Export error esm with gulp4

[ghost]

Gulp: To use esm we should

• rename gulpfile.js to gulpfile.esm.js
• npm install esm -D

But running gulp this produces

[17:24:41] Requiring external module esm
/home/sm/blog/gulpfile.esm.js:139
export minify
       ^

SyntaxError: Invalid or unexpected token
    at Object.Module._extensions..js (node:internal/modules/cjs/loader:1121:10)

Any ideas?

That is a wrong export.

Use export {module1, module2}. In this case export {minify}
