Cannot generate woff / woff2 font with node v10.1.0

[lpillonel]

I just updated my gulp workflow setup to node v10.1.0 and everything is working except gulp-icofont when generating woff font. If I remove woff from the formats list, it works as expected (the font is generated).

My task is :

gulp.task('icons', function(){
    return gulp.src('./src/icons/*.svg')
        .pipe(iconfont({
            fontName: `fontname`,
            fontHeight: 1000,
            normalize: true,
            formats: ['woff'],
        }))
        .pipe(gulp.dest('./assets/'));
});

it fails with

[14:23:12] gulp-svgicons2svgfont: Font created

events.js:167
      throw er; // Unhandled 'error' event
      ^
Error: Checksum error in glyf
error Command failed with exit code 1.

If I try with woff2

gulp.task('icons', function(){
    return gulp.src('./src/icons/*.svg')
        .pipe(iconfont({
            fontName: `fontname`,
            fontHeight: 1000,
            normalize: true,
            formats: ['woff2'],
        }))
        .pipe(gulp.dest('./assets/'));
});

it fails with

Everything was working as expected with node v9.11.1.

I’m dealing with the same problem. Gulp-iconfont works fine with all font formats but woff.

Hey, I'm having also trouble with node 10.3.0.

First I had this error:

Finished 'font' after 451 ms
gulp-svgicons2svgfont: Font created

/path/to/project/node_modules/ttf2woff2/jssrc/ttf2woff2.js:1

Error: Checksum error in glyf

Then I added "node-sass":"^4.9.0" to my package.json. Like it is mentioned here: https://stackoverflow.com/questions/41773047/gulp-task-error-checksum-error-in-glyf/41796973#41796973
Now I have the same error like above:

@nfroidure I don't see how this can be related to SVGPathData, as neither woff nor ttf are SVG based?

[nfroidure]

@NaridaL this plugins converts SVG files to a SVG font and then to a TTF one to finally convert it to a WOFF One. That said, it may not be linked at all.

[NaridaL]

I've added node 10 to the CI build, and it fails there too, however it's never run properly on my windows environment, and I don't use this package, so I can't really debug this issue.

[NaridaL]

v10.0.0 should fix this. Please close if so.

[geosigno]

Now I get this issue:

[12:08:36] Starting 'buildICON'...
[12:08:37] 'buildICON' errored after 123 ms
[12:08:37] Error: write after end

[NaridaL]

@geosenna I changed some of the stream handling, which might fix this. Try 10.0.1. Otherwise, I can't do anything without more details (Travis build is passing now...).

[Sir-Genius]

My issue was solved. @NaridaL, thank you!

[lpillonel]

It's ok also for me 🥇
Thanks a lot @NaridaL for your work! 🙇

[geosigno]

Thanks a lot @NaridaL, it is working fine now with the 10.0.1.

[schliesser]

Thx for fixing it. For me v10.0.1 fixed the issue.

[AnastasiaD]

@NaridaL, @geosenna, @schliesser hi, how did you change the version to 10.0.1? I have 10.5.0 now and get the same error. I haven't found 10.0.1 in nodejs releases, only 10.0.0.
Thanks!

[NaridaL]

@AnastasiaD version 10.0.1 of gulp-iconfont, not of nodejs itself.

[AnastasiaD]

Thanks @NaridaL
