Anaconda – UnsatisfiableError: The following specifications were found to be in conflict

  • 0

When I was trying to install a module ‘pymc’ through anaconda environments, it showed the error message as follows:

UnsatisfiableError: The following specifications were found to be in
conflict:

  • blaze -> pyyaml -> python[version=’>=2.7,<2.8.0a0′] -> vc=9

  • blaze -> pyyaml -> yaml -> *[track_features=vc9]

  • pymc Use “conda info ” to see the dependencies for each package.

I am using Python 2.7.14, and I installed anaconda 1.6.9 on a Windows. I am new to Python. I first tried to use cmd to install the module pymc and I ran into a lot of problems such as the requirement for install g77 compiler on windows. After I got the compiler from MinGW and also installed the Microsoft Visual C++ Compiler for Python, I still cannot install the module because there came new errors. That is when I found there is pymc module listed in anaconda environment that I can add manually, but it showed this conflict error.

I do not know whether the conflict comes from all those other stuff I installed above or not. Please HELP! Thanks!

      Create a new conda environment for Python 2.7:

      conda create -n my_pymc_env python=2.7

      Activate it:

      conda activate my_pymc_env

      Alternatively, for older conda versions on Windows:

      activate my_pymc_env

      on Unix (including Mac OS X):

      source activate my_pymc_env

      Once activated, install your packages:

      conda install pymc blaze

      If you still get this message, install the Anaconda client:

      conda install anaconda-client

      and search for your package:

      anaconda search mypackage

      Look for a channel that has the right version for you and install:

      conda install -c channel_with_right_version mypackage
