title: trouble with multiple parms and RUN
body: <p>I'm trying to get Parcel Bundler to build assets from within a Dockerfile.  But its failing with:</p>
  
  <blockquote>
    <p>  No entries found.
        at Bundler.bundle (/usr/local/lib/node_modules/parcel-bundler/src/Bundler.js:260:17)
        at  ERROR: Service 'webapp' failed to build: The command '/bin/sh -c parcel build index.html' returned a non-zero code:
    1</p>
  </blockquote>
  
  <p>Here's my dockerfile:</p>
  
  <pre><code>FROM node:8 as base
  WORKDIR /usr/src/app
  COPY package*.json ./
  
  # Development
  FROM base as development
  ENV NODE_ENV=development
  RUN npm install
  RUN npm install -g parcel-bundler
  WORKDIR /usr/src/app
  RUN parcel build index.html     &lt;----- this is where its failing!
  #RUN parcel watch index.html
  # Uncomment to use Parcel's dev-server
  #CMD [ "npm", "run", "parcel:dev" ]
  #CMD ["npm", "start"]
  
  # Production
  FROM base as production
  ENV NODE_ENV=production
  COPY . .
  RUN npm install --only=production
  RUN npm install -g parcel-bundler
  RUN npm run parcel:build
  CMD [ "npm", "start" ]
  </code></pre>
  
  <p>NOTE: I'm trying to get this to run in Development mode first.</p>
  
  <p>When I "log into" the container, I found that this command does fail:</p>
  
  <pre><code># /bin/sh -c parcel build index.html
  </code></pre>
  
  <p>But this works:</p>
  
  <pre><code># parcel build index.html 
  </code></pre>
  
  <p>And this works:</p>
  
  <pre><code># /bin/sh -c "parcel build index.html"
  </code></pre>
  
  <p>But using these variations in the Dockerfile still do NOT work:</p>
  
  <pre><code>RUN /bin/sh -c "parcel build index.html"
  </code></pre>
  
  <p>or</p>
  
  <pre><code>RUN ["/bin/sh", "-c", "parcel build index.html"]
  </code></pre>
  
  <p>NOTE: I also tried 'bash' instead of 'sh' and it still didn't work.  </p>
  
  <p>Any ideas why its not working?</p>
