在mybinder.org上，我使用了下面的environment.yml

name: python 3.7.4
channels:
  - conda-forge
dependencies:
  - python=3.7.4
  - appmode=0.7.0
  - pandas=0.25.1
  - matplotlib=3.1.1
  - pip=19.2.3
  - pip:
    - mip==1.8.2

在Heruko上，我有以下requirements.txt

appmode
matplotlib
mip
pandas
voila

requirements.txt有什么问题吗

下面的Procfile

web: voila —-port=$PORT --no-browser one-dimensional-bin-packing.ipynb

下面的runtime.txt

python-3.7.6

Answer 1

我也有同样的问题。通过将--enable_nbextensions=True选项添加到Procfile中的voila命令，成功修复了该问题，因此在您的示例中如下所示：

web: voila —-port=$PORT --no-browser --enable_nbextensions=True one-dimensional-bin-packing.ipynb

在此示例存储库中找到了此修复：https://github.com/voila-dashboards/voila-heroku
