Docker ENOENT error on alpine

See original GitHub issue

Hi, I am trying with this dockerfile:

FROM mhart/alpine-node:11.2.0

RUN npm -g config set user root
ENV NODE_PATH=/usr/lib/node_modules

RUN npm install -g html-pdf
RUN npm list -g --depth 0

WORKDIR /usr/src/app
COPY package.json package-lock.json ./

ENV NODE_ENV=production
RUN npm install --only=production
RUN npm audit fix

COPY . .
EXPOSE 8080
CMD ["node", "index.js"]

It installs everything correctly but when I try to use html-pdf I am still getting this error:

{
  Error: spawn /node_modules/phantomjs-prebuilt/lib/phantom/bin/phantomjs ENOENT
  at Process.ChildProcess._handle.onexit(internal/child_process.js: 246: 19)
  at onErrorNT(internal /child_process.js: 421: 16)
  at process.internalTickCallback(internal/process/next_tick.js: 72: 19)
  errno: 'ENOENT',
  code: 'ENOENT',
  syscall: 'spawn /node_modules/phantomjs-prebuilt/lib/phantom/bin/phantomjs',
  path: '/node_modules/phantomjs-prebuilt/lib/phantom/bin/phantomjs',
  spawnargs: ['/node_modules/html-pdf/lib/scripts/pdf_a4_portrait.js']
}

I am not setting any phantomPath to html-pdf create options.

I am trying this on https://zeit.co/

RUN npm list -g --depth 0 is returning an empty list

If this problem is unsolvable I could use another image! I have a working container using node:8.11.1 but it is a 800Mb image and I need something smaller. What would you use?
