Docker Build cannot download

I’ve seen similiars posts, but none was using docker. I’m having an issue when doing a docker build:

When running the command:

docker build -t frontend -f frontendDockerfile .

I get:

Downloading binary from
Cannot download "": 

HTTP error 404 Not Found

Hint: If is not accessible in your location
      try setting a proxy via HTTP_PROXY, e.g. 

      export HTTP_PROXY=

or configure npm proxy via

      npm config set proxy

Here is my frontendDockerFile:

FROM node

COPY /frontend/Express /Express

WORKDIR /Express

#RUN npm install && npm rebuild node-sass && npm run webpack
RUN npm install  && npm run webpack

CMD ["npm", "start"]


I would be very thankful if someone could help me.
