webpack is not recognized as a internal or external command,operable program or batch file

Answer 1

Sometimes npm install -g webpack does not save properly. Better to use npm install webpack --save . It worked for me.

Answer 2

I had this issue for a long time too. (webpack installed globally etc. but still not recognized) It turned out that I haven't specified enviroment variable for npm (where is file webpack.cmd sitting) So I add to my Path variable

%USERPROFILE%\AppData\Roaming\npm\

If you are using Powershell, you can type the following command to effectively add to your path :

[Environment]::SetEnvironmentVariable("Path", "$env:Path;%USERPROFILE%\AppData\Roaming\npm\", "User")

IMPORTANT : Don't forget to close and re-open your powershell window in order to apply this.

Hope it helps.

Answer 3

you have to install webpack and webpack-cli in the same scope.

npm i -g webpack webpack-cli

or,

npm i webpack webpack-cli

if you install it locally you need to call it specifially

node_modules/.bin/webpack -v

Answer 4

For me it worked to install webpack separately. So simply:

$npm install
$npm install webpack

I'm not sure why this should be necessary, but it worked.

Answer 5

Better solution to this problem is to install Webpack globally.

This always works and it worked for me. Try below command.

npm install -g webpack

Answer 6

The fix for me was locally installing webpack as devDependency. Although I have it as devDependencies it was not installed in node_modules folder. So I ran npm install --only=dev
