How to add /usr/local/bin in $PATH on Mac

When I do 'open .profile' in the terminal I have the following:

export PATH=$PATH:/usr/local/git/bin 

Now I installed node.js for Mac and it says,

Make sure that /usr/local/bin is in your $PATH.

How can I add /usr/local/bin to export PATH=$PATH:/usr/local/git/bin?

export PATH=$PATH:/usr/local/git/bin:/usr/local/bin

One note: you don't need quotation marks here because it's on the right hand side of an assignment, but in general, and especially on Macs with their tradition of spacy pathnames, expansions like $PATH should be double-quoted as "$PATH".

Try placing $PATH at the end.

export PATH=/usr/local/git/bin:/usr/local/bin:$PATH

I've had the same problem with you.

cd to ../etc/ then use ls to make sure your "paths" file is in , vim paths, add "/usr/local/bin" at the end of the file.
