Build doesn't work on an Ubuntu server

[vidarc]

If you are reporting a bug, please fill in below. Otherwise feel free to remove this template entirely.

Can you reproduce the problem with latest npm?

Many errors, especially related to "missing modules", are due to npm bugs.

If you're using Windows, follow these instructions to update npm.

If you're using OS X or Linux, run this to update npm:

npm install -g npm@latest

cd your_project_directory
rm -rf node_modules
npm install

Then try to reproduce the issue again.

Can you still reproduce it?

Yes. I have tried installing and re-installing multiple times, using both npm and yarn to install the modules and to run the scripts.

Description

What are you reporting?

The build script runs, but it stops at some point. The build folder gets created and the favicon gets moved over to it, but nothing else appears to happen. The process takes about 13-15secs, while running build on my Macbook correctly builds and takes about 70secs.

Doing either yarn start or npm start works for the dev server.

Expected behavior

Tell us what you think should happen.

Actual behavior

Tell us what actually happens.

Environment

Run these commands in the project folder and fill in their results:

1. npm ls react-scripts (if you haven’t ejected): [email protected]
2. node -v: v.7.2.0
3. npm -v: 4.0.2

Then, specify:

1. Operating system: Ubuntu 16.04
2. Browser and version:

Reproducible Demo

Please take the time to create a new app that reproduces the issue.

Alternatively, you could copy your app that experiences the problem and start removing things until you’re left with the minimal reproducible demo.

(Accidentally, you might get to the root of your problem during that process.)

I've seen reports about this which were resolved when the server was allocated more RAM. Can you check if this helps?

[godmar]

If @gaearon 's suspicion is correct, then your build would have been killed by the OOM killer. You can verify this by looking into the kernel log via dmesg, as described in this SO post.
dmesg -T | tail -30 usually works.
If you see a message 'killed process' with 'node' in it, you know that's the reason.

This occurs when the OS optimistically overcommits virtual memory. It's particularly common in cloud environments that use SSD (and thus have no swap space configured).

[vidarc]

Yep, that was the issue. 512 of RAM couldn't handle it. I added a swap file and it all works well now.

Coming back to this issue 2 years later, glad to see PR #2060 accepted and finding actionable information in the docs. Crosslink to issue #1082 for future googlers.

Also, don't forget the 'dmesg -T' can confirm whether the OOM killer did it or not.
