Module build failed (from ./node_modules/mini-css-extract-plugin/dist/loader.js):

We are migrating CSS-loader from v0.28.11 to v3.1.0

We have 2 projects:

Project A- No component dependency on any other project - (containing some components)
Project B - We are importing Project A as node modules

We are able to run and build project A successfully. But when we try to run Project B we getting a dependancy error for css files from Project A.

ERROR in ./src/help/css/about.qcss

Same works fine with if we do css-loader of Project A to v3.1.0 and Project B to v1.0.0
But we get a compile-time error if we change both project css-loader version to 3.1.0

We should be able to run and create a build using CSS-loader with version 3.1.0

Solution

This issue happens because of webpack resolve.alias not works

To solve this issue we can use the relative path.

In my case

Currently, I am in Projects\B\src\help\css

and requiring file from node_Modules
/Project/A/src/typography/css/qx-typography.css

so my path be like (**Relative Path**)
../../../../node_modules/Project/A/src/typography/css/qx-typography.css";
