Heroku应用程序部署失败，nodejs和flas

Question

我正在使用一个引导模板，在这个模板上我添加了python和flask。当我尝试部署到Heroku时，我得到的是：

我试着编辑我的包.json文件如下所示（在操作系统和arch中添加了强调，因为以前没有。你知道吗

但是，构建仍然失败。你知道吗

关于其他信息，我已经添加了heroku/nodejs和heroku/python buildpacks。 另外，我的目录结构如下所示：

website
--static
    --css
    -- img
    --js
    --node_modules (this is ignored in .gitignore)
    --scss
    --vendor
--templates
    --whole bunch of .html files as well as the gulpfile.js
--website_src
    --bunch of .py files
.gitignore
__init__.py
app.py
environment.yml
package.json
