[TypeScript 5.7] Parsing error: Invalid value for lib provided: es2024.promise

[yoursunny]

When XO is installed alongside TypeScript 5.7 and tsconfig.json .compilerOptions.lib includes "ESNext.Promise", the XO CLI reports a parsing error.

package.json

{
  "private": true,
  "type": "module",
  "packageManager": "[email protected]+sha512.c8180b3fbe4e4bca02c94234717896b5529740a6cbadf19fa78254270403ea2f27d4e1d46a08a0f56c89b63dc8ebfd3ee53326da720273794e6200fcf0d184ab",
  "dependencies": {
    "typescript": "~5.7.2",
    "xo": "^0.59.3"
  }
}

  },
  "include": [
    "main.ts"
  ],
  "exclude": [
    "**/node_modules"
  ]
}

console.log(typeof Promise.withResolvers);

Fixed by xo 0.60.0

XO ships with its own typescript version and es2024.promises is v5.7.0+

[yoursunny]

Tested again with xo 0.60.0.
The problem persists.

What's the output of npm ls typescript? XO uses the latest TypeScript version now

[yoursunny]

What's the output of npm ls typescript?

ubuntu@ndndev:~/eslint-bug$ corepack pnpm ls typescript
Legend: production dependency, optional only, dev only

It seems that XO's deps are out of date. The parser is already at 8.18

Defining an override in the package.json helps (at least, the current XO seems compatible with the version bumps):

  "overrides": {
    "xo": {
      "@typescript-eslint/parser": "^8",
      "typescript": "^5.8.1-rc"
    }
  }
