无法创建anaconda环境ResolvePackageNotFound

Question

I've been trying to use this yml file to create an environment (I created the yml):

name: testenv
channels:
- esri
- scitools
- obspy
- conda-forge
- defaults
dependencies:
- appnope=0.1.0=py36_0
- libgfortran=3.0.0=0
- pip=9.0.1=py36_0
- python=3.6.2=0
- wheel=0.30.0=py_1
- pip:
  - ipython-genutils==0.2.0
  - jupyter-client==5.1.0
  - jupyter-console==5.1.0
  - jupyter-core==4.3.0
  - prompt-toolkit==1.0.15

however it always fails with the following error message:

Using Anaconda API: https://api.anaconda.org
Solving environment: failed

ResolvePackageNotFound:
  - wheel==0.30.0=py_1
  - appnope==0.1.0=py36_0

Is it searching the wrong channels for it? I can find these packages if I simply install them in the base conda install. Thanks for your help.

Answer 1

The problem is that the Anaconda isn't lying to me. Those packages don't exist in the linux channels however they do exist in the OSX channels. So it is a platform specific problem.

Answer 2

Had this same issue. Solved it by removing both the build versions AND package version (except for necessary package versions such as python=3.6.2 and any others.) The end yml file would look like this in order to be fully cross-platform:

name: testenv
channels:
- esri
- scitools
- obspy
- conda-forge
- defaults
dependencies:
- appnope
- libgfortran
- pip
- python=3.6.2
- wheel
- pip:
  - ipython-genutils
  - jupyter-client==5.1.0
  - jupyter-console
  - jupyter-core
  - prompt-toolkit
