node.js - 如何修复用于运行Node.js的: The feature watch recursively is unavailable on the current platform,

Question

我正在尝试在Docker容器中运行Typescript express.js。运行docker之后，我得到以下错误:

> ts-node-dev src/app.ts

Using ts-node version 8.10.1, typescript version 3.9.2
TypeError [ERR_FEATURE_UNAVAILABLE_ON_PLATFORM]: The feature watch recursively is unavailable on the current platform, which is being used to run Node.js
    at Object.watch (fs.js:1441:11)
    at add (/app/node_modules/filewatcher/index.js:74:34)
    at /app/node_modules/filewatcher/index.js:93:5
    at FSReqCallback.oncomplete (fs.js:176:5)

我的Dockerfile:

FROM node:alpine

WORKDIR /app
COPY package.json .
RUN npm install
COPY . .

CMD ["npm","start"]

和package.json文件:

{
  "name": "app-name",
  "version": "1.0.0",
  "description": "Init master",
  "main": "src/app.ts",
  "scripts": {
    "build": "./node_modules/.bin/tsc",
    "start": "ts-node-dev src/app.ts"
  },
  "repository": {

    "@types/node": "^13.13.5",
    "ts-node-dev": "^1.0.0-pre.44",
    "typescript": "^3.8.3"
  }
}

P.S.我已决定包括此修复程序:
更改Dockerfile:

FROM node:lts-alpine

并更改package.json:

"start": "ts-node-dev src/app.ts --poll"

节点v14对fs.watch() API进行了重大更改，特别是recursive选项(Linux从未支持过)now raises the ERR_FEATURE_UNAVAILABLE_ON_PLATFORM error if used on Linux。

一个错误报告和修复已提交给filewatcher:https://github.com/fgnass/filewatcher/pull/6

在合并该修补程序并发布新版本之前，您需要坚持使用NodeJS filewatcher软件包以包含该补丁。
