控制台中的日志显示[12:06:59 PM]检测到文件更改.在nestjs中启动增量编译

Question

当我启动嵌套应用程序时，它会成功启动并显示下面给出的日志。

我已使用命令npm run dev:start启动该项目。

[11:55:17 AM] File change detected. Starting incremental compilation...
[11:55:17 AM] Found 0 errors. Watching for file changes.

现在，如果我向端点发送任何请求，它会成功地发送请求，数据会存储在数据库中，还会返回数据，但问题是代码会被重新编译，并在控制台中显示

[12:06:59 PM] File change detected. Starting incremental compilation...

并且它不显示日志消息。我该怎么解决这个问题？

Answer 1

添加到您的tsconfig.json:

"include": [
"src"
]

Answer 2

如果以上不起作用，以下是我如何修复问题

这与你的操作系统(在我的情况下是Windows 11(和ts 4.9 有关

请在包.json include 中使用typescript 4.8进行尝试

"devDependencies": {
...,
"typescript": "4.8.3",
...
}

后期

npm i
npm run start:dev

Answer 3

如Windows操作系统中Typescript版本9+的NestJs文档中所述，我们需要在tsconfig文件中的compilerOptions之后添加以下内容：

"watchOptions"：{"watchFile"："固定轮询间隔"；}

Answer 4

如果以上不起作用，以下是我如何修复问题

对于NestJS

在：tsconfig.build.json文件中

添加"；包括"：["./src"]

看起来像这个

tsconfig.build.json

{
"extends": "./tsconfig.json",
"exclude": ["node_modules", "test", "dist", "**/*spec.ts"],
"include": ["./src"]
}

Answer 5

我不知道是哪个依赖关系导致了我的问题。但对我来说，它只是在我跑步后起作用：

npm audit fix
