javascript - sequelize引发ER_CANT_CREATE_TABLE:无法创建表“SequelizeMeta”(错误号:30)

Sequelize无法创建其元表，原因如下：

$ sequelize db:migrate

Sequelize [Node: 6.10.2, CLI: 2.7.0, ORM: 3.30.4]

Loaded configuration file "config\config.json".
Using environment "development".

即使我直接使用SQL命令，它仍然不起作用：

mysql> CREATE TABLE IF NOT EXISTS `SequelizeMeta` (`name` VARCHAR(255) NOT NULL UNIQUE , UNIQUE `SequelizeMeta_name_unique` (`name`), PRIMARY KEY (`name`)) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE utf8_unicode_ci;
1005 - Can't create table 'SequelizeMeta' (errno: 30)

你知道是什么引起的吗？

最佳答案

errno: 30linux代表只读文件系统吗。显然，这不能通过在sequelize中更改任何内容来解决：）
您必须更正文件系统权限，否则同样可能是文件系统已损坏，操作系统已关闭写入以防止进一步损坏。
