Can't webpack

[kabo]

Here's what I've done

git clone https://github.com/chenglou/reason-react-example.git
cd reason-react-example
yarn install
yarn start
# in another tab
yarn webpack

The webpack command returns

$ webpack -w
/home/kabo/Documents/reason-react-example/node_modules/webpack-cli/bin/config-yargs.js:89

Seems like a webpack-cli bug I thought to myself.

yarn upgrade-interactive --latest # upgraded webpack-cli to 3.1.2
yarn webpack

This time the webpack command returns

$ webpack -w

webpack is watching the files…

and the output continues like that for a good deal longer.

Any ideas?

Interesting, I tried it with npm instead of yarn, and that seems to work...

[rrousselGit]

I used npm, and got that error.

Most likely a breaking change somewhere

Downgrade the webpack-cli version for a quick fix yarn add webpack-cli@2.0.10

[chenglou]

Damn it webpack... Thanks, fixed.
