PyPy's speed promises make me want to try it. Unfortunately, none of the tutorials I read on the subject really helped me to understand the very basics, namely how to (in simple steps):
- Install PyPy on Mac
- Run a .py script
I read that downloading, extracting and running pypy myscript.py from bin/ should do the trick, but no luck for me so far. Here's what I get:
MyMacbook:bin User$ pypy myscript.py
-bash: pypy: command not found
Could anyone help me understand PyPy's basic usage?
Answer
Have you tried using homebrew (http://brew.sh/)?
~ $ brew search pypy
pypy
Looks like a "brew install pypy" should get you there.
~ $ brew versions pypy

Please use the homebrew-versions tap instead:

edit: Alternatively have you checked whether or not you've put your install on your path? For instance, I grabbed it and put it into my home directory.
~ $ ll ~/ | grep pypy
drwxr-xr-x@ 9 squiddly staff 306 Nov 27 07:42 pypy-2.2.1-osx64
Then in my .bash_profile I put the following line in:
# Put pypy on my path
PATH=$PATH:$HOME/pypy-2.2.1-osx64/bin
export PATH
Now I can run pypy ~/scripts/test.py from wherever I want.
---- edit 2 ---- To answer the last question regarding the packages being missing:
"If you want to install 3rd party libraries, the most convenient way is to install distribute and pip:"
$ curl -O http://python-distribute.org/distribute_setup.py
$ curl -O https://raw.github.com/pypa/pip/master/contrib/get-pip.py
$ ./pypy-2.1/bin/pypy distribute_setup.py
$ ./pypy-2.1/bin/pypy get-pip.py
$ ./pypy-2.1/bin/pip install pygments # for example
"3rd party libraries will be installed in pypy-2.1/site-packages, and the scripts in pypy-2.1/bin"
