Use different name from express while initializing npm i.e while doing npm init

In your package.json check key name

"name": "express"

replace express to some other name then your error will be resolved.

If the folder name and the package.json name key is the same as the module name like this

terminal:

npm install express

json file:

// express/package.json

{
  "name": "express",
  "version": "1.0.0",
  "description": "",
  .
  .
  .
}

... < Error >.

To solve that:

json file:

// <foldername>/package.json

{
  "name": "newName",
  "version": "1.0.0",
  "description": "",
  .
  .
  .
}

Then

terminal:

npm install express

well I know what is the exact problem with you and that is, while creating the project by

npm init

you have given the name as the dependency name.

So change Name of your project by going into package.json and give a different name. And then install again by the same command like

npm install --save

and I can say that you will not get the same error again

When start a node project, you need to use command npm init in target folder. Then install express module.

You're running npm i express --save being located inside ExpressJS folder. Please go outside and install express there.
