ESM-only ESM-only since 3.0.0 — last CommonJS version is 2.2.0

p-try dropped its CommonJS build in 3.0.0 (October 2021). The last version with a plain require()-able CommonJS entry is 2.2.0, published Mar 31, 2019; it declares support for Node.js >=6.

On Node.js 20.19+, 22.12+ and newer, require("p-try") works with the latest version: Node.js loads synchronous ES modules through require(). Verified on Node.js 20, 22, 24 and 26. On Node.js 18, which has no require(esm), require("p-try") fails with ERR_REQUIRE_ESM.

What to do

  1. On Node.js 20.19+, 22.12+ and newer, require("p-try") works with the latest version: Node.js loads synchronous ES modules through require(). Verified on Node.js 20, 22, 24 and 26.
  2. From a CommonJS file, use a dynamic import inside an async function: const pTry = await import("p-try"). That works on every Node.js version the package supports (^12.20.0 || ^14.13.1 || >=16.0.0).
  3. If you need a synchronous require() or run Node.js 18: npm install p-try@2.2.0, the last CommonJS release (published Mar 31, 2019); it declares Node.js >=6.
  4. TypeScript: npm install -D @types/p-try

How to import p-try

ES modules (import)

import * as pTry from "p-try";

Namespace import shown because the ESM entry may have no default export; use named imports for what it exports.

CommonJS (require)

// Node.js 20.19+, 22.12+ and newer (verified):
const pTry = require("p-try");

// Any Node.js version the package supports (^12.20.0 || ^14.13.1 || >=16.0.0), from an async function:
async function main() {
  const pTry = await import("p-try");
}

// Or pin the last CommonJS release (declares Node.js >=6):
// npm install p-try@2.2.0

Module format by version

Derived from the type, main and exports fields of every stable release on npm, corrected where a runtime test of that version contradicted them (5 versions; the newest 5 shown).
