我使用capybara&selenium测试我的rails项目.当我执行测试脚本时,它有这样的错误
Selenium::WebDriver::Error::WebDriverError:
Could not find Firefox binary (os=macosx). Make sure Firefox is installed or set the path manually with Selenium::WebDriver::Firefox::Binary.path=
但它发生其他错误喜欢
Selenium::WebDriver::Error::WebDriverError:
unable to connect to chromedriver http://127.0.0.1:9515
我是一个菜鸟,因为它涉及Linux设置(和heroku),所以如果这个问题是基本的道歉.
我想在Heroku上运行selenium webkit(在ruby中).我遇到一个困难,我的脚本无法找到Chrome二进制文件.
我实际上让chrome自己工作:
~ $ chromedriver
Starting ChromeDriver 2.22.397932 (282ed7cf89cf0053b6542e0d0f039d4123bbb6ad) on port 9515
Only local connections are allowed.
chromedriver是我复制的文件/app/vendor/bundle/bin/chromedriver,只是为了让它变得更容易.chromedriver文件存在因为我安装了chromedriver-helper gem.gem应该使二进制文件可用于ruby进程,但没有.
我也尝试过显式设置路径,例如Selenium::WebDriver::Chrome.driver_path = 'chromedriver'在我的ruby代码中,上面提到的文件位于根类别中.
这一切都在当地完美运作(有或没有driver_path)
可能是什么原因？我多年前读过这个SO帖子,但它似乎已经过时了.任何想法将不胜感激!

当我在Heroku上运行代码时,我得到了
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

我见过像Heroku这样的帖子: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:
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:
Error Plugin: chromedriver: files attribute must be specified in /Users/leticia/.local/share/heroku/node_modules/chromedriver/package.json
有人可以一步一步地告诉我如何设置必要的构建包以使Watir gem在Heroku中工作吗？
谢谢
更新:
我需要'网络驱动程序',现在我得到了 Selenium::WebDriver::Error::WebDriverError: unable to connect to chromedriver 127.0.0.1:9515.
我已经尝试将env vars配置为:
ENV['GOOGLE_CHROME_BIN'] = "/app/.apt/opt/google/chrome/chrome"
ENV['GOOGLE_CHROME_SHIM'] = "/app/.apt/usr/bin/google-chrome-stable"
并这样做:
