have added lerna to my project, i have added a package to my server by running this command successfully:

 lerna add  @types/express --dev

But when I want to add another one:

lerna add graphql class-validator type-graphql

I got this error :

info cli using local version of lerna
lerna notice cli v3.22.1
lerna WARN No packages found where graphql can be added.
  1. Is something missed or wrong for adding the packages?
  2. Should I use yarn add instead of leran add? looks it works but I doubt about the packages tree form to be correct

At the moment, lerna doesn't support adding multiple packages to another package like so:

❌ lerna add '@my-company/{utils,types}' --scope '@my-company/ui' 

// We have to do this instead
lerna add '@my-company/utils' --scope '@my-company/ui' 
lerna add '@my-company/types' --scope '@my-company/ui'

Lerna does support adding 1 package into multiple packages though:

lerna add '@my-company/utils --scope '@my-company/{ui,data}'

lerna's github discussion on this issue for updates (link)

Lerna add does not support multiple packages, try doing one at a time.

lerna add graphql
lerna add class-validator
lerna add type-graphql

There is an issue to support this on github that will hopefully be resolved one day

  • it's weird that I can add type dependencies as mentioned, but having the same error while adding a package, I just tried `lerna add express-graphql` – Amir Meyari Jul 20 '20 at 17:23
  • I am not sure, I do not use type script. The only difference I can see is that @types is an org package where as the others are single packages? – Frank Jul 20 '20 at 19:55
  • This is a super-confusing message from Lerna. I thought I'm typing the `--scope`'s name wrong, but I was actually trying to add multiple packages at once, that was the issue – Ilya Kushlianski Apr 25 '21 at 23:12

Foreword: The lerna cli is notoriously bad at giving feedback. You get weird errors and warnings that don't seem to make a lot of sense in the context.

Why is this happening?

I identified the following causes (at one point or another) to all result in this error message:

  1. You already added the package to given package.
    • This is somewhat irritating, since with yarn and npm you can (force) re-install a package, instead of having it error out.
  2. You tried to add multiple packages in one command (this is also mentioned in other answers and comments here).

Old question, but I ran into the same issue with "lerna": "^5.5.2" trying to only install a single dependency.

Ran lerna repair --verbose and it highlighted issues with the version of Nx. Once fixed I could install deps again. Granted, you might not have Nx integrated, but the repair command will give you more insights into what could potentially be the issue.

As per @Domi's answer Lerna's CLI is still not very forthcoming with feedback.
