TypeORM Cli：migrationsDir似乎被脚本忽略

标签： database-migration typeorm

我正在尝试完成一个简单的迁移-重命名users表中的一列。 我无法使用clis使用migrationsDir来创建或运行迁移。

迁移创建

当我跑步时 npm run typeorm:cli -- migration:create -n UserFullName -d 'server/migration，在迁移文件夹中创建文件没有问题。

不使用-d参数创建迁移只会在文件夹根目录中创建文件，而忽略连接选项中的migrationsDir（请参见下面的ormconfig.ts）。

正在迁移

运行npm run typeorm:cli -- migration:run会产生退出状态1，我的猜测是找不到迁移，但我真的不知道。

Error during migration run:

我怀疑我的文件结构可能与此问题有关，因此我将其简要列出。我只是列出了一些基础知识，还有更多用于锦标赛，摔跤手，排名，排名表的控制器和实体。

我认为这里的问题是因为您使用异步连接。在添加具有同步连接的ormconfig.ts（也应与.js一起使用）文件后，我遇到了相同的问题并设法解决了这个问题。

在配置文件中，您应该添加cli属性cli: {migrationsDir: "server/migration"}

要使用cli运行迁移，还需要另一个属性：migrations: [join(__dirname, 'server/migration/*{.ts,.js}')],

另外，在运行cli时，您还应该指出此配置文件的位置--config path/to/ormconfig.ts标志。

带有ts的完整命令示例：ts-node ./node_modules/typeorm/cli.js migration:generate --config server/ormconfig.ts

有关更多信息，您可以查看此示例https://github.com/ambroiseRabier/typeorm-nestjs-migration-example，我发现它非常有用。

从您的文件结构看来，配置应如下所示：

ormconfig.ts 

export const config: TypeOrmModuleOptions = {
    ...
    migrations: ['server/migration/*.js', 'server/migration/*.ts'],
    cli: {
        migrationsDir: 'server/migration',
    },
};

您可能需要从ormconfig.ts文件夹中取出server文件，使其与package.json位于同一级别。

对于遇到类似问题的任何人，这些都是我重视的重要矿块：

  1. 仅当创建迁移（不读取）时，typeorm CLI才会从ormconfig.ts中读取cli.migrationsDir。您可以看到细微的区别here in the docs-它显示为：

    “ ... "cli": { "migrationsDir": "migration" }-表示 CLI必须在“迁移”目录中创建新的迁移。”

  2. 这令人困惑-为什么只需要编写一个单独的配置？读/写迁移不会是相同的配置吗？我不知道，仍然不知道-但是我也通过阅读源代码来确认了这一点（除非我发了些什么）。

  3. 最终结论：除非您有充分的理由，否则这些配置（migrations: [...]和cli.migrationsDir）可能指向文件系统上的相同位置。

干杯。

答案 3 :(得分：-2)

您是否到达了正确的迁移文件路径？

{
    cli: {
        migrationsDir: "src/migration"
    }
}
