Gatsby: [v2] gatsby build hangs on WSL Ubuntu

[dustinheestand]

Description

Build hangs on "Building production Javascript and CSS bundles," after "bootstrap finished." This doesn't happen on Gatsby v1, or with gatsby develop.

Steps to reproduce

1. Make a new gatsby site using command: gatsby new tutorial-part-one https://github.com/gatsbyjs/gatsby-starter-hello-world#v2.
2. Run gatsby build.

Expected result

Gatsby should build the production site.

Actual result

Gatsby hangs on "Building production Javascript and CSS bundles." I let it run for 10 minutes and then quit. This occurs on both the gatsby-cli

I couldn't recreate this just now on my mac. Perhaps this is a linux problem? Also npm occasionally just won't install things correctly so weird problems like this can be fixed by deleting node_modules and reinstalling. Can you try that?

[dustinheestand]

I just had a try - didn't work. However I did manage to get gatsby build to work on the beta on a different Ubuntu machine. That machine is running Ubuntu 18.04 but otherwise has the same config.

Is there any way for me to pinpoint this issue better? The --verbose flag doesn't give me any new info.

Node inspector could help https://nodejs.org/en/docs/guides/debugging-getting-started/

Just wanted to chime in and say that the build script hanged on my machine as well, only it happened at the Building static HTML for pages step, after the Building production JavaScript and CSS bundles successfully finished. I am running KDE Neon (based on ubuntu 16.04), node v8.9.4, npm v.6.2.0. Something fishy is going on here...

[azangru]

Uh-oh, now it started working fine again. I swear it consistently hung after a fresh install of 2.0.0-beta.47. I removed node_modules and reinstalled dependencies several times, and it continued to freeze. And then, after one last reinstall, it started working again. Very strange.

~@pieh reported some oddities with WSL and a recent Windows update. Maybe this is the same thing?~

Edit: nevermind, looks like you're seeing this issue on other Linux machines too.

I've just checked the starter on my machine:

Right, got the issue (not sure whether it’s quite the same issue as reported in the original message) reliably reproduce on my machine:

Steps:

1) use gatsby v.2.0.0-beta.42
2) run gatsby build
3) build completes successfully

...

4) update gatsby to v.2.0.0-beta.47
5) run gatsby build (while keeping the public folder generated during the previous run)
6) build completes successfully

...

7) stay on gatsby v.2.0.0-beta.47
8) delete the public folder generated during the previous run
9) run gatsby build
10) build hangs at the stepBuilding static HTML for pages

===

Running ubuntu 16.04, node v8.9.4, npm v.6.2.0.

Anyone found a workaround for this yet? Or insight into which stage is causing the problem?

Updating to the latest windows insider build solved the issue for me.

[KyleAMathews]

👍 closing this. Please open a new issue if there's something we can do to help make using Gatsby smooth on WSL Ubuntu!

[missaci]

Guys, looking for a workaround, I found out that the problem is caused during the uglify process when using wsl (there are some notes at webpack git talking about uglify hanging when parallel: true).

Setting parallel:false in node_modules/gatsby/dist/utils/webpack-utils.js -> plugins.minifyJs solved the issue for me.

Maybe it can be useful =]
