Zeit `now` deploys fail after version 0.7.0.
See original GitHub issueI’m not sure if this is related to now
, but since upgrading react-scripts
to anything above 0.7.0, my build is now failing on the now deployment.
Here are the logs:
> ▲ npm run build

These are as good of logs I can get right now unless there’s a more verbose logging in react-scripts build.
This may be a Zeit now issue, but the fact that it worked prior to 0.8.x makes me want to bring it up here.
Environment
npm ls react-scripts
(if you haven’t ejected):react-scripts@0.8.1
node -v
:v7.1.0
orv7.0.0
npm -v
:3.10.9
yarn --version
:0.17.4
now --version
:𝚫 now 0.35.0
package.json
: (note “list” and “now-start”)
{
"name": "example",
"version": "0.1.0",
"private": true,
"devDependencies": {
"react-scripts": "0.8.1"
},
"dependencies": {
"list": "^0.9.0",
"react": "^15.4.1",
"react-dom": "^15.4.1"
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject",
"now-start": "list ./build --single"
}
}
How to reproduce
$ create-react-app example
$ yarn add list
$ ... add "now-start": "list ./build --single" to scripts
$ cd example
$ now
Now to make it actually work
$ yarn upgrade react-scripts@0.7.0
$ now

Apologies for the delay with the fix, the underlying issue in
now
has been fixed andreact-create-app
s seems to be building properly innow
Demo/poc app here: https://react-create-app-demo-zqahqhmybz.now.sh/ and src here: https://react-create-app-demo-zqahqhmybz.now.sh/_src/?f=package.json
Just started to get this issue, however I do not use now.sh. Both yarn build/start and npm run build/start produce the same error. Downgrading to 0.7.0 fixes the issue. I tried 0.8.0, and that gave me the same error. Only thing I did between a working build and a non-working build was to add css-loader and style-loader to my dev-dependencies for my server code, which I have since removed, but the error remains.
Tried all the normal stuff, deleted node_modules and the yarn cache. Unsure of what to try next.
EDIT: just tried downgrading to webpack 1 for my server code. Was then able to upgrade back to latest react-scripts and everything worked. Then went ahead and upgraded to latest webpack 2, and everything still works. So… ¯\_(ツ)_/¯
