DynamicScraper from the example not doing anything

[jeremythille]

I'm trying out the examples exactly as written. The HackerNews example with scraperjs.StaticScraper works perfectly fine and I get a big array of strings.

However, replacing Static with Dynamic doesn't do anything. At all. The execution just ends with no error. I tried debugging it, adding try/catch statements, but I still get no error.
I tried "npm install phantom" too, but it doesn't change anything for scraperjs.
I have no idea what's wrong here.

@jeremythille @abinashmeher999 It will work, if you downgrade phatomjs to 1.9.8 version as mentioned in #53

I downgraded to phantomjs 1.9.8 but it still does not work on Mac OS 10.11.5.

Removing the folder node_modules and install again did the trick for me.

Downgraded to 1.9.8 and no luck

Check your version of node. It looks like DynamicScraper doesn't work with newer node versions. node 7.9 didn't work for me, but 4.8.2 worked fine.

I'm building a docker image to encapsulate the correct version of node/phantom/scraperjs, as it appears there's a pretty specific set of versions that are required to make this all work.

This Dockerfile worked for me:

FROM node:4.8

WORKDIR /scraperjs
RUN npm install scraperjs
RUN npm install -g 'phantomjs@1.9.8'
ENV NODE_PATH=/scraperjs/node_modules

then:

# assumes dynamic HN example is in 'hn.js'
$ sudo docker build -t coopernurse/scraperjs .
$ sudo docker run --rm -v `pwd`:/code coopernurse/scraperjs node /code/hn.js
