Question

当我运行使用sequelize库与MSSQL数据库连接的节点应用程序时，出现此错误。

我尝试在本地和全局手动安装繁琐的操作，但错误仍然存在。

错误的完整堆栈如下：

Answer 1

请将其添加到您的 packege.json 文件中。

似乎sequalize使动态需要调用乏味。

"bin": "index.js",
"pkg": {
    "scripts": ["node_modules/tedious/lib/tedious.js", "models/*.js"],
    "assets": ["config/log.json"]
  }

您可以找到完整的说明here。它对我有效。

要开始解决此问题，您必须确保已安装 sequelize 和 tedious，并且它们的名称出现在 package.json 中的依赖项中。同样，如果您使用打字稿，则必须在 devDependencies 中添加 @types/node、@types/tedious 和 @types/validator。

只需运行即可

yarn add sequelize
yarn add tedious
yarn add -D @types/node
yarn add -D @types/tedious
yarn add -D @types/validator

那么您的 package.json 应如下所示：

"dependencies": {     
  ...
  "sequelize": "^6.6.2",
  "tedious": "^11.0.8"
},
"devDependencies": {
  "@types/node": "^14.6.2",
  "@types/tedious": "^4.0.3",
  "@types/validator": "^13.1.3",

最后但更重要的是导入 tedious 并将其添加到 sequelize 配置选项作为 dialectModule 像这样：

import { Sequelize } from 'sequelize';
import * as tedious from 'tedious';

...

const config = {
  username: 'user',
  password: 'pass',
  database: 'db',
  host: 'host',
  dialect: 'mssql',
  dialectModule: tedious, //   <----   <---- this is the key!!
  define: { underscored: true },
  dialectOptions,
};

...

const sequelize = new Sequelize(config.database, config.username, config.password, config);

享受！！ :D

错误：请手动安装乏味的软件包
