Heroku未知错误:找不到Chrome二进制文件

Question

我添加了以下heroku-buildpack: google-chrome an heroku-buildpack-chromedriver，然后设置环境变量

GOOGLE_CHROME_BIN = /app/.apt/opt/google/chrome/chrome
GOOGLE_CHROME_SHIM = /app/.apt/usr/bin/google-chrome-stable

我得到了下面的信息：

Exception Type: WebDriverException
Exception Value:
Message: unknown error: cannot find Chrome binary
(Driver info: chromedriver=2.33.506092 (733a02544d189eeb751fe0d7ddca79a0ee28cce4),platform=Linux 3.13.0-133-generic x86_64)
Exception Location: /app/.heroku/python/lib/python3.6/site-packages/selenium/webdriver/remote/errorhandler.py in check_response, line 194

我正在和它作斗争，不知道我做错了什么？如何知道我是否正确地设置了变量的路径？

现在它可以正常工作了，doe是我所做的步骤，我将环境变量设置如下(你可以从heroku dashbord ->设置中进行设置)

GOOGLE_CHROME_BIN =/app/.apt/opt/google/chrome/google-chrome
GOOGLE_CHROME_SHIM= /app/.apt/opt/google/chrome/google-chrome

然后在我想要运行selenuim的djanogo项目中

from selenium import webdriver
from selenium.webdriver.chrome.options import Options as ChromeOptions

chrome_bin = os.environ.get('GOOGLE_CHROME_SHIM', None)
opts = ChromeOptions()
opts.binary_location = chrome_bin
driver = webdriver.Chrome(executable_path="chromedriver", 
chrome_options=opts)# webdriver.Chrome(DRIVER)
driver.get(url)
....
