python - 在 Heroku 中设置 Python Conda 环境

Question

背景

我使用此处针对 conda 环境的指南在项目目录中创建了一个 heroku 实例: conda-buildpack

错误

sterlingbutters$ git push heroku master
Counting objects: 7, done.
Delta compression using up to 8 threads.
Compressing objects: 100% (7/7), done.

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有什么想法吗？

其他要求

• 部署 python 应用程序后，我仍然需要添加 conda channel 才能安装特定的包。我该怎么做？
• 部分包要求在conda上没有兼容版本，只有PyPI(pip)，在heroku中使用conda环境是否会丧失使用pip的能力？

更新:我想我已经弄清楚了 environment.yml 的附加要求和内容:

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

此构建包似乎不支持 Python3:https://github.com/heroku-python/conda-buildpack/issues/14

但是，存在其他第三方构建包似乎支持 Python3: https://elements.heroku.com/buildpacks/trib3/conda-buildpack https://elements.heroku.com/buildpacks/teamupstart/conda-buildpack

也许:https://github.com/pl31/heroku-buildpack-conda
