imagemin 7.0.0 does not generate output png on docker alpine

[ralphkocher]

after upgrading from 6.1.0 to 7.0.0 (both with plugins: imagemin-jpegtran 6.0.0, imagemin-pngquant 8.0.0) imagemin no longer creates an output file for png compression with the following command:

await imagemin(['input.png'], '/output/path', {
  plugins: [
    imageminJpegtran(),
    imageminPngquant({
      quality: [0.6,0.7],
    }),
  ],
});

on docker with latest stable alpine.

after switching back to 6.1.0 it works again as expected.

any ideas? thanks

Wrong call

await imagemin(['input.png'], '/output/path', {
  plugins: [
    imageminJpegtran(),
    imageminPngquant({
      quality: [0.6,0.7],
    }),
  ],
});

await imagemin(['input.png'], {
  destination:  '/output/path',
  plugins: [
    imageminJpegtran(),
    imageminPngquant({
      quality: [0.6,0.7],
    }),
  ],
});

Thanks!

It'd be great if the latest version was running a quick check for the old function signature and threw an error if the second argument is a string. Took me quite some time to fix my code after the version bump.
