This is all very new to me. After successfully installing meteor (which prompted for my user password, something not mentioned in any tutorials), I encountered an issue when attempting to create a new app with "meteor create myApp". The error message "meteor: command not found" suggests that meteor isn't functioning properly on my computer, despite the seemingly successful installation. Could I be overlooking something? Is there another component that needs to be installed too? My experience in development is limited to HTML only.
