Vue add doesn't work when using Yarn Workspaces

[Spittal]

Version

3.0.4

Node and OS info

Node v10.11.0, Yarn 1.9.4

Steps to reproduce

In an existing project using the package.json field vuePlugins with a Yarn workspace like so...

"vuePlugins": {
    "resolveFrom": "someWorkspace"
  }

Run the command

vue add @vue/typescript

What is expected?

That the vue plugin is installed and the generator is invoked.

What is actually happening?

This error

📦  Installing @vue/cli-plugin-typescript...

yarn add v1.9.4
info Visit https://yarnpkg.com/en/docs/cli/add for documentation about this command.
error Running this command will add the dependency to the workspace root rather than the workspace itself, which might not be what you want - if you really meant it, make it explicit by running this command again with the -W flag (or --ignore-workspace-root-check).
 ERROR  command failed: yarn add -D @vue/cli-plugin-typescript

---

It should be noted that I also get similar errors when manually installing the required dependancies for the Vue-CLI plugin but when using a Yarn Workspace the vue invoke command also fails.

is the vue-cli project itself in a workspace?

It would really be helpful if you could provide a demo repository.

[Aircity]

Use .yarnrc
--add.ignore-workspace-root-check true

quick start:
vue add @o3o/packages

See: https://github.com/Aircity/vue-cli-plugin-packages

Seems to be resolved by @Aircity 's comment, and OP is inactive. Closing for now.

Hi @LinusBorg Sorry this took so long but here is a repo for reproduction. You can just clone this run yarn then run vue add @vue/cli-plugin-typescript

You should get:

📦  Installing @vue/cli-plugin-typescript...

yarn add v1.9.4

Sorry for the wait but thanks for taking a look at this.

I should mention that the .yarnrc fix does work, but I think it should probably be built into VueCLI or at least in the VueCLI docs alongside resolveFrom.

I added .yarnrc in my user folder and my project root, and I still get this issue

Adding my two cents in case it helps anyone else out:

I was running into a similar issue. Turns out one of my other packages was using a newer version of typescript which caused @vue/cli-plugin-typescript and typescript to be installed into my package's node_modules instead of the root one. I set both of my packages to use a compatible typescript version and the error went away.

Having a monorepo setup here.

I am using yarn workspaces. vue add eslint ran in the package folder tries to use npm but I want it to use yarn...

vue add eslint in the root folder gives me the same error error Running this command will add the dependency to the workspace.

I don't want to install it into the root, in want to run vue add ... inside the package folder..

I'm having the same issue. I'm also using a monorepo with yarn. I'm wanting to migrate to 3.0 using vue-next, but running the command in the root gives this error, and running the command in the package causes it to fail because it can't find my local dependency.
