Error: The script cannot be compiled with the '--isolatedModules' flag as it is recognized as a global script file

Currently, I am working on building my NextJS app and incorporating Cypress for testing along with Typescript. During this process, I encountered the following error:

Type error: 'home.cy.ts' cannot be compiled under '--isolatedModules' because it is considered a global script file. Add an import, export, or an empty 'export {}' statement to make it a module.

Error location: ./cypress/e2e/home.cy.ts:1:1

GitHub link: https://github.com/GSdaBlessedFist/unsplash-inspired/blob/main/cypress/e2e/home.cy.ts

  • I have already included an export in my index.ts file
  • I attempted setting 
    "isolatedModules": false
    , in the tsconfig.json file, but the issue persists.

Answer №1

One troubleshooting step you can try is removing all cypress files from your tsconfig.json and then running the separate 

npx tsc -p cypress/tsconfig.json --noEmit
process to verify the types of your cypress files.
