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) );

当我使用imagemin得到如下错误时，我是否错过了什么？

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

Answer 1

这是使用imagemin的v4.0.0方式。

安装：npm install imagemin@4.0.0，您的代码将正常工作

imagemin error [TypeError :(输入，输出，opts）=＆gt; {
