[BUG] Deprecation Warning on Nuxt.js build due to package.json export #140

danperks · 2024-02-07T18:13:29Z

When building my Nuxt.js project which uses this package, I get a bunch of deprecation warnings, following this format:

(node:2848) [DEP0166] DeprecationWarning: Use of deprecated double slash resolving ".//index.json" for module request ".//index.json" matched to "./*" in the "exports" field module resolution of the package at [PROJECT PATH]\node_modules\@iconify\vue\package.json imported from [PROJECT PATH]\node_modules\nitropack\node_modules\_index.js.

This looks to be referring to this line in the Iconify package.json:

https://github.com/iconify/iconify/blob/a8e3b45ecd56e194fd8ef2c3b4eeb6f8c4e68bb1/components/vue/package.json#L27

Have I got a configuration issue, or is this a bug in this library or the Iconify one?
Haven't found any previous reports of this, so this could just be an issue with my project.

I'm on Node v18.17.0, Nuxt v3.8.0 and NuxtIcon v0.6.1
Thanks :)

The text was updated successfully, but these errors were encountered:

hmingv · 2024-02-22T07:38:27Z

I have the same problem

Node v20.1
Nuxt V3.10.2
Nuxt-Icon v0.6.8

This looks to be referring to this line in the Iconify package.json:

https://github.com/iconify/iconify/blob/a8e3b45ecd56e194fd8ef2c3b4eeb6f8c4e68bb1/components/vue/package.json#L27

I tried removing the line specified in the above link and the error disappeared.

I'm executing pnpm build

cyberalien · 2024-02-22T07:56:46Z

I've seen this issue in another project after recent update when import path ends with /

Maybe there is import somewhere in code that ends with /, like tries to import from @iconify/vue/? I can't find such code.

hmingv · 2024-02-23T02:36:54Z

Since I couldn't determine the source of the problem, I used the stupidest way to test (deleting files one by one, you need to delete node_modules at the same time and repackage)

When I encountered the .npmrc file, I removed the shamefully-hoist=true line and the problem was solved.

I'm not sure if there's any connection, but it does solve my problem for now

KarelVendla · 2024-02-26T15:44:58Z

I also have this in my project

Running
node 20.11.0
nuxt 3.8.2
nuxt-icon 0.6.8

ausir0726 · 2024-03-28T08:19:49Z

After my investigation, nuxt starter will write a .npmrc file before September 2023 that includes shamefull-hoist=true. This will cause an issue when running pnpm build. However, this file has been removed as of September 2023. Therefore, if the project was created before, it may still have this file.

No longer see this warning after manually removing the file.

nuxt/starter@9afba5d

@hmingv Thank you for your helpful response, it saved me from being stuck here like you.

lx-elephantxiang · 2024-04-17T10:51:53Z

@hmingv I removed the shamefully-hoist=true line and the problem still exists；

Kram-V · 2024-04-23T09:58:56Z

Are you encountering guys right after you push ur updates in production, the nuxt application will be delayed for a bit of seconds in every page that I navigate? when I already went there on every page, it will become normal navigation again, there's no delay. Is there any connections about this warning or issue of @iconify/vue/ ? btw I deployed my nuxt app using npm run build for ssr in vercel. TIA

kleinpetr · 2024-04-30T09:51:55Z

same here, after upgrading Nuxt from 3.9.3 to 3.11.2

Kram-V · 2024-04-30T09:56:18Z

@kleinpetr can we downgrade the nuxt app?

kleinpetr · 2024-04-30T09:58:18Z

@Kram-V yes, when I downgrade to 3.9.3 the build has no issue

Kram-V · 2024-04-30T10:21:20Z

@kleinpetr ok tnx

kleinpetr · 2024-04-30T10:25:46Z

@Kram-V oh sorry, it seems that I am getting these warning also with locked 3.9.3 🤔 so in my case it's because I removed pnpm.lock after a while, so some deps was cached probably, so cannot specifically...

cyberalien · 2024-04-30T10:26:51Z

@Kram-V oh sorry, it seems that I am getting these warning also with locked 3.9.3 🤔 so in my case it's because I removed pnpm.lock after a while, so some deps was cached probably, so cannot specifically...

