Docs: `--colors` is not a valid options in webpack 5

https://github.com/rails/webpacker/blame/master/README.md#L214

$ ./bin/webpack --watch --colors --progress
[webpack-cli] Error: Unknown option '--colors'
[webpack-cli] Run 'webpack --help' to see available commands and options

Also, colors seems enabled by default

It may be also worth to note that ./bin/webpack --help does not work anymore

Webpacker v6

$ ./bin/webpack --help
[webpack-cli] Incorrect use of help
[webpack-cli] Please use: 'webpack help [command] [option]' | 'webpack [command] --help'
[webpack-cli] Run 'webpack --help' to see available commands and options

Webpacker v5

$ bin/webpack --help
webpack-cli 3.3.12

Usage: webpack-cli [options]

Nice catch, will dig into that later this week

Ok I did some tests. Colors are enabled by default in Webpack 5, but we can disable them with --no-color and remove --color (note that is singular now) from your command.

The help command changed a lot between Webpack 4 and 5. I opened a PR to allow usage of these commands: #3144
