What steps can I take to fix the 'node module error' while deploying a project on Vercel?

While working with the world-countries package, I encountered an issue during deployment in Vercel. The error message indicated that a ';' was missing in the index.d.ts file of world-countries located in the node_module directory.

Here is the exact error from Vercel:

Failed to compile. ./node_modules/world-countries/index.d.ts:45:37 Type error: ';' expected. 43 | translations: { [languageCode: string]: OfficialAndCommon } 44 | latlng: [number, number]

45 | demonyms: { [languageCode: string]?: Demonyms } (this is the line that needs to be fixed) | ^ 46 | landlocked: boolean 47 | borders: string[] 48 | area: number

I attempted deleting the '?' as suggested and the issue resolved within the file itself, but unfortunately, Vercel did not accept these changes. I also tried reverting back to the previous method where demonym was defined as a string. Additionally, I experimented with different ways to bypass the error without success.

Despite my efforts, I have not been able to resolve this issue.

Answer №1

To resolve the issue, removing the ? is necessary. However, Vercel will not accept the modified version from your local environment because it performs an npm install.

It seems that this problem will be addressed in the upcoming release of the world-countries package, as indicated in this PR

You have two choices:

Option 1

Wait for the new version of world-countries and execute 

npm install world-countries@latest

Option 2

Replace the index.d.ts file of world-countries, but how?

Step 1 Create your own index.d.ts file

Step 2 Instruct Typescript to use this custom file rather than the original one

  • Add a new path in your tsconfig.json:
"world-countries": [
    "./types/world-countries/index.d.ts"
 ],

For testing purposes, I suggest deleting the node_modules folder, performing a clean npm install, followed by npm run build.
