Why am I getting command not found even though path to command exists in PATH variable?

On Mac OSX 10.10.1 I get command not found for anything installed in /usr/local/bin (however command is found if I use sudo) PATH variable contains this path. for example pip. Here are some lines from terminal:

---

Dylans-MacBook-Air:edX Dylan$ echo $PATH /Library/Frameworks/Python.framework/Versions/3.4/bin:/Library/Frameworks/Python.framework/Versions/3.4/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

Dylans-MacBook-Air:edX Dylan$ which pip

Dylans-MacBook-Air:edX Dylan$ sudo which pip

/usr/local/bin/pip

What could be causing this behaviour and how do I fix it?
