Problems Installing puma ruby gem on OS X El Capitan 10.11

问题 When attempting to install puma "any version" on OS X El Capitan it kept failing. Thankfully, /user/dennis-best was able to shed some light and deserves all the credit for this. 回答1: For people who are having issues with puma and openssl, particularly with Mac OS 10.11 (El Capitan), adding some flags will save you hours and hours of heartache: gem install puma -- --with-cppflags=-I/usr/local/opt/openssl/include --with-ldflags=-L/usr/local/opt/openssl/lib https://gist.github.com/edvinasbartkus

问题 I have a Rails 4 API project on GitHub, and I'm trying to deploy it from my MacBook Pro using Capistrano 3 to two Amazon AWS EC2 Ubuntu instances using SSH keys - one is the app/web server, and the other is the PostgreSQL database server.

These are the relevant gems I'm using: gem 'capistrano', '~> 3.0.0' gem 'capistrano-rails' gem 'capistrano

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> --------------------------------------------------------------------【可能出现的问题及解决】 Seems like you have 10.0.2.2 in your localhosts. You can check it in /etc/hosts . It may look like ... 127.0.0.1 localhost 10.0.2.2 localhost ... If you don't need 10.0.2.2 here and you don't know why you got it (your case =)) you can remove this line and try to run rails s again. Maybe you would have to restart your network system or you can reboot. Another way would be running rails server on particular host like rails s -b 127.0.0.1 I don't know exact reasons of the problem
