Copy-webpack-plugin: TypeError: compilation.getCache is not a function

[Iffyyy]

i install this plugin with npm in my vue project,and configured in vue.config.js.when i start the project,it told me that 'TypeError: compilation.getCache is not a function' at 'copy-webpack-plugin\dist\index.js:459:33'

@Iffyyy I hit this after a fresh install npm i copy-webpack-plugin — that'll install v7 of the plugin, which requires webpack 5. I'm not using webpack 5, and resolved by npm i copy-webpack-plugin@6.

Something stating "v6 of this plugin works with webpack v4" really needs to be added to the README.

Please do not ignore messages from package manager you need webpack@5 for latest version

@AzrizHaziq it means you still on webpack@4, run npm ls webpack

update webpack-cli to the 4 version

I think i mess up a little bit. I'm currently using lerna, and strangely it was using webpack@4.*.
Please ignore my previous comment 😄 .

Thanks @alexander-akait.
