英文:

MongoDB doesn't connect. [MongooseServerSelectionError: connect ECONNREFUSED ::1:27017]

问题

以下是翻译好的部分：

以下是来自index.js文件的代码：

const mongoose = require("mongoose");
mongoose.connect("mongodb://localhost/db_c");

Nodjs版本： v18.13.0

MongoDB版本： 6.0.5

Mongoose版本： 7.2.2

我遇到的错误是：

我还遇到了与 node 18.16.0 相似的连接问题。我将它降级到了 16.13.0，然后它正常工作了。
**编辑**：
我已经让它在 node 18.16.0 上工作了。从 node 17 开始有一个重大变化，它默认使用 IPv6 而不是 IPv4。我不得不修改我的 mongod.conf 文件以适应这一变化。这些指令相当简单（https://www.mongodb.com/docs/manual/reference/configuration-options/#net-options）。我使用的是 node 驱动程序，而不是 mongoose。与数据库版本的兼容性也有一些问题，我也不得不解决这些问题。

I also had the similar connection problem with node 18.16.0. I downgraded it to 16.13.0, and it worked fine.
**Edit**:
I got it to work with node 18.16.0. There is a breaking change starting node 17 that it uses IPv6 instead of IPv4 as default. I had to modify my mongod.conf for that. The instructions are quite simple (https://www.mongodb.com/docs/manual/reference/configuration-options/#net-options). I am using node driver not mongoose. There are issues with compatibility with version of DB that I also had to work out.
