Production Build Randomly Fails

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?

Yes.

Description

The html file build randomly fails, leading to a missing HTML file. This happens silently and intermittently.

Repro instructions:

1. Delete the build/ contents between runs
2. Run build
3. Make sure build/index.html got generated – if build/index.html is missing, you’ve reproduced the bug
4. Repeat

Expected behavior

HTML file should always build.

Actual behavior

Building from scratch, build/index.html intermittently fails to get generated.

Environment

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

1. npm ls react-scripts (if you haven’t ejected): N/A - I have ejected
2. node -v: v6.9.1
3. npm -v: 4.0.2
4. create-react-app --version: 0.6.0

Then, specify:

1. Operating system: Ubuntu 16.04.1 LTS
2. Browser and version: N/A

Reproducible Demo

Run create-react-app with defaults and you’ll have it, but you may have to run build a lot to repro the problem.

We’ll need to figure out which part of the build is so memory hungry.

I’ve seen silent failures in npm run build due to out-of-memory conditions on machines with no swap space. Next time this happens, check your system logs (see my comment in #1133)
