command not found when typing: ./Library/Python/3.4/lib/python/site-packages venv

The question was more or less asked, but it's still not clear to me what I have to do.

Are you trying to create a virtual environment or invoke one that has been created?

I'm trying to create it. I just installed it. I was following the tutorial: using virtualenv and Kenneth is running it for the first time, and he says he needs to add a path at minute 2:13. When I do mine: I get:

joseterrera (master) ~ $ sudo ./Library/Python/3.4/lib/python/site-packages venv
sudo: ./Library/Python/3.4/lib/python/site-packages: command not found
joseterrera (master) ~ $ ./Library/Python/3.4/lib/python/site-packages venv
-bash: ./Library/Python/3.4/lib/python/site-packages: Permission denied

[MOD: added ```bash formatting -cf]

venv is a built in package new in Python 3.3. The link has more help on invoking venv module. Try:

$ python -m venv -h

Careful which Python you are using. with Python 2 you'll get "no module named venv". With Python 3, you'll get the help message.

site-packages is a directory, which can not be executed. The path Kenneth uses is:

~/Library/Python/3.4/bin/virtualenv venv

where venv is the target name for the new virtual env directory. Then the environment would be invoked with:

. ./venv/bin/activate
