The most recent version of ScraperWiki depends on Poppler (or so the GitHub says). Unfortunately, it only specifies how to get it on macOS and Linux, not Windows.

You should consider using Windows Subsystem for Linux (WSL).
In the Ubuntu Command-line, run the following commands:
sudo apt-get updatesudo apt-get upgradesudo apt install poppler-utilspdftocairo -v - to check the installed versionYou can then run pdftocairo (for example) in two ways:
pdftocairo ...wsl pdftocairo...NOTE: There is a default version of poppler for each release of Ubuntu. You will need to look up the instructions (there should be plenty on the internet), for how to install the latest version of poppler-utils on Ubuntu. This might involve quite a few steps, which will compile from the source code. For example, something like this https://askubuntu.com/a/722955. And then you might get a lot of problems.
The latest version of Ubuntu 19.04, can install Poppler 74. But Ubuntu 18.04 seems to be the latest version you can install for WSL for now, and that installs Poppler 62.
