conda skeleton followed by cond build looks successful but cannot import package

[josh....@gmail.com]

I wanted to install a few packages into my Anaconda distribution and followed the recipe of

conda skeleton pypi <package name>
conda build <package name>

This worked for the requests package but not when installing bottle,  brewer2mpl and prettyplotlib. What I mean is that for requests I can import the package and use it. When trying to import brewer2mpl I get

ImportError: No module named brewer2mpl

But, there is no indication to me that anything went badly with conda during the build process. Below is the session information, but I have two questions:

1. Did I miss something in the console output below that should have clued me in that the conda skeleton --> conda build process did not work? Everything seems fine...
   
2. Is the conda skeleton --> conda build process the right way to be installing and managing packages that do not ship with Anaconda by default?

Note that if I try

$ conda update brewer2mpl

I get

          Error: package 'brewer2mpl' is not installed in /apps/anaconda

so it is not just an issue with import.

If I try 

conda install brewer2mpl

everything works as expected, but then the package is not tracked by conda.

Thanks,

Josh

Hi Josh, 

The output log looks good.     Did you know you can replace using conda skeleteon followed by conda build with: 

conda build --build-recipe <package name> 

The recipe will be written to <anaconda root>/conda-recipes/<package name>  where it can be modified and then you can run 

conda build <anaconda root>/conda-recipes/<package name>

You can also move this recipe to any directory you like and run conda build on that directory name.   

Then, I didn't understand the conda install brewer2mpl question you asked at the end. 

After you have built the conda package you have to install it by pointing to the *built package* itself.   If you just try to install by the name it will look at your conda repo channels in your .condarc file and then if it doesn't find it there it will try to install it via pip (assuming you have pip installed in your environment). 

so, you should type: 

conda install <anaconda root>/conda-bld/<platform>/<package name>.tar.bz2

in your case it was

conda install /apps/anaconda/conda-bld/linux-64/brewer2mpl-1.3.2-py27_0.tar.bz2

This worked for me on my system for brewer2mpl once I modified the default recipe meta.yaml file to remove a blank line in the imports section of the test section and a redundant import in the same section.

Best,

-Travis

Thanks Travis. Looks like user error on my part so let me try again later today, following your advice. Much appreciated!

Wrapping up this thread... I posted my experience following Travis's advice on the Stackoverflow question where I originally saw the suggestion to do

conda skeleton pypi <package name>
conda build <package name>

In short, everything works great! You can find my Stackoverflow answer here.

Thanks again,

Josh
