我已从以下位置下载示例 docker 入门项目：getting-started-webpage

{
    "name": "101-app","version": "1.0.0","main": "index.js","license": "MIT","scripts": {
        "prettify": "prettier -l --write \"**/*.js\"","test": "jest","dev": "nodemon src/index.js"
    },"dependencies": {
        "body-parser": "^1.19.0","express": "^4.17.1","mysql": "^2.17.1","sqlite3": "^4.1.0","uuid": "^3.3.3","wait-port": "^0.2.2"
    },"prettier": {

    },"devDependencies": {
        "jest": "^24.9.0","nodemon": "^1.19.2","prettier": "^1.18.2"
    }
}

抛出异常::

at Object.<anonymous> (C:\Users\Ulrich Giorgio Jäger\IdeaProjects\docker-tutorial-app\node_modules\sql
ite3\lib\sqlite3-binding.js:4:15)
error MODULE_NOT_FOUND

Dockerfile：

FROM node:12-alpine
RUN apk add --no-cache python g++ make
WORKDIR /app
COPY . .
RUN yarn install --production
CMD ["node","src/index.js"]

所以我的问题是为什么它在复制到 docker 容器而不是本地时有效

我可以从 settings.json 更新所有依赖项，现在这个错误消失了。 我现在正在为另一个问题而苦恼

有谁知道为什么。经过如此多的更新后，这在我的本地机器上不起作用，即使端口为新连接打开，端口仍被标记为已占用
