我无法运行“软件包更新”由于“mysql2”宝石 [英] I can't run "bundle update" because of "mysql2" gem

问题描述

  gem'mysql2'
  

但是，当我运行捆绑更新时，出现以下错误消息：

 安装mysql2（0.3.16）时发生错误，并且Bundler无法继续。 
确保`gem install mysql2 -v'0.3.16'`捆绑成功。 
  

我试图将它移入生产部分，如下所示：

  group：production do 
 gem'mysql2'
 end 
  

但是运行捆绑更新后，结果是一样的。如何摆脱本地主机上的这个错误信息？

解决方案<在Ubuntu上运行

  sudo apt-get install libmysqlclient-dev 
  

或者，如果您使用MariaDB，请运行

  sudo apt-get install libmariadbclient-dev 
  

I have this in the Gemfile:

gem 'mysql2'

But when I run bundle update, I get this error message:

An error occurred while installing mysql2 (0.3.16), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.3.16'` succeeds before bundling.

I've tried to move this into the production section, like this:

group :production do
  gem 'mysql2'
end

But after running bundle update, the result is the same. This section is processed only in the production mode, or not?

How to get rid of this error message on localhost?
