Development build fails after upgrading to react-scripts 0.8.2

[AlmeroSteyn]

Description

After upgrading to the latest version of create-react-app and react-scripts (0.8.2) the build task fails.

Expected behavior

Build should pass on a newly created app, or updating an existing app to react-scripts v0.8.2

Actual behavior

In both a newly created app or in an existing app upgraded, the build fails:

Downgrading both scenarios back to v0.8.1 makes the build complete successfully again.

Environment

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

1. npm ls react-scripts (if you haven’t ejected): react-scripts:@0.8.2
2. node -v: v6.7.0
3. npm -v:3.10.8

However I am using Yarn v0.17.10 for all actions.

Then, specify:

1. Operating system: Windows 8
2. Browser and version: Fails in command console, so not applicable

Reproducible Demo

To reproduce create a new app and run yarn build.

Exactly the same here on Windows 7 x64 using npm. Rolling back to 0.8.1 for now.

Thanks for reporting.

I sent a fix in waysact/webpack-subresource-integrity#23, will see how fast it gets merged.

If it doesn't get merged today I'll have to revert the addition of https://github.com/waysact/webpack-subresource-integrity until it's more stable.

cc @jscheid — could you help getting it in asap please?

In the meantime you can fix this locally by applying this change inside node_modules/webpack-subresource-integrity/index.js or (if it doesn't exist) node_modules/react-scripts/node_modules/webpack-subresource-integrity/index.js. The line numbers are slightly different because we use a previous version but you just need to find SubresourceIntegrityPlugin.prototype.hwpAssetPath in the file and replace its contents.

@gaearon Thank you for the fix!

[gaearon]

Sorry about that. We need to start doing Windows CI builds..

This should be fixed in 0.8.3 which was just released.
Please verify.

0.8.3 works for me. Thank you for the super fast fix!

[gaearon]

Please keep up with reports if anything is broken!

[AlmeroSteyn]

Will do!

It works but, when i put the files on server (shared or in Heroku) and access in my mobile phone this error appears:

Failed to find a valid digest in the 'integrity' attribute for resource 'http://facilbardelivery.com.br/static/css/main.33fa5f7d.css' with computed SHA-256 integrity 'fhBe+EZQ6zPH/PQFiIlVZjwvoWQGAWe1s8BEyp2TJ6k='. The resource has been blocked.

Does this help?
Are you modifying files before deployment somehow?
