iambumblehead · 2023-09-10T01:54:59Z

Is there an existing issue for this?

I have searched the existing issues

This issue exists in the latest npm version

I am using the latest npm

Current Behavior

npm --version and other commands print a runtime error

$ npm --version
/usr/lib/node_modules/npm/lib/es6/validate-engines.js:31
    throw err
    ^

Can you try [email protected] which is the latest versions? Also how did you download this version of npm? 10.0.0-1 isn't a valid version of npm in the registry:

npm view npm --json versions
[
  ...
  "10.0.0-pre.0",
  "10.0.0-pre.1",
  "10.0.0",
  "10.1.0"
]

@lukekarrys thank you and my apology for opening this issue here. This should have been opened at the arch package location instead https://gitlab.archlinux.org/archlinux/packaging/packages/npm/-/blob/main/PKGBUILD?ref_type=heads

respectfully, I will close this issue

blacklight · 2023-09-14T21:32:25Z

@iambumblehead I've been experiencing the same issue on all of my Arch installations as well after upgrading to npm 10.

Downgrading to 9.8.1 is a temporary workaround.

Have you already reported the issue to the Arch maintainer? I couldn't find anything here https://bugs.archlinux.org/?project=1&string=npm.

I can open a ticket on the Arch side as well if you prefer.

iambumblehead · 2023-09-14T21:53:27Z

@blacklight please open a ticket :) I do not have an account there and did not open a ticket

blacklight · 2023-09-14T22:33:11Z

@iambumblehead ok FYI I've filed a bug report on Arch here https://bugs.archlinux.org/task/79693

iambumblehead · 2023-09-14T22:49:03Z

thanks. toolybird's comment un-necessarily rude

blacklight · 2023-09-14T23:48:07Z

@iambumblehead I've found the culprit and a solution - see comment on the Arch Linux thread.

Long story short, the error most likely happens when you have (or had at some point) an old version of semver installed - either an old semver package or something installed via npm install -g.

Uninstalling npm+semver, removing /usr/lib/node_modules/npm/node_modules/semver and reinstalling it should fix it.

iambumblehead · 2023-09-15T00:02:02Z

@blacklight yes that works thank you!

$ sudo pacman -R npm semver node-gyp
$ sudo rm -rf /usr/lib/node_modules/npm/node_modules/semver
$ sudo pacman -S npm semver
$ npm --version
10.1.0

I'm curious, how tf did you find that out?

antonis-tsolomitis · 2024-02-11T13:26:10Z

The above fix does not work now. After
sudo pacman -Syu
sudo pacman -R npm semver node-gyp
rm -rf /usr/lib/node_modules/npm/node_modules/semver
sudo pacman -S npm semver

The command

npm --version

gives
/usr/lib/node_modules/npm/lib/es6/validate-engines.js:31
throw err

Why would you install an npm package via pacman? use npm.

blacklight · 2024-02-11T16:31:21Z

Why would you install an npm package via pacman? use npm.

Installing packages via npm install -g is exactly what seems to cause the issue in these cases.

When npm is upgraded via pacman it also upgrades anything under /usr/lib/node_modules, if those packages were installed via pacman too.

If they were installed via npm instead, then those old dependencies are likely to stay there. If they are incompatible with the new version of npm, then you'll have this kind of errors.

As a general advice, global packages should always be installed through the system package manager, if they are available. npm install -g is likely to break system dependencies just like sudo pip install.

The above fix does not work now

If the error doesn't come from gyp/semver now then it may come from another dependency installed via npm install -g.

My way of pinpointing the culprit usually works, but it's a bit cumbersome - not sure if there's a smarter way of telling which dependencies weren't installed via pacman.

Backup your /usr/lib/node_modules and /usr/local/lib/node_modules folders and remove them
Reinstall node+npm
Verify that the error no longer occurs
Reinstall all the dependencies in your previous node_modules via pacman. Or try and move the modules folders back one by one to test which one causes the error

antonis-tsolomitis · 2024-02-11T16:47:34Z

I backed up each of the above folder and removed it.
pacman -R npm semver node-gyp

then

pacman -S npm

accepted the semver and node-gyp dependencies and all installed.

Now npm --version fails again, now with:

/usr/lib/node_modules/npm/lib/es6/validate-engines.js:31
throw err
^

antonis-tsolomitis · 2024-02-11T16:49:25Z

Ah, I installed nodejs-nopt and now it works! Thank you.

The folders I had backed up are: corepack, root, vdx and node-gyp, nopt, npm, semver which where installed again by pacman. I guess these are needed... how do I install them with pacman (I mean corepack, root, vdx)?

blacklight · 2024-02-11T16:58:26Z

how do I install them with pacman (I mean corepack, root, vdx)?

It may be that they are no longer required by recent versions of node - I'm on the latest version and my node_modules doesn't seem to contain those folders any longer.

antonis-tsolomitis · 2024-02-11T17:03:41Z

OK. Great!

devsnd · 2024-04-07T17:55:07Z

I had a few other modules that did not work after having reinstalled npm and semver as recommended by @blacklight .

I also needed to manually delete the node_modules that were part of the npm install, so to fix it on arch I did:

$ sudo pacman -R npm semver node-gyp
$ sudo rm -rf /usr/lib/node_modules/npm  # note that I removed the whole npm directory this time
$ sudo pacman -S npm semver
$ npm --version
v21.7.2

Note: This obviously nukes your globally installed node_modules, but I wanted a clean state to work off of

sarthakgupta898 · 2024-04-24T12:05:51Z

What is the workaround for windows?

AlonaAkimova · 2024-04-24T15:58:45Z

Hello,

Error is in this line: https://github.com/npm/node-semver/blob/ec49cdcece9db0020d6829b246681ff65a393644/classes/range.js#L201

It has been introduced in semver 7.3.3.

The new version 7.6.1 is released and will solve the problem. Related MR here:
npm/node-semver#706.

Solution is to upgrade to 7.6.1 or downgrade to 7.3.2

If you want to downgrade add below to your package.json:

NPM:

{
   "overrides": {
     "semver": "7.3.2"
   }
 }

Yarn:

"resolutions": {
    "semver": "7.3.2"
}

Hope it helps.
