How can I only install dependencies for a particular package managed by `nx`

I have a monorepo managed by nx. And I use yarn install to install dependencies. I found when I run yarn install under one package folder, it installs dependencies from other packages. packages/is-event/package.json packages/is-odd/package.json package.json node_modules Above is my project folder structure, I have one dependency in is-odd package, when I run yarn install in is-even package, the dependency from is-odd was downloaded and saved in the root level node_modules folder. How can I avoid downloading other packages' dependencies? I have removed the node_modules folder before running yarn install in is-odd folder.
