加重方言错误
我最近在安装lodash后遇到了一个奇怪的错误。 我不知道它是否对我的设置产生了任何影响，但是突然之间的sequelize会在mysql不支持的方言属性上抛出一个错误，并且无法读取property 'dialectName' of undefined 。 我不知道为什么发生这种情况，因为我一直在使用sequelize，而这一直没有出现。
运行节点v0.10.40
完整的错误：
/sequelize/lib/sequelize.js:205 throw new Error('The dialect ' + this.getDialect() + ' is not supported. S ^ Error: The dialect mysql is not supported. Supported dialects: mariadb, mssql, mysql, postgres, and sqlite.

我的方言在哪里：
DB-index.js：
var Sequelize = require('sequelize'); var path = require('path'); var config = require(path.resolve(__dirname, '..', '..','./config/config.js')); var sequelize = new Sequelize(config.database, config.username, config.password, { host:'localhost', port:'3306', dialect: 'mysql' }); sequelize.authenticate().then(function(err) { if (!!err) { console.log('Unable to connect to the database:', err) } else { console.log('Connection has been established successfully.') } }); var db = {} db.Member = sequelize.import(__dirname + "/member"); db.Organization = sequelize.import(__dirname + "/organization"); db.User = sequelize.import(__dirname + "/user"); db.DiscoverySource = sequelize.import(__dirname + "/discovery-source"); db.User.associate(db); db.Organization.associate(db); db.DiscoverySource.associate(db); db.sequelize = sequelize; db.Sequelize = Sequelize; sequelize.sync(); module.exports = db;
的package.json：
{ "name": "app-test", "version": "1.0.0", "description": "", "engines": { "node": "5.0.0" }, "main": "app.js", "scripts": { "test": "echo \"Error: no test specified\" && exit 1" }, "keywords": [], "author": "", "license": "ISC", "dependencies": { "bcrypt-nodejs": "0.0.3", "body-parser": "^1.14.1", "cheerio": "^0.20.0", "connect-flash": "^0.1.1", "cookie-parser": "^1.4.0", "express": "^4.13.3", "express-hbs": "^0.8.4", "jquery": "^2.2.0", "lodash": "^4.2.1", "moment": "^2.10.6", "morgan": "^1.6.1", "mysql": "^2.9.0", "nodemon": "^1.8.1", "passport": "^0.3.2", "passport-local": "^1.0.0", "sequelize": "^3.14.1", "session": "^0.1.0" } }
你必须安装pakage mysql：
npm install mysql --save
祝你好运^^
