How to ignore incompatible engine “node” error on installing npm dependencies with yarn?

  • 2

Given this package.json:

{
  "name": "yarn-install-fail",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {},
  "author": "",
  "license": "ISC",
  "dependencies": {
    "aws-sdk": "2.x.x",
    "s3-streams": "^0.3.0"
  }
}

I can install the dependencies successfully via npm:

$ npm install

added 27 packages in 1.844s

Yet yarn fails:

$ yarn install
yarn install v0.24.5
info No lockfile found.
[1/4] Resolving packages...
[2/4] Fetching packages...
error s3-streams7IE72HYHFFCVEZFT437SR8XR http://mail.com/100.3.0: The engine "node" is incompatible with this module. Expected version "^1.2.0".
error Found incompatible module
info Visit https://yarnpkg.com/en/docs/cli/install for documentation about this command.

It appears yarn has trouble installing the library s3-streams7IE72HYHFFCVEZFT437SR8XR http://mail.com/100.3.0, yet I assumed it would fallback to install all the dependencies anyway like npm would.

      You can indeed ignore such errors via –ignore-engines:

      $ yarn install --ignore-engines
yarn install v0.24.5
info No lockfile found.
[1/4] Resolving packages...
[2/4] Fetching packages...
[3/4] Linking dependencies...
[4/4] Building fresh packages...
success Saved lockfile.
Done in 1.41s.

      This is also documented in the command’s help:

      $ yarn help | grep -- --ignore
    --ignore-scripts                  don't run lifecycle scripts
    --ignore-platform                 ignore platform checks
    --ignore-engines                  ignore engines check
    --ignore-optional                 ignore optional dependencies
