Command failed with exit code 1 (EPERM): npx install-peerdeps --yarn next-sanity@9

[lhoucinecherif]

Describe the bug

I'm encountering an issue while trying to initialize Sanity for a Next.js project. The install-peerdeps command fails with a permission error despite multiple attempts with different approaches. Here are the details:

To Reproduce

Steps to reproduce the behavior:

1.Install a next boilerplate
git clone https://github.com/next-enterprise.git
cd next-enterprise
yarn install --frozen-lockfile

2. Install sanity over the next project
   npx sanity@latest init --env --create-project "Next.js Live Preview" --dataset production

3. Answering CLI questions like this :

• Would you like to add configuration files for a Sanity project in this Next.js folder? Yes
• Do you want to use TypeScript? Yes
• Would you like an embedded Sanity Studio? Yes
• What route do you want to use for the Studio? /studio
• Select project template to use Clean project with no predefined schema types
• Would you like to add the project ID and dataset to your .env file? Yes

Expected behavior

The command should init & install all necessary peer dependencies for sanity inside the existing nextjs project

Which versions of Sanity are you using?

sanity: command not found

What operating system are you using?

Distributor ID: Ubuntu
Description: Ubuntu 22.04.4 LTS
Release: 22.04
Codename: jammy

Which versions of Node.js / npm are you running?

Run npm -v && node -v in the terminal and copy-paste the result here.

npm 10.8.1
node v20.15.0

Additional context

This is the last lines of the console output :

Hi @lhoucinecherif. Please can you double check the URL of the boilerplate you cloned? https://github.com/next-enterprise.git is not a valid GitHub repository.

Running into a similar problem.

Trying to port an exisiting next-js project to be using sanity. Have "next": "^14.2.3", in my package json

With yarn, running npx install-peerdeps --yarn next-sanity as mentioned on https://www.npmjs.com/package/next-sanity/v/4.1.5#yarn

Response:

install-peerdeps v3.0.3
Installing peerdeps for next-sanity@latest.
yarn add next-sanity@9.4.3 @sanity/client@^6.20.1 @sanity/icons@^3.0.0 @sanity/types@^3.37.1 @sanity/ui@^2.0.11 next@^15.0.0 react@^19.0.0 sanity@^3.37.1 styled-components@^6.1

ERR undefined

The undefined error makes it hard to triage. But I am guessing it trying to install next 15 in a next 14 project is probably part of the issue.

Facing the same issue

[luizlevindiniz]

Yeah, I have gotten the same issue while following this sanity tutorial https://www.sanity.io/guides/nextjs-app-router-live-preview#46870b28c449

I've made some research and it seems that the root cause is a node issue, check those links:
nodejs/node#52554

its next v15

[kolkol69]

for me, installing deps manually fixes the problem

yarn add next-sanity@9.5.0 next@^15.0.0 react@^19.0.0 sanity@^3.57.4 @sanity/ui@^2.8.9 @sanity/icons@^3.4.0 @sanity/types@^3.57.4 @sanity/client@^6.21.3 styled-components@^6.1

Same here, did everything as I always do:

First npx create-next-app@latest, cd into it and pnpm create sanity@latest. Then the same error appears.

Error displays:
Found: react@19.0.0-rc-66855b96-20241106 when it expects react@"^18.3 || ^19.0.0-0".

What I did is just use an older next.js version until everything is stable: npx create-next-app@14.2.4

Hello all! We recently did some due diligence around our dependencies. Would you please let me know if you're still experiencing issues? If not, we can close this issue in the coming week. Thank you!

Just tried it today and having the same issue

project is a next.js 15 and react 19 projcect

then run this

pm create sanity@latest -- --project <projectId> --dataset production --template blog --typescript --output-path studio-e

the got the following output

install-peerdeps v3.0.3
ERR undefined

Error: Command failed with exit code 1 (EPERM): npx install-peerdeps --yarn next-sanity@9
    at error (~/.npm/_npx/67a0730928194b24/node_modules/@sanity/cli/lib/_chunks-cjs/cli.js:18524:32)

    at async initSanity (~/.npm/_npx/67a0730928194b24/node_modules/@sanity/cli/lib/_chunks-cjs/cli.js:52933:130)

when I run that again I get the following

 npx install-peerdeps --yarn next-sanity@latest
install-peerdeps v3.0.3
ERR undefined

[nathanhleung]

This was an issue on the install-peerdeps side, specifically for users of Yarn >1. I just pushed a fix which is live in the latest release, v3.0.6, that should resolve this issue.

[bjoerge]

Thank you @nathanhleung! Closing this issue then.

[bamofah]

@nathanhleung just tried it and I get the following output

`install-peerdeps v3.0.6
ERR {"type":"error","data":"This project's package.json defines "packageManager": "yarn@4.7.0". However the current global version of Yarn is 1.22.22."}

Presence of the "packageManager" field indicates that the project is meant to be used with Corepack, a tool included by default with all official Node.js distributions starting from 16.9 and 14.19.
