reactjs - Docker 找不到语义-ui-react

Question

我是 docker 新手，我想在 docker 内构建一个 React 应用程序(带有 typescript)，并且我需要使用语义-ui-react。我按照此处的说明通过应用程序进行构建:https://mherman.org/blog/dockerizing-a-react-app/

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;

当我打开http://localhost:3001时我收到此错误:

./src/App.tsx
Module not found: Can't resolve 'semantic-ui-react' in '/app/src'

我尝试使用 npm 构建 docker 镜像，然后我更改为yarn，认为它会修复。到目前为止我使用过的构建命令:

docker-compose build --no-cache && docker-compose up -d --force-recreate

docker-compose build --no-cache

docker-compose up -d --force-recreate --build

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"]

我的 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

我使用的是 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 ui，确实如此。

Step 5/7 : RUN cat package.json

    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

我已经从终端执行了yarn start，并且没有错误，并且当我在浏览器中打开它时该项目工作正常。

为什么 docker 找不到语义 ui 模块？

Answer 1

显然这是 Docker-compose: node_modules not present in a volume after npm install succeeds 的重复项

FrederikNS 的答案也适用于此。我删除了

- '/app/node_modules' 来自 docker-compose.yml 内的卷，现在它可以识别所有模块
