P.s.

1. removing node_modules and reinstalling with npm i - didn't help
2. trying to npm i @angular/cli --save-dev - didn't help
3. downgrade to 1.6.8 - helped

Tested on 1.7.1 and still happening :(

Heya, this issue is a duplicate of https://github.com/angular/angular-cli/issues/6417. You can see the answer to it in https://github.com/angular/angular-cli/issues/6417#issuecomment-315708400.

The short version is that you can't have multiple versions of webpack on your node_modules. Removing the extra webpack installs should fix it.

[amcdnl]

This was happening for me because I had storybook installed which comes with its own webpack version.

[GeorgeKnap]

@filipesilva Hi, I've seen your explanation over and over but I haven't been able to build app without explicitly installing webpack in my devDependencies since cli version 1.6 or so. Without webpack I've been getting this error Cannot find module 'webpack/lib/node/NodeTemplatePlugin'. That was always fixed by having webpack in devDependencies.

Now after upgrading to RC 6 versions I'm getting exactly same ContextElementDependency error and removing webpack from devDependencies simply causes the NodeTemplatePlugin error again.

I wonder what's wrong here.

@angular 6.0.0-rc.1
@angular/cli v6.0.0-rc.0
webpack 4.4.1

[davyvanlaere]

I have the exact same issue with the NodeTemplatePlugin error. The only way to fix is is by installing a higher webpack version ...

[AlaaAhmedBM]

Do anyone get a solution to this error?

[yzini-eagle]

@AlaaAhmedBM try this answer just remove the package-lock.json before npm install it worked for me!

[redplane]

I have the same issue. I've search for solutions and uninstall webpack from my project. When I run the command : ng serve, I have another one: Cannot find module webpack.

Its very annoying.

[redplane]

@yzini-eagle , seeing your solution. What I have tried is :

• Remove node_modules.
• Remove package-lock.json.
• npm cache clean --force
• npm install

It worked. However, I don't know what the root cause is.

[adujoseph]

This works just fine for me with angular 6: remove webpack from DevDependencies in Package.json rimraf node_modules/ (remove node_modules folder) rimraf package-lock.json (remove package-lock.json file) npm install -g webpack (install webpack globally) npm install -g webpack-dev-server npm install ng serve or ng build
