运行 webpack 时出现“未找到模块”错误

Question

A few days ago to solve a problem with the webpack module, I had to move my global dependencies to Development dependencies, before everything was working correctly, but now when I run the webpack it returns the following error:

ERROR in (webpack)/lib/node/NodeTargetPlugin.js 
Module not found: Error: Can't resolve 'module' in '.../node_modules/webpack/lib/node'
 @ (webpack)/lib/node/NodeTargetPlugin.js 11:1-18
 @ ./node_modules/worker-loader/dist/index.js
 @ ./node_modules/worker-loader/dist/cjs.js
 @ ./node_modules/pdfjs-dist/webpack.js
 @ ./src/js/index.js
 @ multi ./src/js/index.js

I have already used the methods presented here on StackOverflow and other forums, such as delete the node_modules, yarn.lock folder, clear the cache and as mentioned above install the modules as development dependencies, but nothing worked.

This is my package.json file

I got this same error before and I removed my global webpack, installed locally and run it with web pack, try that

npm remove webpack -g

npm i webpack --save-dev

npm run webpack

If you're running it with local webpack try this: delete packages and install and run.

 npm cache verify

 npm install
