npm – Problem with node commands running because it has not been installed with administrator rights

I've installed the node without having administrator rights and this has been a success, but I often encounter errors as shown below. Is this a problem with the installation without administrator rights or something else? The errors I receive are: –

  1. npm ERR! ERR_STREAM_WRITE_AFTER_END code
    npm ERR! write after the end
  2. Unrecognized npx command (npm version is 6 and installed correctly)
  3. In the command visuall studdio terminal npm issues a denied access error
  4. I've tried to clear the cache (cache npm clean –force, cache check npm) still does not work

Is installation without administrator rights a cause for that or am I wrong with something else?
