copied!<p>From what i've read about bundler — pip without virtualenv should work just fine for you. You can think of it as something between regular gem command and bundler. Common things that you can do with pip:</p> <ol> <li><p><strong>Installing packages (gem install)</strong></p> <pre><code>pip install mypackage </code></pre></li> <li><p><strong>Dependencies and bulk-install (gemfile)</strong></p> <p>Probably the easiest way is to use pip's requirements.txt files. Basically it's just a plain list of required packages with possible version constraints. It might look something like:</p> <pre><code>nose==1.1.2 django<1.3 PIL </code></pre> <p>Later when you'd want to install those dependencies you would do:</p> <pre><code>$ pip install -r requirements.txt </code></pre> <p>A simple way to see all your current packages in requirements-file syntax is to do:</p> <pre><code>$ pip freeze </code></pre> <p>You can read more about it <a href="http://pip.readthedocs.org/en/latest/user_guide.html#requirements-files" rel="noreferrer">here</a>.</p></li> <li><p><strong>Execution (bundler exec)</strong></p> <p>All python packages that come with executable files are usually directly available after install (unless you have custom setup or it's a special package). For example:</p> <pre><code>$ pip install gunicorn $ gunicorn -h </code></pre></li> <li><p><strong>Package gems for install from cache (bundler package)</strong></p> <p>There is <code>pip bundle</code> and <code>pip zip/unzip</code>. But i'm not sure if many people use it.</p></li> </ol> <p><strong>p.s.</strong> If you do care about environment isolation you can also use virtualenv together with pip (they are close friends and work perfectly together). By default pip installs packages system-wide which might require admin rights. </p>
