无法在 Ruby on Rails 上安装 Puma gem [英] Cannot install Puma gem on Ruby on Rails

问题描述

我正在尝试安装 puma gem，但是当我运行时

I'm trying to install the puma gem, but when I run

gem install puma

我收到此错误消息:

将 gem 'puma' 添加到我的 Gemfile 并运行 bundle install 不是一个选项，因为这不适用于任何 gem 并给我一个错误消息(这是一个单独的问题，我通过通过 gem install 安装它们而使用我使用的其他 gem 规避了这个问题).

Adding gem 'puma' to my Gemfile and running bundle install isn't an option, because that just doesn't work with any gem and gives me an error message (which is a separate issue, one that I've circumvented with the other gems I've used by installing them via gem install).

推荐答案

遇到了同样的问题.

sudo apt-get install libssl-dev
