“image-min”在节点 js 的“multer”中不起作用

Question

在 node-js 中，我使用 multer 包上传图片。压缩图像我使用image-min。

var multer = require('multer');
var imagemin = require('image-min');

app.use(multer({
dest : './public/images/profiles/uploads/',
rename : function(fieldname, filename) {
    return (filename.split(" ").join("")) + Date.now();
},
onFileUploadStart : function(file) {
    console.log(file.originalname + ' is starting ...');
},
onFileUploadComplete : function(file) {

    var imagemin = new Imagemin().src(file.path).use(compressionType);
    imagemin.run(function(err, files) {
        if (err) {
            return next(err);
        }
        console.log('Files optimized successfully!');
    });
    console.log(file.fieldname + ' uploaded to  ' + file.path);
    done = true;
}
}));

当我运行我的代码时，它会抛出错误。

var imagemin = new Imagemin().src(file.path).use(compressionType);
ReferenceError: Imagemin 未定义

Answer 1

var imagemin = require('image-min');

应该是：

var Imagemin = require('image-min');
