模块“typeorm”没有导出成员“DataSource”和“DataSourceOptions”

Question

我收到错误，Module '"typeorm"' has no exported member 'DataSource'.而.Module '"typeorm"' has no exported member 'DataSourceOptions'.nest build

npm install 之后，我使用nest build命令行命令构建了 Nestjs 应用程序，但出现了这些错误。

typeorm版本是“^0.2.25”，“@nestjs/typeorm”：“^8.0.2”，

无法弄清楚为什么会发生这种情况。

const DATABASE_SSL_CA = process.env.DATABASE_SSL_CA;

我通过指定固定包版本修复了此错误：

"@nestjs/typeorm": "8.0.2",
"typeorm": "0.2.45",
