markdown-pdf "advanced_shell.md" gives the following error.

internal/validators.js:120
    throw new ERR_INVALID_ARG_TYPE(name, 'string', value);
    ^

TypeError [ERR_INVALID_ARG_TYPE]: The "file" argument must be of type string. Received null

Seemingly related to https://github.com/alanshaw/markdown-pdf/issues/181. Tried the solution there. But which phantomjs gives phantomjs not found.

You can install phantomjs by using sudo npm install -g phantomjs-prebuilt --ignore-scripts however, then the following error occurs when calling markdown-pdf -p $(which phantomjs) mymarkdown.md:

internal/streams/legacy.js:61
      throw er; // Unhandled stream error in pipe.
