Reactjs Docker没有'；找不到语义用户界面

我是docker的新手，我想在docker内部构建一个react应用程序（带有typescript），我需要使用语义ui react。 我按照这里的说明按应用程序构建：

我使用npm I-g semantic ui react添加了语义ui，这是我的App.tsx：

import React from 'react';
import './App.css';
import {Button} from "semantic-ui-react";

class App extends React.PureComponent {

    render() {
        return (<div>
            This is text
            <Button>
                ok
            </Button>
        </div>)
    }
}

export default App;

我试着用npm建立docker的形象，然后我改成了Thread，认为它会解决问题。 到目前为止我使用过的构建命令：

docker compose build—无缓存和&docker compose up-d—强制重新创建

docker compose build--无缓存

docker compose up-d--强制重新创建--构建

我的Dockerfile

# base image
FROM node:12.2.0-alpine

# set working directory
WORKDIR /app

# add `/app/node_modules/.bin` to $PATH
ENV PATH /app/node_modules/.bin:$PATH

# install and cache app dependencies
COPY package.json /app/package.json
RUN cat package.json
RUN yarn install

# start app
CMD ["yarn", "start"]

my docker-compose.yml：

version: '2.2'

volumes:
  frontend:

services:

  frontend:
    container_name: container
    build:
      context: .
      dockerfile: Dockerfile
    volumes:
      - '.:/app'
      - '/app/node_modules'
    ports:
      - '3001:3000'
    environment:
      - NODE_ENV=development

我正在使用Ubuntu 18.04

在我的Dockerfile中，我添加了

cat package.json

，以查看是否添加了语义用户界面，以及它是否正确

Step 5/7 : RUN cat package.json

  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

我已经从终端执行了

warn start

，当我在浏览器中打开它时，没有错误，项目工作正常

为什么docker找不到语义ui模块？

显然这是

弗雷德里克斯的答案也适用于这里。我搬走了

-'/app/node_modules'

来自docker-compose.yml中的卷，现在它可以识别所有模块
