看起来我的 mysql2 gem 无法连接到数据库。我可以使用其他 mysql 客户端工具轻松连接到 mysql 数据库。我检查了用于 RSpec 的数据库连接字符串，它是正确的。运行 a_spec.rb 规范文件时出现以下错误。

Failure/Error: @db_client = DBClient.new
     Mysql2::Error::ConnectionError:
       SSL connection error: error:00000001:lib(0):func(0):reason(1)

我在我的机器上运行以下版本的mysql

$ mysql --version
mysql  Ver 8.0.12 for osx10.12 on x86_64 (Homebrew)

我正在使用以下 gem

$ gem which mysql2
/Users/.rvm/gems/ruby-2.3.4/gems/mysql2-0.5.2/lib/mysql2.rb

知道会发生什么吗？想知道有没有人遇到过类似的问题。谢谢！

你能把spec文件贴在这里
还有database.yml 文件。
谢谢@KedarnagMukanahallipatna 我能够解决它。请看下面我的回答。感谢您的帮助。

最后，我能够解决上述 SSL 问题。我所做的只是使用以下命令卸载并重新安装 mysql2 gem。它施展了魔法。

bundle exec gem uninstall mysql2

bundle install
