Running into an error when building my site, works fine locally — similar error was found here:

But that solution isn’t possible/working for me, if anyone would help me figure this out I’d really appreciate it.

This could be related to bundler, see:

and

Try removing the ending lines BUNDLED WITH (version number) from your Gemfile.lock before commiting your code again to Netlify.

Hi YJPL,

Thanks for your reply — I’ve tried removing the ‘BUNDLED WITH’ and the solutions in those topics but that doesn’t seem to work, I am using “jekyll_picture_tag” to make responsive images on the site, as mentioned in the initial topic this works fine on my local machine but fails in Netlify:

The origin of those errors can be hard to pinpoint. It looks like some dependencies versions are not agreeing to work with each others.

Your site works locally so that’s good. You could try updating Bundler and Jekyll. I use the same plugin as you do, with Jekyll 4.0.0. My site’s earlier builds show errors similar to yours. Once it was solved by updating a specific npm package, but another step that helped was providing Netlify with a .ruby-version file. Now everything builds fine on the Netlify server but it won’t if Bundler version is specified in Gemfile.lock.

thanks for helping out @YJPL!

@dust-io - if this doesn’t help, let us know, and we’ll take another look.

#6

@YJPL @perry

Updating Bundler didn’t work, I’m just going to attempt the upgrade from Jekyll 3 to 4 and see if that resolves it. The ruby-version file didn’t seem to fix the problem either.

Will update here as soon as I have news, thank-you for your help @YJPL

#7

@perry unfortunately upgrading to jekyll 4 didn’t help either —

if anyone else has any ideas that’d be great, I can’t seem to figure it out.

Edit: Looks like it has something to do with this too: https://github.com/netlify/build-image/issues/157

@dust-io Look, I did another test today and indeed my site gets the same error fails to build after changing Netlify’s Build & deploy settings to Ubuntu Xenial 16.04 (default):

failed with error: convert: delegate failed `"cwebp" -quiet -q %Q "%i" -o "%o"' @ error/delegate.c/InvokeDelegate/1310

The entire site builds fine with Ubuntu Trusty 14.04 (Legacy build image for older sites) selected in Build image selection.

@dust-io @perry Not able to explain why this is, but I hope this is useful.

#9

Hi @YJPL thankyou for pointing this out — the build runs fine on this image, well… apart from the fact it times out now but that’s a different issue. Thanks both for your help.
