imagemin Fehler [TypeError: (Eingabe, Ausgabe, opts) => {

Question

function minBytes(originalFilePath, destinationFilePath) { 
    return new Promise(function (resolve, reject){ 
    var Imagemin = require('imagemin'); 

    console.log(originalFilePath) // /app/public/images/temporary/4du_QIGCJb5.jpeg 
    console.log(destinationFilePath) // /app/public/images/database/9d605a80a2cf926513b7fb/4du_QIGCJb5-0.jpeg 

    var imagemin = new Imagemin() 
     .src(originalFilePath) 
     .dest(destinationFilePath); 
    imagemin.run(function (error, files) { 
     if (error != null) { 
     console.log(error) 
     reject(error); 
     } else { 
     console.log(files); 
     resolve(destinationFilePath); 
     } 
    }); 
    }); 
}; 

var minBytesResult = yield Promise.resolve(minBytes(originalFilePath, destinationFilePath)); 

Wenn ich imagemin benutze Fehler wie unten, habe ich etwas verpassen?

[TypeError: (input, output, opts) => { 
    if (!Array.isArray(input)) { 
    return Promise.reject(new TypeError('Expected an arr...<omitted>... 
    } is not a constructor] 

Answer 1
