Typecheck is failling in your truffle-v5 example

Hello,

I just cloned your example, and:

npm i

npm run typecheck

leads to:

$ npm run typecheck

> example-truffle-v5@0.0.1 typecheck
> tsc --noEmit

types/truffle-contracts/index.d.ts:4:9 - error TS2669: Augmentations for the global scope can only be directly nested in external modules or ambient module declarations.

4 declare global {
          ~~~~~~

types/truffle-contracts/types.d.ts:17:34 - error TS2694: Namespace 'Truffle' has no exported member 'Artifacts'.

17 declare const artifacts: Truffle.Artifacts;
                                    ~~~~~~~~~


Found 2 errors.

Did I miss a step or do something wrong? Thanks in advance.

Problem seems to be the single quotes used in the generate-types script causing typechain to match 0 files which causes various other problems, including the error you’ve seen. Changing the single quotes to double quotes allows it to match the files and the errors go away. I’m assuming this is only a problem for Windows, and that’s why this wasn’t detected in CI.

I am closing this for now as this is windows specific.

I created: https://github.com/ethereum-ts/TypeChain/issues/411 and it’s marked as help wanted :-> If you want to pick it up and add CI config for windows you have all my support. Thanks for reporting.
