我在heroku上是一个全新的人,我正在尝试部署一个简单的python脚本,该脚本可打印google的源代码。 这是我的脚本:
import os
from selenium import webdriver
op = webdriver.ChromeOptions()
op.binary_location = os.environ.get("GOOGLE_CHROME_BIN")
op.add_argument("--headless")
op.add_argument("--no-sandbox")
op.add_argument("--disable-dev-sh-usage")
driver = webdriver.Chrome(executable_path=os.environ.get("CHROMEDRIVER_PATH"),chrome_options=op)
driver.get('https://google.com')
print(driver.page_source)
这些是我在heroku上的configvars
CHROMEDRIVER_PATH = /app/.chromedriver/bin/chromedriver
GOOGLE_CHROME_BIN = /app/.apt/usr/bin/google-chrome
而我在heroku上遇到的错误是

答案 0 :(得分:0)
TL; DR 您需要将正确的代码(使用chrome_options=op
重新部署到Heroku。
说明
仔细查看回溯。它提到了这一行:
driver = webdriver.Chrome(os.environ.get("CHROMEDRIVER_PATH"),
op)
与您认为执行的代码行不同:
driver = webdriver.Chrome(executable_path=os.environ.get("CHROMEDRIVER_PATH"),
chrome_options=op)
webdriver.Chrome.__init__
的第二个位置参数确实预期为port
,这完全可以解释错误
return ["--port=%d" % self.port] + self.service_args
TypeError: %d format: a number is required, not Options
抱怨self.port
是Options
对象,而不是int
(%d
期望)。
答案 1 :(得分:0)
chrome_options
现在已弃用,而您必须使用options
,有效的代码块将是:
import os
from selenium import webdriver
op = webdriver.ChromeOptions()
op.binary_location = os.environ.get("GOOGLE_CHROME_BIN")
op.add_argument("--headless")
op.add_argument("--no-sandbox")
op.add_argument("--disable-dev-sh-usage")
driver = webdriver.Chrome(executable_path=os.environ.get("CHROMEDRIVER_PATH"), options=op)
