Update (Apr 2018)

Webpack 4 onwards you are required to install webpack-cli. You may also want to install webpack-dev-middleware if you need to use the options marked with a key on this page.

In this case the command to install is:

npm install --save-dev webpack webpack-cli html-webpack-plugin webpack-dev-server webpack-dev-middleware

As mentioned above, webpack-dev-middleware should be optionally added based on your requirements.

Node requires you to install webpack to your project.

You have 2 options to solve the above:

1. Remove global webpack and install it locally

   npm uninstall -g webpack
   npm install --save-dev html-webpack-plugin webpack webpack-dev-server
   

2. You can link the global webpack pkg to your project's node modules. The downside of this is that your project will be forced to use most updated webpack. This will create a problem only when some updates are not backwards compatible.

   npm i webpack -g; npm link webpack --save-dev
   

You can omit the html-webpack-plugin depending on your requirement.

You can find more info on this github issue page.

I faced a similar issue when updating my Angular app using ncu. Finally solved it by:

• remove the node_modules directory
• remove package-lock.json
• reinstall the packages.

You can run this in PowerShell (make sure you are in the correct working directory):

rm node_modules -r -force
rm package-lock.json
npm cache verify
npm install

Context:

I had this problem with a React application.

I tried to uninstall webpack globally and locally, also deleted the local folder node_modules, reinstalled all local npm modules (with npm install), etc.

Nothing worked, until doing this...

Solution:

1. Remove package-lock.json & node_modules.
2. Don't remove the other files (like: package.json, index.js...)
3. Install all package (npm extracts information for the installation from package.json) with npm install === npm i.
4. Now, run your code and voila! 

I tried for hours almost every thing suggested on different threads on Stack overflow but nothing worked. Eventually (with a lot of luck) I tried this and it worked:

deleted node_modules library (not sure if required)
npm install -g @angular/cli
npm install @angular/cli
npm install

Below worked for me:-

• Removed node_modules
• Deleted package-lock.json
• Run npm install

This happened to me after I configed 'react-bootstrap' in my next js app. try adding this fixed my problem:

yarn add webpack@webpack-4

or if using npm:

npm i webpack@webpack-4

Check webpack.config.js and make sure all dependencies are installed.

I was having the same problem too. It was resolved by installing html-webpack-plugin dependency. It was defined in my webpack.config.js but not installed.

Remove the package-lock.json and try npm install it will resolve the issue.

This is work for me:

1. npm uninstall -g webpack
2. rm node_modules -r -force
3. rm package-lock.json
4. npm install

You have to check webpack modules already install in the node_modules folder or on your machine? if not install it

For me I fixed this error with:

yarn add --save-dev webpack webpack-cli html-webpack-plugin webpack-dev-server webpack-dev-middleware

It happened when I installed using yarn while the project used npm. I removed the node_modules folder then tried again with npm i

rm -rf node_module
npm install

The reason for this is that the project used specific packages versions which are compatible together but using yarn installed the newest versions which may not fully compatible with the current project.

Check which lock file the project uses then use the corresponding package manager.

This will fix your problem:

npm remove webpack -g
npm i webpack --save-dev
