SyntaxError: Unexpected token import typeORM entity
提问by DeWulf
So, I am working with typeORM and am getting an odd error when I transpile my TypeScript to JavaScript. I am receiving the following error:
因此，我正在使用 typeORM 并且在将我的 TypeScript 转换为 JavaScript 时遇到了一个奇怪的错误。我收到以下错误：
(function (exports, require, module, __filename, __dirname) { import { Entity, PrimaryGeneratedColumn, ManyToOne, OneToMany, TreeChildren, TreeParent, JoinColumn, Column, Tree, TreeLevelColumn } from "typeorm";

What I have tried:
我尝试过的：
- I have tried updating my node.js to the latest (version 8.11.2)
- I have tried changing the "lib" settings in my tsconfig.json in various combinations of "es5", "es6", and "es7"
- I have tried changing the "target" for my tsconfig.json for the targets listed in the above bullet point.
- I have tried changing the import statements in my entity files from "import (lib) from (module)" to "const (lib) require (module)"; However, this causes more issues and doesn't work well.
- 我尝试将 node.js 更新到最新版本（8.11.2 版）
- 我曾尝试以“es5”、“es6”和“es7”的各种组合更改 tsconfig.json 中的“lib”设置
- 我已经尝试为上面列出的目标更改 tsconfig.json 的“目标”。
- 我尝试将实体文件中的导入语句从“import (lib) from (module)”更改为“const (lib) require (module)”；但是，这会导致更多问题并且效果不佳。
I have been googling for this issue extensively and it has left me scratching my head. Any and all help would be greatly appreciated.
我一直在广泛地搜索这个问题，这让我摸不着头脑。任何和所有的帮助将不胜感激。

Alright, I am simply dumb.
好吧，我就是傻。
So, the ormconfig.json points your entities to your ts files in your /src folder. When you build your project, it should point to where your entities are. I did think it was odd that it was trying to reference a TS file after building.
因此，ormconfig.json 将您的实体指向 /src 文件夹中的 ts 文件。当您构建项目时，它应该指向您的实体所在的位置。我确实认为它在构建后尝试引用 TS 文件很奇怪。
ormconfig.json
ormconfig.json

"type": "postgres",
"host": "**********************",
"port": 5432,
"username": "**************",
"password": "*************",
"database": "*************",
"synchronize": true,
"logging": false,
"entities": [
// changed this
"dist/entity/*.js"
],
"migrations": [

],
"subscribers": [
"src/subscriber/**/*.ts"
],
"cli": {
"entitiesDir": "src/entity",
"migrationsDir": "src/migration",
"subscribersDir": "src/subscriber"
}
}

You can also use ts-nodeto run typeorm, which will allow you to run tsfiles, and which will allow you to avoid compiling and running separate jsfiles.
您还可以使用ts-node运行 typeorm，这将允许您运行ts文件，并允许您避免编译和运行单独的js文件。
Per this github comment, you can do the following:
根据此 github 评论，您可以执行以下操作：
1.- Install ts-node and typescript globally:
$ npm install -g ts-node typescript2.- Execute the typeorm command with ts-node:
$ ts-node ./node_modules/.bin/typeorm migrations:generate -n
1.- 全局安装 ts-node 和 typescript：
$ npm install -g ts-node typescript2.- 使用 ts-node 执行 typeorm 命令：
$ ts-node ./node_modules/.bin/typeorm migrations:generate -n
If you're on windows, you'll have problems with that. Per this comment, you'll want to directly reference cli.js:
如果你在windows上，你会遇到问题。根据此评论，您需要直接参考cli.js：
ts-node node_modules\typeorm\cli.js
ts-node node_modules\typeorm\cli.js

I had a similar issue and was also being dumb. I had accidentally used the .jsextension to name the file instead of .ts
我有一个类似的问题，也很愚蠢。我不小心使用.js扩展名来命名文件而不是.ts
回答by oded
it happened to me too, the problem occurred because i've accidently imported 'BaseEntity' from 'typeorm/browser' instead of 'typeorm'.
它也发生在我身上，出现问题是因为我不小心从“typeorm/browser”而不是“typeorm”导入了“BaseEntity”。
the first one is js file, and the second is ts file.
第一个是js文件，第二个是ts文件。
