)

我仍然收到以下错误

Python - testwebscrap.py:8
Traceback (most recent call last):

我有一个使用splash的scrapy蜘蛛，该splash运行在Docker localhost：8050上以在渲染之前呈现JavaScript。我正在尝试在heroku上运行此程序，但不知道如何配置heroku以在运行我的Web之前启动docker运行闪屏：scrapy crawl abc dyno。非常感谢任何指导！
