I've built a package through conda-build. When I'm installing it through conda install --use-local PACKAGENAME it works perfectly. Afterwards, I'm uploading the package to anaconda.org through anaconda upload PATH. But when I'm trying to install the package from anaconda.org, it doesn't work. It installs without errors, but I can't import the package and I can't use the related CLI. What could be the reason for this?

Here is my meta.yaml, which I used to built the package:

{% set name = "packagename" %}
{% set version = "1.0.0" %}

package:
  name: "{{ name|lower }}"
  version: "{{ version }}"

source:
  url: "https://test.pypi.io/packages/source/{{ name[0] }}/{{ name }}/{{ name }}-{{ version }}.tar.gz"

  script: "{{ PYTHON }} -m pip install ."

requirements:
