Docker doesn't find semantic-ui-react - reactjs

Question

I am new to docker and I want to build a react app (with typescript) inside docker and I need to use semantic-ui-react for that.
I followed the instruction from here to build by app : https://mherman.org/blog/dockerizing-a-react-app/
I added semantic ui usingnpm i -g semantic-ui-react and this is my 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;
When I open http://localhost:3001 I get this error :
./src/App.tsx
Module not found: Can't resolve 'semantic-ui-react' in '/app/src'
I tried to build the docker image using npm then I changed to yarn thinking it will fix.
Build commands i've used so far:
docker-compose build --no-cache && docker-compose up -d --force-recreate
docker-compose build --no-cache
docker-compose up -d --force-recreate --build
my 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
I'm using Ubuntu 18.04
Inside my Dockerfile I've added cat package.json to see if semantic ui is added and it is.
Step 5/7 : RUN cat package.json

]
}
}
I've executed yarn start from terminal and there is no error and the project works fine when I open it in browser.
Why doesn't docker find the semantic ui module ?

Answer 1

Apparently this is a duplicate of Docker-compose: node_modules not present in a volume after npm install succeeds
And the answer from FrederikNS applies here as well. I removed
- '/app/node_modules' from volumes inside docker-compose.yml and now it recognize all modules
