Heroku：使用Selenium时找不到chromedriver [英] Heroku: Unable to find chromedriver when using Selenium

问题描述

我有一个执行此操作的Ruby代码：

I have a Ruby code that does this:

browser = Watir::Browser.new(:chrome, switches: switches, headless: true)
browser.goto(....)

当我在Heroku上运行代码

When I run the code on Heroku I get

Selenium::WebDriver::Error::WebDriverError:  Unable to find chromedriver. Please download the server from http://chromedriver.storage.googleapis.com/index.html and place it somewhere on your PATH. More info at https://github
.com/SeleniumHQ/selenium/wiki/ChromeDriver.

我见过类似 Heroku：使用Watir / Selenium时无法连接到chromedriver 127.0.0.1:9515
，但我不知道如何正确配置buildpacks。我尝试过的
：

I've seen posts like Heroku: unable to connect to chromedriver 127.0.0.1:9515 when using Watir/Selenium but I don't know how to properly configure the buildpacks. I've tried with:

heroku buildpacks:set https://github.com/heroku/heroku-buildpack-google-chrome
heroku buildpacks:set https://github.com/heroku/heroku-buildpack-chromedriver

，但是当我尝试将更改推送到Heroku时，我得到：

but then when I try to push the changes to Heroku I get:

Error Plugin: chromedriver: files attribute must be specified in /Users/leticia/.local/share/heroku/node_modules/chromedriver/package.json

$ b $中指定files属性b

有人可以逐步指导我如何设置必要的buildpack，以使Watir gem在Heroku中工作吗？

Can someone give me a step by step on how to set the necessary buildpacks to make the Watir gem work in Heroku?

谢谢

更新：

我需要'webdrivers'，现在我得到 Selenium :: WebDriver :: Error :: WebDriverError：无法连接到chromedriver 127.0.0.1:9515 。

I've required 'webdrivers' and now I'm getting Selenium::WebDriver::Error::WebDriverError: unable to connect to chromedriver 127.0.0.1:9515 .

我已经尝试将环境变量配置为：

I've tried configuring the env vars to:

ENV['GOOGLE_CHROME_BIN'] = "/app/.apt/opt/google/chrome/chrome"
ENV['GOOGLE_CHROME_SHIM'] = "/app/.apt/usr/bin/google-chrome-stable"

并执行以下操作：

options = Selenium::WebDriver::Chrome::Options.new
chrome_bin_path = ENV.fetch('GOOGLE_CHROME_SHIM', nil)
options.binary = chrome_bin_path if chrome_bin_path 
options.add_argument('--headless')
driver = Selenium::WebDriver.for :chrome, options: options

，但最后还是出现错误线。

but I'm still getting the error in the last line.

更新2：

我搬到了Dokku而不是Heroku，我得到了同样的错误。 Selenium :: WebDriver :: Error :: WebDriverError：无法连接到chromedriver 127.0.0.1:9515 。

I moved to Dokku instead of Heroku and I get the same error. Selenium::WebDriver::Error::WebDriverError: unable to connect to chromedriver 127.0.0.1:9515.

推荐答案

方法是：

1. 使用以下方法添加构建包

1. Add the buildpacks with

heroku buildpacks:add https://github.com/heroku/heroku-buildpack-google-chrome
heroku buildpacks:add https://github.com/heroku/heroku-buildpack-chromedriver

添加环境变量Heroku中的 GOOGLE_CHROME_BIN 和 GOOGLE_CHROME_SHIM 都具有值 /app/.apt/opt/google/ chrome / chrome 即

heroku config:set GOOGLE_CHROME_BIN=/app/.apt/opt/google/chrome/chrome
heroku config:set GOOGLE_CHROME_SHIM=/app/.apt/opt/google/chrome/chrome

按以下方式使用watir

Use watir in the following way

args = %w[--disable-infobars --headless window-size=1600,1200 --no-sandbox --disable-gpu]
options = {
       binary: ENV['GOOGLE_CHROME_BIN'],
       prefs: { password_manager_enable: false, credentials_enable_service: false },
       args:  args
     }    
@browser = Watir::Browser.new(:chrome, options: options)
