Python, install Pytables: ValueError: [u'path']

I use command 'pip install tables' in powershell (Windows) to install Pytables. Yet I receive the ValueError: [u'path']. In red is written 'Command "python setup.py egg_info" failed with error code 1'. I have miniconda installed.

EDIT: the full red error message is the following:

'Command "python setup.py egg_info" failed with error code 1 in c:\users\evert\appdata\local\temp\pip-build-9wkucl\tables
\'

Between my pip install command and the red error message is written the following:

Collecting tables
  Using cached tables-3.2.2.tar.gz
    Complete output from command python setup.py egg_info:
    * Using Python 2.7.11 |Continuum Analytics, Inc.| (default, Feb 16 2016, 09:58:36) [MSC v.1500 64 bit (AMD64)]

      File "c:\users\evert\miniconda2\lib\distutils\msvc9compiler.py", line 299, in query_vcvarsall
        raise ValueError(str(list(result.keys())))
    ValueError: [u'path']

Which part is missing? Which steps should I execute before running 'pip install tables'? Thank you for your help.

This is a problem with not being able to correctly setup certain environment variables required for the setup using vcvarsall.bat. You can download a binary of pytables here instead and do pip install tables-3.2.2-*.whl. Be sure to download the binary matching your version and system architecture.
