Cannot find module 'cache-loader' error when trying to upgrade to webpack 5

[xaviarnl]

I am trying to upgrade from webpack 4 to webpack 5. Everything seems to have been updated & modified correctly now, except vue-loader. Whenever I try to create a build, I run into a lot of errors, all of the same form:

Module build failed (from ./node_modules/vue-loader/lib/loaders/pitcher.js):
Error: Cannot find module 'cache-loader'

I am using:

• vue 2.7.0
• webpack 5.74.0
• webpack-cli 4.10.0
• vue-loader: 15.9.8
• vue-template-compiler: 2.7.0
• NPM 8.6.0
• Node 16.17.0 (The only globally installed NPM packages are npm and sass.)

What I have tried so far:

• I started the upgrade using vue-loader 15.10.0, but that gave the same errors;
• I have tried it with vue 2.6.x, as some people reported here that this solved the problem when combined with vue-loader 15.9.8;
• I have removed the node_modules directory and tried a clean install. I also tried the same, after deleting the package-lock.json file;
• I tried: "npm install vue-template-compiler@2.7.0 vue-loader@15.9.8 --save-dev --legacy-peer-deps", as some people reported that this solved build problems for them;

Before the webpack upgrade I was using vue 2.7.0 and vue-loader 15.10.0, and it worked without any problems.
