我试图让以下示例工作https://github.com/typeorm/javascript-example/tree/master/src/app3-es6
我遇到了以下错误
连接时Connection.findRepositoryAggregator(... \ node_modules \ typeorm \ connection \ Connection.js:513:19)中的新RepositoryNotFoundError(... \ node_modules \ typeorm \ connection \ error \ RepositoryNotFoundError.js:24:23)出错.getRepository(... \ node_modules \ typeorm \ connection \ Connection.js:405:21)at ... \ index.js:27:37
name: 'RepositoryNotFoundError',
message: 'No repository for "Post" was found. Looks like this entity is not registered in current "default" connection?'
这是index.js
const typeorm = require("typeorm"); // import * as typeorm from "typeorm";
const Post = require("./model/Post"); // import {Post} from "./model/Post";
// import Post from './model/Post.js';
const Category = require("./model/Category"); // import {Category} from "./model/Category";
typeorm.createConnection({
driver: {
type: "oracle",
host: "localhost",
port: 1521,
username: "uname",
password: "pwd",
sid: "dev"
},
entities: [
__dirname + "/entity/*.js"
],
autoSchemaSync: true
}).then(function (connection) {
console.log(connection);
let post = new Post.Post();
post.title = "Control flow based type analysis";
post.text = "TypeScript 2.0 implements a control flow-based type analysis for local variables and parameters.";
post.categories = [new Category.Category(0, "TypeScript"), new Category.Category(0, "Programming")];
let postRepository = connection.getRepository(Post.Post);
postRepository.persist(post)
.then(function(savedPost) {
console.log("Post has been saved: ", savedPost);
console.log("Now lets load all posts: ");
return postRepository.find();
})
.then(function(allPosts) {
console.log("All posts: ", allPosts);
});
}).catch(function(error) {
console.log("Error: ", error);
});
post.js in / model /
/*export */ class Post {
constructor(id, title, text, categories) {
this.id = id;
this.title = title;
this.text = text;
this.categories = categories;
}
}
module.exports = {
Post: Post
};
Category.js
/*export */ class Category {
constructor(id, name) {
this.id = id;
this.name = name;

}
module.exports = {

/ entity /中的PostSchema.js
const Post = require("../model/Post"); // import {Post} from "../model/Post";
const Category = require("../model/Category"); // import {Category} from "../model/Category";
const PostSchema = {

我不知道我做错了什么
看起来您的实体导入无效。如果您通过通配符导入:
entities: [
__dirname + "/entity/*.js"
],`
确保您的模型编译为js。你也可以导入
createConnection({
...,
entities: [
Post,
...
],}).then(...)
