Workaround

I created a dummy "npm" binary that simply ran yarn w/ the args. (I should not have to do this)

@urkle do you have the code for me? Im having the same issue here

[urkle]

@yooouuri this is fixed in recent versions of Vue cli (at least for create)

@urkle

Sadly it is not for vue add ... and vue upgrade ....

I am using a monorepo with (for now) one Vue project.

When I run for example vue add vuex in the root of my monorepo, it tries to add it to the root (with yarn). Ofc I don't want that. When I run vue add vuex inside the Vue project package (packages/vue-project), it forces me to use npm...

I've opened #5150 to fix this issue.

Thanks, would be nice to see this issue to be fixed. Had to write an ugly fix...

Removed npm, added the following script (as npm) to my path.

#/bin/sh

args=("$@")

echo $args

if [ "${args[0]}" == "install" ]; then
    echo "lets fake the npm install"

    # where args[3] is for example @vue/cli-plugin-eslint and args4 is -D
    if [ "${args[3]:0:4}" == "@vue" ]; then
        yarn add ${args[3]} ${args[4]}
    # if we are not installing any package, install all depencencies
    else
        yarn install
    fi
