which wget returns error: /usr/bin/env: «node»: No such file or directory

I uninstalled nodejs the other day and now for some reason when I access it I get the error that node is not found. The argument of the which command can be anything.

> which wget                                                                                                                                                                        
/usr/bin/env: «node»: No such file or directory

However, if I install the node again, everything is fine:

> sudo pacman -S nodejs
...
