DedupePlugin fails: No template for dependency: TemplateArgumentDependency

Hi folks,

Great job with Webpack, this framework is really helping my project to succeed. I’m using version 1.8.11 through gulp-webpack and after I’ve added react-intl in my project this problem started to happen:

Error: No template for dependency: TemplateArgumentDependency

After some investigation and checking out some suggestions in the webpack Gitter chat, I decided to remove the Dedupe Plugin and then everything works again, but my bundle size has increased significantly.

Any ideas on how to make the DedupePlugin work again? If I get any pointers I could try to solve the issue myself. Any help here is much appreciated.

Thanks!

For anyone encountering this in the future, the comment referenced above says:

Error: No template for dependency: TemplateArgumentDependency happens when you have multiple webpack copies installed and used the DedupePlugin from a different copy.

I was using a serverless-webpack-plugin which had it’s own webpack dependency it was using to bundle files. However, I had manually installed and required webpack in my project’s webpack config as well (like you normally would with webpack). Consequently, when I removed my explicitly installed version of webpack with npm rm --save-dev webpack, the plugin was able to require it’s own scoped webpack dependency instead which worked.

I’ll alert the serverless-webpack-plugin repo to this issue to figure out how to make it easier to use in the future.

rm -rf node_modules && npm i solved the issue. Please ignore my previous message.
