Gatsby: TypeError: Cannot read property 'minify' of undefined at minify with terser plugin

Created on 2 Feb 2019 · 7Comments · Source: gatsbyjs/gatsby

Description

Production build doesn't build, but dev build is good

Steps to reproduce

Just run gatsby build

P. S. This is after update
Part of yarn.lock before update while everything's works (good prod build without any errors)

terser@^3.8.1:
  version "3.14.1"
  resolved "https://registry.yarnpkg.com/terser/-/terser-3.14.1.tgz#cc4764014af570bc79c79742358bd46926018a32"
  integrity sha512-NSo3E99QDbYSMeJaEk9YW2lTg3qS9V0aKGlb+PlOrei1X02r1wSBHCNX/O+yeTRFSWPKPIGj6MqvvdqV4rnVGw==
  dependencies:
    commander "~2.17.1"
    source-map "~0.6.1"
    source-map-support "~0.5.6"

After update we have this (errors in "Environment" section below)

terser@^3.8.1:
  version "3.16.0"
  resolved "https://registry.yarnpkg.com/terser/-/terser-3.16.0.tgz#04028e6e5da461d91691cedd75fa53a17f2f20d9"
  integrity sha512-Ua8BhyibmsQBFXDZZ3Es7GASB2yFrQJr0jgAlZK1FBLbFarrHoCuMHPCro5MbX4jidcaFGiV+uTc3wxodmGjUg==
  dependencies:
    commander "~2.17.1"
    source-map "~0.6.1"
    source-map-support "~0.5.9"

Expected result

Prod build

Actual result

Prod build with error on js stage

deammer's suggested workaround above did not help build succeed for me but pitops suggestion on terser-webpack-plugin did:

As a workaround for now if you use yarn you can add a resolution to a fixed terser version. Delete yarn.lock first and node_modules

Example (in your package.json)

"resolutions": {
  "terser": "3.14.1"
}

YMMV but thought I would drop it in here in case it helps someone else.

I get the same errors with the latest packges - reverting to the versions I had before avoids this error.

Looks like a problem with terser-webpack-plugin:
https://github.com/terser-js/terser/pull/254

Here's the simplest workaround at the moment:

# npm
npm i --save-exact --save [email protected]

# yarn
yarn add [email protected] --exact

This was fixed in https://github.com/terser-js/terser/commit/03b08760fcac9ee3f633d7c8e82af417c47db4e7

Updating terser to v3.16.1 should fix this, closing this for now

Updating our terser-webpack-plugin dependency to always be higher than 1.2.2 so no one sees this anymore

terser is on 5.5.0 still broken
