AWS CodeBuild does not work with Yarn Workspaces

问题

I'm using Yarn Workspaces in my repository and also using AWS CodeBuild to build my packages. When build starts, CodeBuild takes 60 seconds to install all packages and I'd want to avoid this time caching node_modules folder.

When I add:

cache:
  paths:
    - 'node_modules/**/*'

to my buildspec file and enable LOCAL_CUSTOM_CACHE, I receive this error:

error An unexpected error occurred: "EEXIST: file already exists, mkdir '/codebuild/output/src637134264/src/git-codecommit.us-east-2.amazonaws.com/v1/repos/MY_REPOSITORY/node_modules/@packages/configs'".

Is there a way to remove this error configuring AWS CodeBuild or Yarn?

My buildspec file:

version: 0.2
phases:
  install:
    commands:
      - npm install -g yarn
      - git config --global credential.helper '!aws codecommit credential-helper $@'
      - git config --global credential.UseHttpPath true
      - yarn
  pre_build:
    commands:
      - git rev-parse HEAD
      - git pull origin master
  build:
    commands:
      - yarn run build
      - yarn run deploy
  post_build:
    commands:
      - echo 'Finished.'
cache:
  paths:
    - 'node_modules/**/*'

Thank you!

Update 1:

The folder /codebuild/output/src637134264/src/git-codecommit.us-east-2.amazonaws.com/v1/repos/MY_REPOSITORY/node_modules/@packages/configs was being attempted to be created by Yarn, with the command - yarn at install phase. This folder is one of my repository packages, called @packages/config. When I run yarn on my computer, Yarn creates folders linking my packages as described here. An example of how my node_modules structure is on my computer:

node_modules/
|-- ...
|-- @packages/
|   |-- configs/
|   |-- myPackageA/
|   |-- myPackageB/
|-- ...
