dynogels总是告诉我无效的模式内容，即使在使用它的github示例时也是如此。

Question

我正在尝试使用髁状凝胶作为DynamoDB的ORM，但是即使是最简单的示例也无法工作。无论我做什么，类型记录在我尝试使用它的时候都会抛出“无效模式内容”错误。

运行命令

ts-node main.ts 

main.ts

import * as Dynogels from "dynogels";
import * as Joi from "joi";

// this comes out of an example on the dynogels github page
var BlogPost = Dynogels.define('BlogPost', {
  hashKey : 'email',
  rangeKey : 'title',
  schema : {
    email   : Joi.string().email(),
    title   : Joi.string(),
    content : Joi.string(),
    tags   : Dynogels.types.stringSet(),
  }
});

console.log("this doesn't work")

package.json

{
  "name": "stackoverflowpost",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "@types/dynogels": "^9.0.3",
    "@types/joi": "^14.3.4",
    "dynogels": "^9.1.0",
    "joi": "^17.2.0",
    "typescript": "^3.9.7"
  }
}

当我跑的时候

StackOverflowPost/node_modules/dynogels/node_modules/joi/node_modules/hoek/lib/index.js:740抛出新的错误(msgs.join(‘') \’未知错误‘)；^ Error:无效模式内容: at (/Users/stephencuzzort/Projects/StackOverflowPost/node_modules/dynogels/node_modules/joi/node_modules/hoek/lib/index.js:740:11) at Object.exports.schema (/Users/stephencuzzort/Projects/StackOverflowPost/node_modules/dynogels/node_modules/joi/lib/cast.js:55:10) at internals.Object.keys (/Users/stephencuzzort/Projects/StackOverflowPost/node_modules/dynogels/node_modules/joi/lib/types/object/index.js:352:35) at (/Users/stephencuzzort/Projects/StackOverflowPost/node_modules/dynogels/node_modules/joi/lib/cast.js:36:29) at internals.Object.keys (/Users/stephencuzzort/Projects/StackOverflowPost/node_modules/dynogels/node_modules/joi/lib/types/object/index.js:352:35) at Object.exports.schema (/Users/stephencuzzort/Projects/StackOverflowPost/node_modules/dynogels/node_modules/joi/lib( (/Users/stephencuzzort/Projects/StackOverflowPost/node_modules/dynogels/node_modules/joi/lib/types/object/index.js:352:35) at Joi.validate (/Users/stephencuzzort/Projects/StackOverflowPost/node_modules/dynogels/lib/schema.js:121:71) at internals.Object._validateWithOptions (/Users/stephencuzzort/Projects/StackOverflowPost/node_modules/dynogels/node_modules/joi/lib/types/any/index.js：)666:20)在(/Users/stephencuzzort/Projects/StackOverflowPost/node_modules/dynogels/node_modules/joi/lib/index.js:139:23) module.exports.internals.Any.root.validate

为什么当我使用github页面中的一个示例时，我仍然会得到它呢？我怎样才能让这个例子奏效呢？

发现问题了。这是joi版本的错配。

您需要确保joi版本完全匹配，或者从dynogels node_modules导入。

*作为Joi从“dynogels/node_modules/joi”中导入；

帮我修好了。
