Add webpack command as an npm script in your package json          name    react-app        version    1 0 0        scripts            compile    webpack --config webpack config js            Then run     npm run compile   When the webpack is installed it creates a binary in   node modules  bin folder  npm scripts also looks for executable created in this folder

We also experienced this problem and I like all the answers that suggest using a script defined in package json    For our solutions we often use the following sequence    npm install --save-dev webpack-cli  if you re using webpack v4 or later  otherwise use npm install --save-dev webpack  see webpack installation  retrieved 19 Jan 2019  npx webpack   Step 1 is a one-off  Step 2 also checks   node modules  bin  You can add the second step as a npm script to package json as well  for example                scripts                      build    npx webpack --mode development                              and then use npm run build to execute this script   Tested this solution with npm version 6 5 0  webpack version 4 28 4 and webpack-cli version 3 2 1 on Windows 10  executing all commands inside of a PowerShell window  My nodejs version is was 10 14 2  I also tested this on Ubuntu Linux version 18 04   I d advise against installing webpack globally  in particular if you are working with a lot of different projects each of which may require a different version of webpack  Installing webpack globally locks you down to a particular version across all projects on the same machine

npx webpack   It is worked for me  I m using Windows 10 and I installed webpack locally

User · Answer

As an alternative  if you have Webpack installed locally  you can explicitly specify where Command Prompt should look to find it  like so   node modules  bin webpack    This does assume that you re inside the directory with your package json and that you ve already run npm install webpack

Install WebPack globally  npm install --global webpack

User · Answer

If you create a boilerplate folder for your JS projects so that you can use JS Modules  webpack and Babel are great tools     Don t install webpack globally and after installing the most recent versions of both  your package json file will be loaded up and ready to copy for future projects   Make sure to delete the node modules folder to decrease file size in your boilerplate folder and then to reinstall node modules use npm install   I forgot to run npm install and kept getting this error when trying to run my webpack dev-server until I realized I needed to run npm install to install node modules and then it worked

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

Maybe a clean install will fix the problem  This  command  removes all previous modules and re-installs them  perhaps while the webpack module is incompletely downloaded and installed   npm clean-install

Webpack CLI is now in a separate package and must be installed globally in order to use the  webpack  command   npm install -g webpack-cli   EDIT  Much has changed  Webpack folks do not recommend installing the CLI globally  or separately for that matter   This issue should be fixed now but the proper install command is    npm  install  --save-dev  webpack   This answer was originally intended as a  work-around  for the OPs problem
