resolving package resolutions in conda

Question

Time and again, I'm faced with this disturbing problem of warning: possible package resolutions (only showing differing packages):

For instance:

junk ? conda update --all
Solving environment: - 
Warning: >10 possible package resolutions (only showing differing packages):
  - anaconda::cymem-1.31.2-py36_0, anaconda::plac-0.9.6-py36_0, anaconda::preshed-1.0.0-py36_0, conda-forge::joblib-0.11-py36_0
  - anaconda::cymem-1.31.2-py36_0, anaconda::plac-0.9.6-py36_0, anaconda::preshed-1.0.0-py36_0, defaults::joblib-0.11-py36_0
  - anaconda::cymem-1.31.2-py36_0, anaconda::preshed-1.0.0-py36_0, conda-forge::joblib-0.11-py36_0, defaults::plac-0.9.6-py36_0
  - anaconda::cymem-1.31.2-py36_0, anaconda::preshed-1.0.0-py36_0, defaults::joblib-0.11-py36_0, defaults::plac-0.9.6-py36_0
  - anaconda::preshed-1.0.0-py36_0, conda-forge::joblib-0.11-py36_0, defaults::cymem-1.31.2-py36_0, defaults::plac-0.9.6-py36_0
  - anaconda::preshed-1.0.0-py36_0, defaults::cymem-1.31.2-py36_0, defaults::joblib-0.11-py36_0, defaults::plac-0.9.6-py36_0
  - anaconda::plac-0.9.6-py36_0, anaconda::preshed-1.0.0-py36_0, conda-forge::joblib-0.11-py36_0, defaults::cymem-1.31.2-py36_0
  - anaconda::plac-0.9.6-py36_0, anaconda::preshed-1.0.0-py36_0, defaults::cymem-1.31.2-py36_0, defaults::joblib-0.11-py36_0
  - anaconda::plac-0.9.6-py36_0, conda-forge::joblib-0.11-py36_0, defaults::cymem-1.31.2-py36_0, defaults::preshed-1.0.0-py36_0
  - anaconda::cymem-1.31.2-py36_0, anaconda::plac-0.9.6-py36_0, conda-forge::joblib-0.11-py36_0, defaults::preshed-1.0.0-py36_0
  ... and othedone

How do I resolve these warnings? Is it possible to suppress it? Completely resolving it would definitely be nicer than suppressing it.

I have already tried doing:

$ conda update conda

But, unfortunately, that didn't solve the issue as claimed in: conda/issues/1580

您可以使用以下命令解决了我的问题

conda update --strict-channel-priority --all

基本上，此命令强制更新所有警告包。
