copied!<p>pip uses Setuptools, and doesn't require any changes to packages. It actually installs packages with Setuptools, using:</p> <pre><code>python -c 'import setuptools; __file__="setup.py"; execfile(__file__)' \ install \ --single-version-externally-managed </code></pre> <p>Because it uses that option (<code>--single-version-externally-managed</code>) it doesn't ever install eggs as zip files, doesn't support multiple simultaneously installed versions of software, and the packages are installed flat (like <code>python setup.py install</code> works if you use only distutils). Egg metadata is still installed. pip also, like easy_install, downloads and installs all the requirements of a package. </p> <p><em>In addition</em> you can also use a requirements file to add other packages that should be installed in a batch, and to make version requirements more exact (without putting those exact requirements in your <code>setup.py</code> files). But if you don't make requirements files then you'd use it just like easy_install.</p> <p>For your <code>install_requires</code> I don't recommend any changes, unless you have been trying to create very exact requirements there that are known to be good. I think there's a limit to how exact you can usefully be in <code>setup.py</code> files about versions, because you can't really know what the future compatibility of new libraries will be like, and I don't recommend you try to predict this. Requirement files are an alternate place to lay out conservative version requirements.</p> <p>You can still use <code>python setup.py develop</code>, and in fact if you do <code>pip install -e svn+http://mysite/svn/Project/trunk#egg=Project</code> it will check that out (into <code>src/project</code>) and run <code>setup.py develop</code> on it. So that workflow isn't any different really.</p> <p>If you run pip verbosely (like <code>pip install -vv</code>) you'll see a lot of the commands that are run, and you'll probably recognize most of them.</p>
