I was trying to use newest alpha version of esbuild-loader (3.0.0-alpha.1) and older ones (1.3.1) but with no success. Upgrading node to 10.23.3 is solving this issue, but it would be good to have older nodes support.

Reproduction steps

1. use node version 8.17.0 and npm 6.13.4
2. install dependencies
3. try to build using esbuild-loader

Environment

• esbuild-loader version: 2.9.1
• Operating System: Ubuntu20.10
• Node version: 8.17.0
• Package manager (npm/yarn/pnpm) and version: 6.13.4

Based on your error stack, it seems that the incompatibility is coming from esbuild rather than esbuild-loader.

Node.js 8 LTS has ended but you can give try requesting support at https://github.com/evanw/esbuild
