This is probably because bem-utils expects iojs right? https://github.com/jozanza/bem-utils/blob/master/package.json#L10

[sebmck]

Looks like bem-utils incorrectly sets the node engine option. We're technically doing the right thing here. npm by default doesn't enforce these sorts of restrictions which leads to incorrect packages like this. I'll leave this open while we continue to evaluate how much of a compatibility hazard this is. I'd recommend opening an issue on the bem-utils package to get this resolved on their side in the meantime.

I have two other packages that use engines: https://github.com/crocodilejs/frisbee/blob/master/package.json ("node": "6.0.0") and https://github.com/davidtheclark/cosmiconfig/blob/master/package.json ("node": "4"). The first is a dep of a react-native project I'm working on, and the second is a dep of Mozilla's debugger.html.

I don't think that npm warned me about either of them, or I just missed it in their output logs…

I hadn't realized that the engines field was semver before.

I should file an issue on Frisbee, and I don't even understand why the second has that entry, since npm doesn't care.

[hawkrives]

I got the impression from the docs that the --ignore-engines flag would ignore the engines field – I don't know what "ignoring" means in this case, but I'd assume that it's equivalent to npm's behavior of "warn but continue."

However, applying that flag doesn't seem to change anything– both cases that I gave above still exit when they encounter the field.

Should I file a new issue for "doesn't respect --ignore-engines"?

[hawkrives]

@jlongster just filed #638, which reports my --ignore-engines bug.

Another incompatible package: https://github.com/oncletom/crx/blob/master/package.json#L18

  "engines": {
    "node": ">=0.10",
    "iojs": ">=1.0.0 <2.0.0"
  },

Another:

error [email protected]: The engine "node" is incompatible with this module. Expected version "^5.3".

Shown inside parchment's package.json:

"node": ">= 5.3"

Running on Node 6.6.0

Did you install yarn from the package repository? If you did, you may want to take a look at this #812

[leebenson]

@hiendv - nope, just npm i -g yarn. Responded here with my env.

[jackycute]

Another:

error [email protected]: The engine "node" is incompatible with this module. Expected version "~4.1.1".
error Found incompatible module

In reveal.js package: https://github.com/hakimel/reveal.js/blob/master/package.json

"engines": {
    "node": "~4.1.1"
},

Running on node v6.6.0

[wmertens]

I think that, since #647 is merged and will presumably be part of a release soon, this can be closed?

[samccone]

resolved in #647

With latest version of Yarn, I stil get the issue on Debian 8.5.

error [email protected]: The engine "node" is incompatible with this module. Expected version ">= 6.9.0".

Installing the latest version of node (non-LTS) fixed the issue. some other issues came up but that's solved

Still getting the same issue even with yarn's latest (v0.24.5) and latest non-LTS node (v7.10.0).