Try running pnpm dedupe

Kram-V · 2024-04-30T10:32:59Z

btw @kleinpetr how can you downgrade ur nuxt app with specific version?

Kram-V · 2024-04-30T10:47:15Z

@kleinpetr I removed the node_modules and package-lock.json and change the version of my nuxt app into ^3.9.3 but when I npm run dev the pop up in the terminal still Nuxt 3.11.2 why is that?

cyberalien · 2024-04-30T10:48:22Z

Remove ^ from version number

Kram-V · 2024-04-30T10:52:20Z

@cyberalien ok sir I will try

Kram-V · 2024-04-30T10:57:49Z

@cyberalien it worked, thank you so much sir!

onurusluca · 2024-04-30T14:39:38Z

Same here. Don't know when this started as I don't watch the whole build process.

These didn't work:

Deleting node_modules and lock file and .nuxt
Downgrading to nuxt 3.9.3
Removing shamefully-hoist=true
Using npm or yarn

Sharing my info just in case it helps with the debugging.

node: v20.11.1
pnpm: 8.15.4

Errors(getting like 500 errors like this on pnpm build, not just for iconify but for almost all the packages):

Issue similar to Iconify/iconify#283 exists.

Also, for Nuxt I recommend using iconify-icon package, not @iconify/vue. See Iconify Icon SSR for details.

DbPtZn · 2024-07-24T19:14:22Z

Me too.But it doesn't seem to affect the program's operation

antfu · 2024-07-28T12:52:04Z

Can anyone send a minimal reproduction so I can have a deeper look?

ojvribeiro · 2024-07-28T20:37:53Z

@antfu here is the repro: https://github.com/ojvribeiro/nuxt-repro-deprecation-warning

It is a fresh Nuxt project and Nuxt Icon is the only module installed. When I run the build command the Deprecation Warning message is spammed:

cyberalien · 2024-07-28T20:47:56Z

@antfu here is the repro: https://github.com/ojvribeiro/nuxt-repro-deprecation-warning

That reproduction doesn't show any warnings when running build command on MacOS or Linux.

Looking at this screenshot and previous screenshots, all reports use \ in path, so looks like a Windows only issue.

Sorry, but not for now. Had this in issue in a private project with many dependencies. Probably, will share a reproduction if the problem will remain and I'll have more time to investigate.

thyngster · 2024-08-28T01:39:19Z

I was "trying" to find a fix for this. My current test env,. is latest nuxt + latest vueuse .

  "dependencies": {
    "@vueuse/core": "^11.0.3",
    "nuxt": "^3.13.0",
    "vue": "latest"
  },

I'm seeing the issue also happening only starting from Nitro 2.6.0 ( ie downgrading to 2.5.2 will prevent the error to show up ) , not the best option since for example there's not ESM WASM support.

So not sure if this is totally related to Nuxt part or Nitro at all.

Also not only DEP0166 is triggered also the DEP0155. may be it related at some poting to nitrojs/nitro#2523 ?

WilliamFalci · 2024-09-18T04:46:14Z

Hello guys,

by all my test:

OS: Window
Node: 18.x - 20.x - 22.x

I confirm the issue is only on Windows, after windows I tried Ubuntu and everything worked without changes

dencs08 · 2024-09-19T10:32:15Z

Running pnpm build or npm run build throws

Use of deprecated trailing slash pattern mapping... or Use of deprecated doulbe slash resolving...

It happens only on windows while on macos it builds perfectly fine.

itpropro · 2024-09-20T04:39:52Z

Just in case anyone comes across this and wants to suppress the errors, you can prepend you script in your package.json with this under Windows until the bug is fixed:

set NODE_OPTIONS=--disable-warning=DEP0155 --disable-warning=DEP0166 &&

  "scripts": {
    "build": "set NODE_OPTIONS=--disable-warning=DEP0155 --disable-warning=DEP0166 && nitro build",

cross-env would be the better choice for cross platform, but this is just temporary until the cause was found.
