在 Heroku 中设置 Python Conda 环境

问：

背景

我在我的项目目录中创建了一个 heroku 实例，使用此处的 conda 环境指南：conda-buildpack

错误

sterlingbutters$ git push heroku master
Counting objects: 7, done.
Delta compression using up to 8 threads.

To https://git.heroku.com/openmc-dash-interface.git
 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/openmc-dash-interface.git'

关于可能导致错误的原因的任何想法？

其他要求

• 部署 python 应用程序后，我仍然需要添加 conda 通道才能安装特定包。我该怎么做？
• 有些包要求在 conda 上没有兼容版本，只有 PyPI（），在 heroku 中使用 conda 环境会丧失使用 pip 的能力吗？pip

更新：我想我弄清楚了我的附加要求和内容：environment.yml

name: openmc-dash-interface
channels:
    - conda-forge
dependencies:
- python=3.6
- anaconda
- openmc
- pip
- pip:
  - dash
  - plotly
  - dash-core-components
  - dash-html-components
  - dash-daq
  - numpy
  - pandas
  - gunicorn

但在构建时仍然出现错误

提前感谢您的任何/所有帮助
