Error: Command failed: npm config --location=project set legacy-peer-deps=true

I'm using turborepo (a monorepo framework) and npm, and I'm trying to run the command npx gluestack-ui add menu in my ./apps/mobile package, but end up with this error:

npm error code ENOWORKSPACES
npm error This command does not support workspaces.
npm error A complete log of this run can be found in: /home/onyedikachi23/.npm/_logs/2025-09-17T05_28_35_671Z-debug-0.log

■  Error: Command failed: npm config --location=project set legacy-peer-deps=true

I guessed it was trying to set the legacy-peer-deps=true flag, so I manually added it in the .npmrc files at the project root and inside the ./apps/mobile, but the error persisted.

Please note that the cli commands were working fine when I haven't moved the project to a monorepo structure.

That’s expected with monorepo setup — npm workspaces don’t allow running npm config --location=project inside a sub-package. You’ll need to run the install from the root and specify the workspace, for example:
npm install @gluestack-ui/menu -w apps/mobile
This way the package gets added to your apps/mobile workspace correctly.

I'm confused here. What command should I run at the root? npx gluestack-ui add menu or npm install @gluestack-ui/menu -w apps/mobile?

npx gluestack-ui add menu -w apps/mobile try running this

[onyedikachi23]

I've tried, but got this:

npx gluestack-ui add menu -w apps/mobile
# error: unknown option '-w'

[onyedikachi23]

This command worked:

npx gluestack-ui add menu --path=apps/mobile

But it added the component in the root of apps/mobile, and with v3 code. I had to manually refactor to v2 and running npm i @gluestack-ui/menu manually.

Hi @onyedikachi23 ,
Thanks for trying that out and sharing the details
We’re aware of this issue with monorepo setups, and our team is already working on improving the CLI to handle workspace paths more smoothly.
We’ll update you soon once the fix is ready 🚀
