无法生成迁移

Question

我有一个项目使用 typeorm 来创建数据库。当我执行命令来生成到我的项目的迁移时，它给了我错误

我有以下 orm 配置 json 文件：

 {
   "type": "postgres",
   "host": "localhost",
   "port": 5432,
   "username": "postgres",
   "password": "",
   "database": "postgres",
   "synchronize": true,
   "logging": false,
  "entities": [
    "src/entity/**/*.ts"
  ],
   "migrations": [
      "src/migration/**/*.ts"
   ],
   "subscribers": [
      "src/subscriber/**/*.ts"
   ],
   "cli": {
      "entitiesDir": "src/entity",
      "migrationsDir": "src/migration",
         "subscribersDir": "src/subscriber"
        }
    }

我有这个用户实体类：

import { Entity, PrimaryGeneratedColumn, Column, OneToMany } from "typeorm";
import { Transaction } from "./Transactions";
export type UserStatus = "Active" | "Inactive";

@Entity()
export class User {

@PrimaryGeneratedColumn()
id: number;

@Column("varchar",{
    length:50
})
account_id: string;

@Column("varchar",{
    length: 50
})
name: string;

@Column("varchar",{
    length:50
})
email: string;

@Column("varchar",{
    length:15
})
phone_number: string;

@Column("varchar",{
    length:50
})
address: string;

@Column({
    type: "enum",
    enum: ["Active", "Inactive"]
}) status: UserStatus;


@Column("varchar",{
    length:50
})
current_id: string;

@OneToMany(type => Transaction, transaction => transaction.user)
transactions: Transaction[];

}

如果我执行命令来生成迁移，则会出现以下错误：

C:\Users\Firdaus97\source\repos\Cust Local payment\Cust Local payment\MyProject>ts-node ./node_modules/.bin/typeorm migrations:generate -n
C:\Users\Firdaus97\source\repos\Cust Local payment\Cust Local payment\MyProject\node_modules\.bin\typeorm:2
basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')")
          ^^^^^^^

Answer 1

我在Windows 10上遇到了这个问题，并且能够按照此答案和此评论修复它：

在我package.json之前的脚本中

  "scripts": {
    ...
    "typeorm": "ts-node -r tsconfig-paths/register ./node_modules/.bin/typeorm",
    "migration:generate": "npm run typeorm migration:generate -- -n",
  }

我将“typeorm”替换为

  "scripts": {
    ...
    "typeorm:win": "ts-node -r tsconfig-paths/register node_modules\\typeorm\\cli.js",
    "migration:generate:win": "npm run typeorm:win migration:generate -- -n"
  }

然后这就像一个魅力npm run migration:generate:win -n <<migration name>>

Answer 2

从您的命令中删除ts-node并重试：

.\node_modules\.bin\typeorm migrations:generate -n

typeorm在你的 node_modules 中已经是一个可执行文件，你不必使用ts-node，这仅适用于 TypeScript 文件。

其他解决方案：

1. npm 脚本：

在您的中创建一个脚本package.json：

{
  "scripts": {
    "migrate": "typeorm migrations:generate -n"
  }
}

使用 npm 运行它：

{
  "scripts": {
    "migrate": "typeorm migrations:generate -n"
  }
}

2. 使用npx

从5.2npm 版本开始，你可以这样做：

npm run migrate

3. 使用yarn

npx typeorm migrations:generate -n
