初学者安装nosetests包

Question

I'm trying to install the following as per the learnpythonthehardway tutorial:

1. pip from http://pypi.python.org/pypi/pip
2. distribute from http://pypi.python.org/pypi/distribute
3. nose from http://pypi.python.org/pypi/nose/
4. virtualenv from http://pypi.python.org/pypi/virtualenv

I've visited these links and clicked the download button; each file is in my downloads folder now, and I unarchive/unzipped them- not sure what this means but it seemed required. Are they "installed"? If not, what does it mean to really install them? I've tried typing nosetests in the terminal (as the book says you should), as well as tried easy_install but that doesn't seem to work. It appears my understanding is limited in a number of ways here.

I get the following -bash: nosetests: command not found , but am trying to get:

nosetests . ---------------------------------------------------------------------- Ran 1 test in 0.007s OK

This works on mac, it may work on linux

2)Type: sudo easy_install pip

3)Type: sudo pip install distribute

4)Type: sudo pip install nose

5)Type: sudo pip install virtualenv

Hope that helps, cheers!

Answer 2

They are not yet installed. Each has its own vagaries about how exactly the install process works and in fact some of those packages will include the other packages with them. Ie

"If you use virtualenv, a copy of pip will be automatically be installed in each virtual environment you create."

As a relatively new python user myself, (and having gone thru a similar process not long ago) I am eagerly awaiting the more complete answers that come back for this one.

Answer 3

Find out where the nosetests script is. On OSX:

/usr/local/share/nosetests

Execute directly, or set up a bash alias, perhaps in .bash_profile:

alias nosetests='/usr/local/share/python/nosetests'
alias nosetests3='/usr/local/share/python3/nosetests'

Answer 4

You were on the right track, but the package is actually called "nose". The documentation for nose (nosetests is the script) can be found here: https://nose.readthedocs.org/en/latest/

The short answer is that you have 2 basic options: easy_install or pip . Install using setuptools/distribute: easy_install nose . Install using pip: pip install nose

Answer 5

Install Python 2.7 and after just do this (only on Windows - Windows PowerShell):

1. Setup PATH env:

C:\\Python27\\;C:\\Python27\\Scripts\\", "User"

2. pip is already installed

3.

.\pip install distribute

4.

.\pip install nose

5.

.\pip install virtualenv
