Don't use ancient OS. Just upgrade to Windows 10.

@shinnn Hah-hah. You really think it's my choice? This is a requirement mandated by the client. No issues with other packages, just the gifsicle. Maybe that issue should be filed there instead?

[shinnn]

I just updated the Windows Gifsicle binaries to the latest version. https://github.com/imagemin/gifsicle-bin/commit/921dfab862d970fff5f23c991404f8833386061e

@demisx Can you try npm install imagemin-gifsicle again ? If the spawn UNKNOWN error still occurs, this is not what we can fix and, as you said, should be reported on https://github.com/kohler/gifsicle/issues instead.

[demisx]

Thank you. I ran the install five times and it failed 3 times out of those 5 with the spawn UKNOWN error. I've also received the same error for jpegtran-bin package, so this is clearly not an issue with imagemin-gifsicle, but rather the node/Windows environment. Strange that this error only happens trying to install the image processing packages and not the others. Anyways, thank you @shinnn for giving it a try. Now back to my Mac. 😄

[shinnn]

Now back to my Mac. 😄

Hope your client allows you to modernize the environment 🙏
