我在 google 上搜索了这个问题一段时间，在 typeorm github 上找到了几篇帖子，但它们都被关闭了，没有提供解决方案。这似乎是一个 webpack 问题，但我不明白问题到底是什么。该示例对我来说编译得很好。
当我调用从 typeorm 导入的 createConnection 时，就会发生这种情况。我得到的错误如下。我已经删掉了大部分“无法解决......”的内容，但你明白了。

感谢任何帮助!
最佳答案
我在设置项目时遇到了同样的问题。
要解决此问题，您可以将以下插件添加到您的 webpack 配置中，以删除您不想使用的插件的警告
new FilterWarningsPlugin({
exclude: [/mongodb/, /mssql/, /mysql/, /mysql2/, /oracledb/, /redis/, /sqlite3/, /sql.js/, /react-native-sqlite-storage/]
})
希望对你有帮助:)
