title: How to install pytables 3.2 on anaconda?
body: <p>I use anaconda, and I cannot upgrade with </p>
  
  <pre><code>conda update pytables
  </code></pre>
  
  <p>it says "already installed". </p>
  
  <pre><code>....
  # All requested packages already installed.

  </code></pre>
  
  <p>Then I tried pip:</p>
  
  <pre><code>C:\Users\HP&gt;pip install --upgrade tables
  Collecting tables
    Using cached tables-3.2.0.tar.gz
      Complete output from command python setup.py egg_info:

      .. ERROR:: Could not find a local HDF5 installation.
         You may need to explicitly state where your local HDF5 headers and
         library can be found by setting the ``HDF5_DIR`` environment
         variable or by using the ``--hdf5`` command-line option.

  </code></pre>
  
  <p>I searched my hard disk, and couldn't find <code>hdf5dll.lib</code> file.
  Then I downloaded the latest HDF5-1.8.15 Patch1 and point <code>HDF5_DIR</code> to the installed directory, still same error, and there's no <code>hdf5dll.lib</code> file in the newly installed HDF5 directory either. </p>
