yarn add command dosen't install package

Question

I have very simple node project where I'd like to add dotenv package by yarn package manager. I'm working on linux Ubuntu 20.04.3 LTS. I'm typing command:

yarn add dotenv

The output is:

error An unexpected error occurred: "npm/dotenv: Invalid URI \"npm/dotenv\"".

yarn manifest: 
  No manifest

  No lockfile

I don't know why is that. I'm using npm in another projects. Is it caused by mixture of them in operating system?

Looks that the NPM registry is misconfigured. Try running this command to reset registry URL:

yarn config set registry "https://registry.yarnpkg.com" -g
