我正在尝试在Docker容器中运行Typescript express.js。运行docker之后，出现以下错误:
> 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",

},

"@types/node": "^13.13.5",

"typescript": "^3.8.3"
}
}
P.S.我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"
最佳答案
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软件包以包括该补丁。
