ResolvePackageNotFound: Create env using conda and

I want to create a virtual environment using conda and yml file.

Command:

conda env create -n ex3 -f env.yml

Type ENTER it gives following message:

ResolvePackageNotFound:

 - gst-plugins-base==1.8.0=0
 - dbus==1.10.20=0
 - opencv3==3.2.0=np111py35_0
 - qt==5.6.2=5
 - libxcb==1.12=1
 - libgcc==5.2.0=0
 - gstreamer==1.8.0=0

However, I do have those on my Mac. My MacOS: High Sierra 10.13.3

My env.yml file looks like this:

How to solve this problem?

Well....The stack overflow prompt me to say more details, but I think I describe things clearly, it is sad, stack overflow does not support to upload attachment....

I had same problem and found your question googling for it. It's unacceptable, to leave it unanswered for further googlers, even if you had found solution.

ResolvePackageNotFound error describes all packages not installed yet, but required.

To solve the problem, move them under pip section:

name: ex3
channels:
- menpo
- defaults
dependencies:
  - cairo=1.14.8=0
  - ***
  - another dependencies, except not found ones
  - pip:
    - gst-plugins-base==1.8.0                
    - bleach==1.5.0
    - enum34==1.1.6
    - html5lib==0.9999999
    - markdown==2.6.11
    - protobuf==3.5.1
    - tensorflow==1.4.1
    - tensorflow-tensorboard==0.4.0
    - werkzeug==0.14.1
    *** added ***
    - gst-plugins-base==1.8.0
    - dbus==1.10.20
    - opencv3==3.2.0
    - qt==5.6.2
    - libxcb==1.12
    - libgcc==5.2.0
    - gstreamer==1.8.0
