Issue with typing error in datetime.d.ts file that is missing

I initially installed the typings for luxon using 

npm install --save-dev @types/luxon
. However, upon further evaluation, I realized that it was unnecessary and decided to remove it manually:

  • deleted the folder node_modules/@types/luxon
  • removed entries in package.json
  • erased references to luxon in package-lock.json

Despite these removals, I continue to encounter an error after building in Visual Studio 2022:

Build: Namespace 'Intl' does not have an exported member 'DateTimeFormatPart' with a project path that appears incorrect (C:\dev\...\node_modules@types\luxon\src\datetime.d.ts 1238).

Even attempting to use npm prune did not resolve this issue.

Answer №1

Solving this issue is possible by deleting the node_modules folder (e.g. using rm -r node_modules, or the equivalent on Windows), followed by a fresh installation: npm install.

To avoid encountering similar problems in the future, it's recommended to uninstall packages with npm uninstall, for example npm uninstall @types/luxon. You can also eliminate the package from either dependencies or devDependencies in your package.json and execute npm install.

Answer №2

It turned out the issue lied within my directory setup. My frontend code is located in c:\dev\solutionPath\ProjectPath, where the node_modules folder resides. However, at one point, I mistakenly ran npm install one level up at c:\dev\solutionPath, which resulted in another node_models folder being created.
