Is this related to my MySql installation? 这与MySql安装有关吗?
尝试:
gem install mysql2 -- --with-mysql-config=/Applications/MAMP/Library/bin/mysql_config
I've fixed this by simply running gem install using the mysql config an existing config. 我通过使用mysql配置现有配置运行gem install来解决这个问题。
gem install mysql2 -v {mysql2_gem_version} -- --with-mysql-config=/usr/local/Cellar/mysql/{mysql_gem_version}/bin/mysql_config
gem install mysql2 -v '0.3.17' -- --with-mysql-config=/usr/local/Cellar/mysql/5.6.21/bin/mysql_config
Try this: 尝试这个:
First add the below dependencies by using below commands: 首先使用以下命令添加以下依赖项:
sudo apt-get install mysql-server-5.5
sudo apt-get install mysql-client libmysqlclient-dev
sudo apt-get install libmysqld-dev libmysqlclient-dev mysql-client
Finally Add gem 'mysql2', '~> 0.3.16'
in Gemfile and bundle install 最后在Gemfile中添加
'mysql2', '~> 0.3.16'
并捆绑安装
