It seems to have something to do with parameterless catch statements in the newest version of node-fs-extra.
This is a new feature only available in nodejs since 10.3.

My Node version is 12.16.2 and still happens. Any workarounds?

For the workarounds, using hugo binary from github release.

sudo snap remove hugo
mkdir hugobin
cd hugobin
curl -L https://github.com/gohugoio/hugo/releases/download/v0.74.3/hugo_extended_0.74.3_Linux-64bit.tar.gz | tar -xz
sudo mv hugo /usr/local/bin/hugo
cd ..
rm -r hugobin

Hi @jmooring,

Sorry for the late follow-up.

It seems to have something to do with parameterless catch statements in the newest version of node-fs-extra.
This is a new feature only available in nodejs since 10.3.

https://github.com/jprichardson/node-fs-extra/blob/master/lib/mkdirs/make-dir.js#L85

The current Hugo snap bundles a copy of nodejs 8.12.0, so would that be the culprit? I.e., would bundling a newer copy of nodejs in the Hugo snap fix the issue?

[jmooring]

@anthonyfok

would bundling a newer copy of nodejs in the Hugo snap fix the issue?

I have no idea. Why don't you give it a try? See "To Reproduce the Issue" in the original issue comment.

Do we have to bundle nodejs? For a Hugo user to use PostCSS they have to install postcss-cli using npm which which requires nodejs. So they already have nodejs installed.

[anthonyfok]

Do we have to bundle nodejs?

For a confinement: strict snap, I believe so. Hugo-as-a-snap cannot access the nodejs outside of the snap.

Please correct me if I am wrong though as it would make things much easier. ;-)

[anthonyfok]

The fix is committed in commit 748fd4c, though admittedly I am not sure if it would solve your problem yet.

Please either:

• wait a day or two, then install the latest the Hugo snap from the edge channel, or
• wait until the next Hugo release (0.75.0?) when its snap is released to the stable channel.

If the issue isn't really fixed, please re-open this issue and @ me. Thanks!
