After npm is released successfully, the contents of the package will remain old after npm install

My npm package export some variables

npm version 1.0.0

const info = {
  name:'tom'
}

When I changed the content

npm version 1.0.1

const info = {
  name:'joy'
}

I updated npm to 1.0.1 successfully in the project, add import its

but info.name is still tom

How do I keep the imported data up to date
