我有一个依赖于project-honeypot
gem的rails应用程序,根据我的Gemfile.lock
,它依次具有以下依赖关系:
net-dns2
packetfu
network_interface
pcarub (~> 0.12)
当我推送到我的heroku应用程序时,它将无法安装pcarub
。 Other sources让我得出结论,我错过了libpcap
和libpcap-devel
。如果我在这里错了,我希望有人会纠正我。
不幸的是,除了heroku buildpacks的复杂性之外,我无法运行任意apt-get
命令。有没有更简单的解决方案?
Heroku / pcarub安装错误:

Heroku buildpacks使用起来非常简单。 Heroku现在提供first class support for multiple buildpacks。我需要明确设置ruby buildpack:
heroku buildpacks:set https://github.com/heroku/heroku-buildpack-ruby.git
然后在ruby buildpack之前添加heroku-buildpack-apt:
heroku buildpacks:add --index 1 https://github.com/ddollar/heroku-buildpack-apt.git
然后我依赖于项目根目录中名为Aptfile
的新文件:
libpcap-dev
下次我部署Heroku时,在运行bundle install之前将新的buildpack用于apt-get install libpcap
。
