Problems with python 3.6 and removing local builds

[deep tavker]

Hello, I’m new to open source development. I’m facing some problems. This mail is in markdown format (please lemme know if I should avoid this in future. I'll rewrite these issues in normal format if need be.)

Problem 1

I’ve been working on a conda recipe for the pysph module. The problem I’m facing currently is that when I build the recipe for pysph and install it, the files are copied into lib/python3.6/site-packages and not lib/python3.5/site-packages (which I want) .

Here’s what I did:

deep@deep-Lenovo-G50-80:~/condarecipe/PySPH_Project$ conda build --python=3.5 pysph
BUILD START: pysph-1.0a4-py35_0
updating index in: /home/deep/miniconda3/conda-bld/linux-64
updating index in: /home/deep/miniconda3/conda-bld/noarch

...
#lines (will print specific ones if you ask)
...

TEST END: /home/deep/miniconda3/conda-bld/linux-64/pysph-1.0a4-py35_0.tar.bz2
INFO conda_build.config:__exit__(422): --dirty flag not specified.  Removing build folder after successful build/test.

# If you want to upload package(s) to anaconda.org later, type:

anaconda upload /home/deep/miniconda3/conda-bld/linux-64/pysph-1.0a4-py35_0.tar.bz2

# To have conda build upload to anaconda.org automatically, use
# $ conda config --set anaconda_upload yes

anaconda_upload is not set.  Not uploading wheels: []

deep@deep-Lenovo-G50-80:~/condarecipe/PySPH_Project$ anaconda upload /home/deep/miniconda3/conda-bld/linux-64/pysph-1.0a4-py35_0.tar.bz2

deep@deep-Lenovo-G50-80:~/condarecipe/PySPH_Project$ conda install -c tavkerdeep pysph

This copies the module into ~/miniconda3/lib/python3.6/site-packages and not ~/miniconda3/lib/python3.5/site-packages

Here’s the error message

deep@deep-Lenovo-G50-80:~$ pysph test

Problem 2

Can’t clear local builds for specific packages.

deep@deep-Lenovo-G50-80:~/miniconda3/conda-bld/linux-64$ conda install --use-local pysph
Fetching package metadata ...........
Solving package specifications: .
Warning: 2 possible package resolutions (only showing differing packages):
  - local::pysph-1.0a4-0
  - local::pysph-1.0a4-py35_0

Package plan for installation in environment /home/deep/miniconda3:

The following NEW packages will be INSTALLED:

    pysph: 1.0a4-0 local

Proceed ([y]/n)? n

Exiting

As one can see, there are two possible package resolutions. I need to get rid of one of them or both of them. I tried to delete the tarfile for one of them and updating the index using conda index but it didn’t help. I was about to edit repodata.json but after skimming through the forums, I avoided it.

deep@deep-Lenovo-G50-80:~$ cd ~/miniconda3/conda-bld/linux-64/
deep@deep-Lenovo-G50-80:~/miniconda3/conda-bld/linux-64$ ls
pyinstrument                        pysph-1.0a4-0.tar.bz2       repodata.json      toolz-0.6.0-py35_0.tar.bz2

deep@deep-Lenovo-G50-80:~/miniconda3/conda-bld/linux-64$ conda remove pysph

    pysph: 1.0a4-py35_0 local

So how to make sure that there is only one possible package resolution? (Or is there any way to choose which to install ? )

Any help would be much appreciated. Thank you
