这里是mysql2的gem文件入口

Here is the gem file entry for mysql2

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '~> 5.1.1'
# Use mysql as the database for Active Record
gem 'mysql2', '>= 0.3.18', '< 0.5'
# Use Puma as the app server
gem 'puma', '~> 3.7'

有什么帮助吗?

推荐答案

目前没有适用于 Windows 的 Ruby 2.4 的 mysql2 二进制文件.所以我卸载了 ruby​​ 2.4 并安装了 ruby​​ 2.3.现在它运行良好

There is no mysql2 binary for Ruby 2.4 for Windows available at this time. So i uninstall ruby 2.4 and install ruby 2.3. Now it is working well
