Installing on osx-64 installs in anaconda 4 root environment old versions due to dependencies

[Erik Kretschmer]

A clean install on osx-64 bit fails due to dependencies, more precisely install a deprecated version of mss.

With a clean/new install of anadaconda2:

conda config --add channels conda-forge
conda config --add channels defaults
conda install mss

installs mss 1.2.2:

$ conda list
...
mss                       1.2.2                    py27_0    conda-forge
...

Attempting to force the installation of 1.6.2 leads to UnsatisfiableError:

$ conda install mss=1.6.2
Fetching package metadata .............
Solving package specifications: .

UnsatisfiableError: The following specifications were found to be in conflict:
  - mss 1.6.2* -> pyqt 4.11.* -> qt >=4.8.6,<5.0
  - mss 1.6.2* -> pyqt 4.11.* -> sip >=4.16.4,<4.18
  - navigator-updater
Use "conda info <package>" to see the dependencies for each package.

Hi @geogob

The feedstock on conda-forge

forces:
    - pyqt 4.11.*  # [osx]
    - qt 4.8.*  # [osx]

e.g. OSX Version on conda-forge:

• https://anaconda.org/conda-forge/qt/4.8.7/download/osx-64/qt-4.8.7-7.tar.bz2
• https://anaconda.org/conda-forge/pyqt/4.11.4/download/osx-64/pyqt-4.11.4-py36_2.tar.bz2

with these settings the CI is able to build our package.

You have installed to the root environment. This means a new / update of package has to fullfill all dependencies of already existing packages. The output shows a mismatch with sip. Because sip requires >=4.16.4,<4.18 mss can't be installaed.

Please try the following:

$ conda create -n mssenv python=2
$ source activate mssenv
$ conda install mss

The environment enables to have seperated release versions of packages and only those packages which are needed for one software.

Installation in a dedicated environment was successful. Some package had to be downgraded.

I look into this on conda-forge at the time we build 1.7.0
