Recently, I encountered an issue with my React / Mobex application written in TypeScript and built by Webpack 1. Upon updating the TypeScript version from 2.3.4 to 2.4.2, an error started occurring. The error message reads:
ERROR in C:\myproject\tsconfig.json
error TS2688: Cannot find type definition file for 'reflect-metadata'.
Even after trying Typescript 2.7.2 and explicitly providing the path to typings in "paths", as well as installing the latest version of 'reflect-metadata' globally, the error persists.
