@evilebottnawi, sorry about this question. Have you merged? With the webpack-cli version ":" ^ 4.1.0 ", I always have the problem. Thanks so much for all your work.

[alexander-akait]

@gianlucalarizza No problems with 4.1.0

[gianlucalarizza]

@evilebottnawi
thanks for the reply but i still have the same problem.

The only place I have the --watch is in the package.json and not in the webpack configuration options
For example: "npm --progress --watch --config webpack.development.js",

[alexander-akait]

Because npm is not our binary

[gianlucalarizza]

@evilebottnawi
sorry for the lack of knowledge and the different questions. What would your binary be? I can try to understand if I can change. thankssss

webpack --progress --watch --config webpack.development.js

[gianlucalarizza]

@evilebottnawi
In console:

npm run watch

webpack --progress --watch --config webpack.development.js

(node:16064) [DEP_WEBPACK_WATCH_WITHOUT_CALLBACK] DeprecationWarning: A 'callback' argument need to be provided to the 'webpack(options, callback)' function when the 'watch' option is set. There is no way to handle the 'watch' option without a callback.

[alexander-akait]

@gianlucalarizza remove watch: true from your config, you don't need this because you already run --watch

[gianlucalarizza]

@evilebottnawi :) in my package json i have

"scripts": {
"watch": "webpack --progress --config webpack.development.js",
"build": "webpack --progress --mode production --config webpack.production.js",

If in my command line I try to remove --watch, it's works fine but i don't have [webpack-cli] watching files for updates...

Consider that in the webpack configuration file I have not put the watch option

[alexander-akait]

You need to remove watch: true in the config file, please read docs
