TypeError: PDF2Pic is not a constructor

Hi everyone, I’m trying to use pdf2pic as the example :

let PDF2Pic = require('pdf2pic').default
let converter = new PDF2Pic({
  density: 100,           // output pixels per inch
  savename: "untitled",   // output file name
  savedir: "./images",    // output file location
  format: "png",          // output file format
  size: 600               // output size in pixels
})

// by default the first page of the pdf will be converted
// to image
converter.convert("/path/to/pdf/sample.pdf")
  .then(resolve => {
    console.log("image converted successfully")
  })

But it returns the following error :

/mnt/c/Users/totorelmatador/Desktop/test/test.js:3
let converter = new PDF2Pic({
                ^

    at Function.Module.runMain (module.js:693:10)
    at startup (bootstrap_node.js:188:16)
    at bootstrap_node.js:609:3

I do not understand what is the source of the problem… I tried to remove the .defaut from the require as follow :

let PDF2Pic = require('pdf2pic')

But I obtain this error :

Can someone help me ? 😄 Thank you !

Hi everyone, I have updated the read me file to address this concern. As for the path issue in windows, it would be hard for me to troubleshoot that one as I’m currently using linux. Also, it would be helpful if you can post your node version so I can troubleshoot and possibly update it on my free time. Thanks.

@gopeter remove “.default”. It worked for me.
