=> ERROR [5/5] RUN npm install or yarn in Dockerfile

I am trying to Dockerise a React app, but when it reaches the command to install npm it throws an error.

My Dockerfile contains:

# pull official base image
FROM node:12.6.0-alpine


# set working directory
RUN mkdir /app
COPY . /app
WORKDIR /app
ENV PATH /app/node_modules/.bin:$PATH

RUN yarn

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

The error is this when it reaches the command to run npm install or yarn:

[5/5] RUN yarn:

    the package was not installing due to admin authorization issues so I use force command to install and it worked

    RUN npm install --force
