Fail to install PyX using Anaconda

I'm having problems installing python modules PyX, I received the following error when using pip:

$ pip install PyX
Collecting PyX
  Could not find a version that satisfies the requirement PyX (from versions: )
  Some externally hosted files were ignored as access to them may be unreliable (use --allow-external PyX to allow).
No matching distribution found for PyX

Then I tried conda install, but it cannot locate it. I also searched and found nothing. Then I tried pip allow external - doesn't work on either Cygwin or cmd:

$ pip install --allow-external pyx pyx
Collecting pyx
  Downloading https://downloads.sourceforge.net/project/pyx/pyx/0.14/PyX 0.14.tar.gz (2.5MB)
No files/directories in c:\cygwin\tmp\pip-build-vqqlqz\pyx\pip-egg-info (from PKG-INFO)

I've never seen such error before. Anyone here has some suggestion please (installed under Anaconda preferred)? Thank you very much in advance.

Solution

  • Okay here is one solution I just found. However, I still could not explain the previous errors.

    Upon trying to manually install PyX (go to the local PyX directory):

    $ python setup.py install
*** Sorry, this version of PyX runs on Python 3 only. ***
If you want to use PyX on Python 2, please use one of our old releases up to PyX 0.12.x, i.e. execute something like:

   pip install pyx==0.12.1

    So then I tried:

    $ pip install  --allow-external pyx pyx==0.12.1

    Then it worked. Thanks.
