That's a headscratcher. Do you have libvips installed? |

Yes, running macOS 10.14 Mojave: brew info vips
vips: stable 8.10.5 (bottled)

Something's going wrong with vips loading the image file... Here's the code that's failing: def image
@image ||= Vips::Image.new_from_file(name)
endIt's returning nil when it should be returning an image, which is what's breaking things. We're already making sure the file exists, so I can't think of why that would be happening. Is there some unique configuration here? Can you try it on a brand new jekyll site? |

Works for me, which says it has to do with the environment. I don't have a mac to test on, but I'll look into setting up a vm or a docker container or something. With version 2 we switched from an imagemagick backend to a libvips backend, which brought a lot of performance gain but also seems to cause a lot of issues like this one. It's looking more and more like I'll have to add the imagemagick version back and make it an option to switch between the two. ~/development/tmp

Until we can work out a better solution, might I suggest a docker container? Something like the following: FROM jekyll/jekyll:4
RUN apk add vips imagemagick
WORKDIR /tmp
ENV BUNDLER_VERSION 2.2.12
ENV NOKOGIRI_USE_SYSTEM_LIBRARIES 1
ADD ./Gemfile /tmp/
ADD ./Gemfile.lock /tmp/
RUN gem install bundler -i /usr/gem -v 2.2.12
RUN bundle install
COPY . ./
CMD ["jekyll", "build"]

I was actually trying to do the same thing with an official Ruby image and indeed, it doesn't raise an error. Weird. I will try to see what versions and dependencies of libvips are used in both and compare, maybe that will say something.. |
|
Let me know what you figure out. I'm sorry to say I'm not really smart on package management and the like, but if this is an issue that affects all mac users then I definitely want a better solution than 'use docker'. |
|
FYI, I switched back to 1.14.0 and without libvips, it does work. |
|
Glad to hear that. I've pushed some updates, can you try with 2.0.2? At the very least, the error message should be less useless. |
|
No changes with 2.0.2. The error message remains identical |
|
Damn, ok. Are you using the apple-shipped system version of ruby? Per this discussion I've been having with the ruby-vips maintainer, the homebrew version might be necessary. |
|
Yeah, I installed Ruby 2.6 through Homebrew. I really think this error is out of your scope: with only require "vips"
=> true
irb(main):002:0> img = Vips::Image.new_from_file("apple-touch-icon.png")
=> nil |

Hi, libvips maintainer here, could you perhaps be running an older libvips? I pushed 8.10.6 to homebrew a couple of days ago and it ought to improve PNG loading. I see: Background: we've just switched PNG load libraries. The new load library should be better, but it can be stricter about refusing to load out of spec PNGs. libvips 8.10.6 has tweaks to try to make it a bit more lenient. The next libspng version (due next week) ought to be more generous still. |

@jcupitt I already have 8.10.6 installed. When reinstalling it, I got this message from Homebrew though:

Hello,
I'm trying to use this plugin to first, add width and height attributes to my post images automatically, and secondly to generate responsive images.
Unfortunately, I struggle to make it work: even when I use the picture tag alone, without any preset, I'm getting this error:

The image appears and no error is raised when using
