I am not currently working on developing an angular application

Seeking assistance for the issue described below, as I have been struggling with it for three days. Any help would be greatly appreciated.

Despite multiple attempts, the situation only seems to worsen with each try.

The problem arises when attempting to construct an Angular application using ng build --prod. The error message that surfaces is as follows:

ERROR in ./node_modules/ngx-currency/fesm5/ngx-currency.js Module build failed (from ./node_modules/@angular-devkit/build-optimizer/src/build-optimizer/webpack-loader.js): TypeError: Cannot read property 'kind' of undefined at isAngularDecoratorMetadataExpression... [error continues]

Below are my configurations:

tsconfig.json

{
  "compileOnSave": false,
  "angularCompilerOptions": {...}
}

package.json

{
  "name": "angular-ngrx-course",
  "version": "0.0.0",
  "license": "MIT",
  "scripts": {...},
  "private": true,
  "dependencies": {...},
  "devDependencies": {...}
}

Answer №1

When encountering problems in the production build, it's often due to incompatible package versions. Using the most recent package version isn't always the best approach; sometimes downgrading can help resolve these issues.

To pinpoint the problem, check the console for error messages related to a specific function or package. Consider downgrading that package to a more stable release version to address the issue.

Answer №2

I was able to solve the issue by following some not-so-easy steps.

First, I uninstalled and reinstalled node and npm. Then, I tried the solution provided by IAMEVANHE in this URL: https://github.com/nodejs/node-gyp/issues/119#issuecomment-318609877. It didn't work initially, but it seemed like an important prerequisite for the next step. After that, I updated Angular to version 8 and had to address a few minor issues with ViewChild and module imports.

That's all I did. Hopefully, this can assist others facing similar problems.
