安装后配置了pg的数据库怎么启动？

[zhangsai521314]

我的数据库配置
database: { // 数据库名称 db: 'npm', //数据库用户名 username: 'postgres', //数据库用户密码 password: '12', //数据库类型支持： 'mysql', 'sqlite', 'postgres', 'mariadb' dialect: 'postgres', //数据库ip host: '172.21.0.17', //数据库端口 port: 5422, // use pooling in order to reduce db connection overload and to increase speed // currently only for mysql and postgresql (since v1.5.0) pool: { maxConnections: 10, minConnections: 0, maxIdleTime: 30000 }, // the storage engine for 'sqlite' // default store into ~/.cnpmjs.org/data.sqlite storage: path.join(dataDir, 'data.sqlite'), logging: !!process.env.SQL_DEBUG, },
在使用 cnpmjs.org start启动时报下面的错误：
`/bkdata/npm/nodejs/node_global/lib/node_modules/cnpmjs.org/node_modules/sequelize/lib/dialects/postgres/connection-manager.js:27
throw new Error('Please install '' + (sequelize.config.dialectModulePath || 'pg') + '' module manually');
^
