问题描述
我在 Rails v3.2.22.5 上运行 Ruby v2.3.5，但无法在 ubuntu 20.04 上安装 MysqL2 v0.3.20
我不断收到 "Failed to build gem extension" 错误。
nb：选择的版本都是项目所必需的，所以我无法更改它们。
关于如何最好地进行的任何想法？我已经尝试安装更高版本的 MysqL2 版本（例如 0.5.x），它安装得很好，但我当前的项目要避免这种情况。
不需要更新 rails 或 MysqL2 的解决方案将是理想的。
在我的 Gemfile 中是 gem 'MysqL2','0.3.20'
接下来我运行 gem install MysqL2 -v '0.3.20' --source 'https://rubygems.org/'
返回：
