Troubleshooting the error message "Encountering issues with Module build failed (from ./node_modules/postcss-loader/src/index.js)"

Running ng serve results in compilation failure after the chunks are generated.

The same codebase is functioning on a co-worker's computer with identical versions as listed below:

  • Node version: 10.16.3
  • NPM version: 6.9.0
  • @angular/cli: 7.3.9

Tried the following troubleshooting steps:

  • Tested with nodejs lts/Dubnium, encountered the same issue.
  • Ran npm i after forcefully clearing the npm cache.
  • Uninstalled both Node and NPM from the system and reinstalled everything.

Command used: ng serve

The error received was:

ERROR in ./src/assets/css/style.css (./node_modules/@angular-devkit/build-angular/src/angular-cli-files/plugins/raw-css-loader.js!./node_modules/postcss-loader/src??embedded!./src/assets/css/style.css)

Answer №1

After troubleshooting, I was able to find the solution. The issue stemmed from an extra comma at the end of the CSS line provided below, causing postcss to generate an error.

background-image: linear-gradient(to right, #973a95, #055faa, );

By removing the unnecessary comma, the problem was fixed and the code worked as intended.

background-image: linear-gradient(to right, #973a95, #055faa);
