A project I have been working on recently based on CRA (create-react-app) for TypeScript needed a large jump upgrade (3.1.1 to 3.4.0). Finally after working through a lot of other well documented problems I hit this one:
'=' expected. TS1005
The error occuring in the file jest-diff line 1:
import type { DiffOptions } from './types'
This was strange to me because I had not changed anything related to jest or my testing setup.
Luckily I was able to find this github issue: https://github.com/facebook/jest/issues/9703
The user got it spot on- I upgraded to TypeScript 3.8.3 and was able to compile again.
