ERROR - Config value 'plugins': The "multirepo" plugin is not installed

[navi771]

When i installed multirepo plugin using this command "pip install mkdocs-multirepo-plugin" in Window
Plugin installed eg: Requirement already satisfied: six>=1.5 in c:\users\xxshbrmn\appdata\local\packages\pythonsoftwarefoundation.python.3.11_qbz5n2kfra8p0\localcache\local-packages\python311\site-packages (from python-dateutil>=2.8.1->ghp-import>=1.0->mkdocs>=1.0.4->mkdocs-multirepo-plugin) (1.16.0)

and i configure plugins in .yaml file
eg:
plugins:
search
multirepo:
cleanup: true
keep_docs_dir: true

-When i am using "plugins" keyword in yaml then it getting error as below :

ERROR - Config value 'plugins': The "multirepo" plugin is not installed
Aborted with 1 Configuration Errors!

-But when i using "plugin" in yaml then project running but multirepo features not working
