Please make sure you're using TS of at least 2.8
Check your typescript version using

tsc -v

If it's less than 2.8 upgrade it with following command.

npm install -g typescript@latest

Please let me know if this works.

it's typescript compiler problem. just replace 'let' with 'var' then error disappear. but it is not a proper solution.

I needed to update my d3 types dependency. In my package.json I now use:

    "@types/d3": "^7.1.0",

Then npm install. Previously I was using version 5.7.1, which gave that error.
