Watir应用程序部署到heroku

皇族灬柒诺彡_241 发布于 2022-12-15 15:19

我正在尝试使用Watir webdriver将应用程序部署到Heroku.它在本地成功运行.根据这个问题的答案:你能在Heroku上部署Watir来生成HTML快照吗？如果是这样,怎么样？, 你能行的.我按照这个答案的步骤/sf/ask/17360801/.我的app.rb看起来像这样:

require "sinatra"
require "rubygems"
require "shotgun"
require "rake"
require "watir"

get '/sending_out' do 
    browser = Watir::Browser.new :phantomjs
    erb :index
end

但是当使用这些日志部署到Heroku时它会崩溃:

而当我把它推到Heroku时,它认为这是一个幻想应用程序:

PhantomJS app detected

可以做些什么呢？这是否可以从Heroku运行Watir？

编辑:Heroku支持的答案:

Watir需要selenium,这需要在机器上安装X服务器.因为我们的dynos不是为了启动图形应用程序,所以它们没有安装任何X服务器,因此无法安装Selenium.因此,我担心在您的应用程序中使用Watir是不可能的.

对的,这是可能的!只需按照本文中的步骤操作:https://github.com/edelpero/watir-examples/blob/master/watir_on_heroku.md.

不久:

$ heroku config:set BUILDPACK_URL=https://github.com/ddollar/heroku-buildpack-multi.git
$ touch .buildpacks

然后添加到新创建的目录.buildpacks这些行:

https://github.com/heroku/heroku-buildpack-ruby
https://github.com/stomita/heroku-buildpack-phantomjs

然后在终端:

$ heroku config:set PATH="/usr/local/bin:/usr/bin:/bin:/app/vendor/phantomjs/bin"
$ heroku config:set LD_LIBRARY_PATH=/usr/local/lib:/usr/lib:/lib:/app/vendor/phantomjs/lib

然后将这些更改推送到Heroku,并且

Watir::Browser.new :phantomjs

使用通常的Watir代码应该工作!
