Incompatible library version: cjpeg

[joepagan]

Hi,

I'm trying to run mozjpeg with gulp, but I get this error:

[00:13:17] Starting 'minify-jpgs'...

events.js:141
      throw er; // Unhandled 'error' event
      ^
Error: dyld: Library not loaded: /usr/local/opt/libpng/lib/libpng16.16.dylib
  Referenced from: /Users/username/Documents/sites/website.com/node_modules/mozjpeg/vendor/cjpeg
  Reason: Incompatible library version: cjpeg requires version 36.0.0 or later, but libpng16.16.dylib provides version 27.0.0

    at Pipe._onclose (net.js:469:12)

It manages to install ok, here is my task in full:

gulp.task("minify-jpgs", function(){
    return gulp.src([
        "./images/tester.jpg",
    ])
    .pipe(imagemin([
        imageminMozjpeg({
            progressive: true,
            quality: 80
        })
    ]))
    .pipe(gulp.dest("./images/mozjpeg"));
});

I am not sure what to do about this, can't find a similar issue anywhere. Do you have any suggestions?

Getting the same error, but not when using Gulp. It turned out that installing libpng via Homebrew corrected it.

brew install libpng

However, I'm not sure why this is happening. Does this package not also include this utility?

$ brew upgrade libpng

resolved this issue for me

[xiaoyaozi1010]

$ brew install libpng
$ brew update libpng
It's resolved, but the resolution is too inferior...

I'm getting this on an EC2 server, brew is not an option and I do have the latest libpng installed.

This is how I solved this issue on EC2, it seems that the proper version of libpng is not installed via yum. Downloading and compiling from source gives me the library I need.

git clone https://github.com/glennrp/libpng
cd libpng
./autogen.sh
./configure
make
make install
cd /usr/lib64/
ln -s /usr/local/lib/libpng16.so.16
ln -s /usr/local/lib/libpng16.so

Upgrading to version 7 or higher of this library resolves the issue for me.
