I installed the webpack with the command npm install webpack -g , but when I try to use the webpack -h or any other of that problem

After yes, the following error appears

With this error I am useless to use the commands webpack , Someone could help me solve ?

Here is the package.json

{
  "name": "trabalhofinal",
  "version": "1.0.0",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },

    "express": "^4.16.3",

  },
  "devDependencies": {
    "webpack": "^4.6.0",
    "webpack-cli": "^2.1.2",
    "webpack-dev-server": "^2.7.1"
  },
  "description": ""
}

After setting the webpack command the following error appeared when trying to make a Bundle.js

WARNING in configuration
The 'mode' option has not been set, webpack will fallback to 'production' for this value. Set 'mode' option to 'development' or 'production' to enable defaults for each environment.
You can also set it to 'none' to disable any default behavior. Learn more: https://webpack.js.org/concepts/mode/

    Well, as far as I can tell, he’s been installed. Edith your question and place the contents of the file package json. .. If I am not mistaken, to install a global package, use the command npm install -g pacote and not npm install pacote -g That could be where the problem is

  • I edited and put the friend Packge.json !

    Try to remove it: npm uninstall -g webpack-cli and install again: npm install -g webpack-cli

  • Friend worked , however appeared another problem already edited the question and put it, you could take a look ?

  • You should open another question, because it is another project, because you would notice by the directory C: Working Desktop Users

  • Thanks for the help Noobsaibot, thank you very much, it’s all working !

Error may have been caused due to argument order -g in command, which according to the documentation is:

npm install -g webpack-cli

other than the Yarn that is:

yarn add webpack-cli -g
