Usually when you get EACCES errors a good start is to see whether you have write rights to the folder where npm is writing (you get that in your error, in this case it is /home/developer/.npm).
You can see if you have write rights by running
ls -l /home/developer/.npm
if you see something like
drwxr-xr-x 2 SOMEONE-ELSE SOMETHING-ELSE 4.0K Mar 26 16:43 bin
rather than
drwxr-xr-x 2 developer developer 4.0K Mar 26 16:43 bin
it means your user does not own that directory, so you might want to run
sudo chown -R $(whoami) $HOME/.npm
to get those rights.
