知道是什么问题吗...？
【问题讨论】：
【参考方案1】：@nestjs/mongoose@7.2.2 似乎不适用于mongoose 版本>=5.11.11。
解决方案
降级到 5.11.10 就可以了。
npm install mongoose@5.11.10
npm uninstall @types/mongoose
（uninstall 行适用于来自 Google 的用户，您似乎已经删除了仅适用于 Mongoose 5.10 及以下版本的 @types/mongoose 包）
原因
从 Mongoose 5.11 开始，类型包含在 Mongoose 中。因此，类型差异很少。
自从类型被转移以来，已经有一个TON of bugs 提交了关于此的文件。 还有更多here 和here。
替代解决方案
降级 Mongoose 软件包
如果你遇到更多问题，你也可以降级你的 mongoose 相关包
npm i @nestjs/mongoose@7.1.2 mongoose@5.10 @types/mongoose@5.10
禁用依赖类型检查
如果你真的可以通过在tsconfig.json 中添加这一行来跳过对node_modules 的类型检查
"skipLibCheck": true,
标准警告适用。
一般警告
作为一般说明，具有单个提交和 0 星的 GitHub 代码通常不被视为生产就绪。特别是当它基于一个 9 星的存储库时，它会复制和修改代码而不是重新打包（使合并修复更加困难）。
话虽如此，这里可能有一些不错的工作。
