Building project with tsc fails due to error in Ganache typings

See original GitHub issue

I try to build a library that depends on Ganache v7. When I run tsc I get a bunch of errors for the typings generation.

Node version: 16.9.1 (tried also with 12) Ganache version: 7.0.2

Compiler output:

yarn run v1.22.17
$ rimraf dist && tsc
node_modules/ganache/dist/ganache.d.ts:2162:8 - error TS1005: ',' expected.

2162 removed: Buffer,
            ~

node_modules/ganache/dist/ganache.d.ts:2163:17 - error TS1005: ',' expected.

2163 transactionIndex: Buffer,
                     ~

node_modules/ganache/dist/ganache.d.ts:2164:16 - error TS1005: ',' expected.

2164 transactionHash: Buffer,

[...]

node_modules/ganache/dist/ganache.d.ts:12178:28 - error TS1005: ',' expected.

12178 declare type TxType = [type: Buffer];
                                 ~

node_modules/ganache/dist/ganache.d.ts:12180:25 - error TS1110: Type expected.

12180 declare type TxType_2 = `0x${HexChar}` | `0x${HexPair}`;
                              ~~~~~


Found 81 errors.

tsconfig.json:

{
  "compilerOptions": {
    "target": "ES2020",
    "module": "CommonJS",
    "outDir": "./dist",
    "rootDir": "./src",
    "strict": true,
    "noImplicitAny": false,
    "esModuleInterop": true
  },
  "exclude": [
    "node_modules",
    "**/*.test.ts",
    "examples"
  ]
}

Not sure if related to the known issues regarding typings.

This might just be a problem with typescript versions. Are you on an old version?

I only found https://github.com/microsoft/TypeScript/pull/26568 on SO. You basically would set the default types to one that throws an error and overwrite for a specific version the type definition to the correct one. Seems a little hacky 😬
