Unable to properly invoke markdown-pdf

See original GitHub issue

Hello, just updated and tried to use it again with very simple invocation:

markdown-pdf doc.md

I expected a doc.pdf to be created. Instead I got the following error message:

internal/validators.js:118
    throw new ERR_INVALID_ARG_TYPE(name, 'string', value);
    ^

TypeError [ERR_INVALID_ARG_TYPE]: The "file" argument must be of type string. Received null
    at validateString (internal/validators.js:118:11)
    at normalizeSpawnArguments (child_process.js:406:3)
    at spawn (child_process.js:546:13)
    at Object.execFile (child_process.js:232:17)
    at WriteStream.<anonymous> (/usr/local/lib/node_modules/markdown-pdf/index.js:117:22)
    at WriteStream.emit (events.js:333:22)
    at finishMaybe (_stream_writable.js:697:14)
    at _stream_writable.js:673:7
    at WriteStream._final (internal/fs/streams.js:377:3)
    at callFinal (_stream_writable.js:666:10) {
  code: 'ERR_INVALID_ARG_TYPE'
}

Aside it created an empty doc.pdf file, also indicating that it’s not a permission issue on my system. I am using macOS Catalina.

Cheers, Florian

This answer from #181 worked for me on Ubuntu 18.04:

markdown-pdf -p $(which phantomjs) mymarkdown.md

$ markdown-pdf -c ./ readme.md
