Using mozjpeg to compress pictures will result in errors!

• Node Version: 11.15.0
• Imagemin Version: 7.0.1
• Gulp-Imagemin Version: 7.0.0 Imagemin 7.0.0 ^ compress JPEG pictures with mozjpeg。 When I use mozjpeg to compress JPEG images, the tool throws an exception. But pictures in other formats are normally compressed.

import imagemin from 'gulp-imagemin';
const ImageTask = () => {
    return src(['src/images/*.{png,jpg,jpeg,svg,gif}'])
            .pipe(imagemin(
                [
                    imagemin.gifsicle({
                        interlaced: true,
                        optimizationLevel: 3,
                    }),
                    imagemin.mozjpeg({
                        quality: 75,
                        progressive: true
                    }),
                    imagemin.optipng({ optimizationLevel: 5}),
                    imagemin.svgo(),
                ], {
                    silent: false
                }
            ))
            .pipe(dest('dist/images'))
}

The details of the error are as follows

I try to use mozjpeg command directly，like this

npx mozjpeg --help

Exception will still be thrown.

spawn /Users/cuijianwei/WebstormProjects/testproject/gulp-demo/node_modules/mozjpeg/vendor/cjpeg ENOENT

When I reduce imagemin to 6.2.0，Imagemin 6.2.0 compress JPEG pictures with jpegtran, and there’s no problem with jpegtran.

I hope this problem can be solved.

In my case, the problem occurred after I upgrade npm to latest version(7.10.0). At first, I run rm -rf node_modules && npm install but it does’t work at all…

Then I try to check the mozjpeg folder and I found there was no vender/cjpeg. So I try to install packages whith yarn install and at last it works

This seems to be an error with npm >= 7, we were able to get past this with npm install -g npm@6 although really not sure why
