Question

我尝试在rake db：migrate中输入以创建迁移，但我的rake已中止并给我这个声明。你能解释一下为什么会这样吗？

Answer 1

您的mysql软件包无法正确安装该命令

sudo apt-get install mysql-server mysql-common mysql-client

如果这不起作用，请安装此

sudo apt-get install libmysql-ruby libmysqlclient-dev

Answer 2

根据您的问题，我发现您使用的是Macintosh。因此，请尝试以下方法：

在终端

mysql_install_db

在终端

mysql.server start

如果这不起作用，请结帐Installing mysql2 gem for Ruby on Rails with Mac OSX 10.6

为什么我的rake db：migrate无法响应？
