I recently switched to the Anaconda Python distribution and I'm trying to get the hang of things. I wanted to install this yaml-related package and since there isn't already a conda recipe for it, I tried

conda pipbuild layered-yaml-attrdict-config

which resulted in the following output (I removed non-relevant entries of my system path):

C:\Anaconda>conda install layered-yaml-attrdict-config

C:\Anaconda>

I'm not sure what happened since I don't know what file it was looking for and I don't yet know anything about conda recipes except they're supposed to be awesome and not give these kinda of errors.

I was hoping to install through conda so that everything could be managed by conda instead of some stuff being managed by pip.

Digging into the main_pipbuild.py source it looks like it's trying to run C:\Anaconda\envs\_pipbuild_\bin\pip install package==version (with the appropriate package and version). When I look at my C:\Anaconda\envs_pipbuild_ there is no bin folder, so I'm guessing pip didn't get installed into the pipbuild environment correctly. The previous warnings about not having "patch" may also be a problem...

After installing patch with conda install patch I tried again with the following results:

So it finds some kind of problem with the package perhaps at Solving package specifications: .69 unparsed bytes left at the end of stream. Then it does this patch thing which apparently fails. Then it tries to do pip install and again can't find the bin/pip directory in the pipbuild environment.

Should it be looking for pip at C:\Anaconda\envs\_pipbuild_\Scripts\pip.exe? Because that does exist.

If this is a bug, here's where to report it: https://github.com/conda/conda-build/issues. I'll wait for feedback before doing any more.

Any help would be great!

I've had similar issues when trying to build PyPI packages with "conda pipbuild package-name", and I wasn't able to get it running on Windows 7 (x64). One useful workaround that I've found (if you want to install the package with "conda install package-name", into a specific conda environment) is as follows:

  • Install the PyPI package with "pip install package-name"
  • Upload the package to your binstar account with "binstar upload %conda_install_path%/pkgs/package-name-ver-py27.tar.bz2"
  • Install the package into a specific conda env with "conda install -c https://conda.binstar.org/user-name package-name -p %path-to-conda-env%"

There is a fix for the same issue on Python 3 at https://groups.google.com/a/continuum.io/d/msg/anaconda/6_reeaIjx5c/fhRjbA4AdQkJ. It involves editing the distutils\cygwinccompiler.py file in the Python standard library.

I think you can do the same thing in Python 2, though it may require some translation, as the Python 2 version of cygwinccompiler uses os.popen instead of subprocess.check_output. Assumedly you can just use subprocess.check_output(['gcc', '-dumpmachine'], shell=True) in the relevant place in the file and it will fix the issue.
