Ethers.js: incompatible with latest Typescript compiler

[FSM1]

Having recently upgraded my project to Typescript 3.7.0-beta the project refuses to build throwing the following error:
node_modules/ethers/utils/bytes.d.ts:5:10 - error TS2440: Import declaration conflicts with local declaration of 'Arrayish'.

The error is thrown on the following line of code in utils/bytes.d.ts:

import { Arrayish } from './bytes';
export declare type Arrayish = string | ArrayLike<number>;

Does that mean that TS now has a type named Arrayish? Or are you using npm link for anything, which can also cause this kind of error...

No, I think that it may be a change in how the compiler handles things.

I tried pulling the current ethers.js repo down and upgrading the TS version to 3.7.0-beta and receive the same error.

///////////////////////////////
// Imported Types

import { Arrayish } from './bytes';

///////////////////////////////
// Exported Types

export type Arrayish = string | ArrayLike<number>;

The import {} references itself, and then the type is re-declared in the export. Removing the import statement from utils/bytes.ts resolves the issue.

Tests are all passing.

@ricmoo can I author a merge request?

This is one of the breaking changes in TS 3.7 - thanks for the heads-up @FSM1

Oh! I just looked at that file... Yes, I'm surprised that ever worked... I'll fix that now. :)

[ricmoo]

This has been published to NPM and a release has been cut.

Please try out 4.0.38 and let me know if you still have any problems. :)

Works a charm @ricmoo 💯
