Node.js I'；我正试图将phoenix应用程序部署到heroku，但出现NPM错误

我一直在按照官方文档将使用Elixir版本1.3.0的an phoenix 1.2.0应用程序推送到Heroku，但出现以下错误

这是elixir_buildpack.config的内容

elixir_version=1.3.0

关于错误原因的任何提示？

如果要覆盖默认值，请在应用程序的根目录中创建phoenix_static_buildpack.config文件。该文件的语法是bash

如果未指定配置选项，则将使用buildpack的phoenix\u static\u buildpack.config文件中的默认选项

这是一个包含所有可用选项的完整配置文件：

# Clean out cache contents from previous deploys
clean_cache=false

# We can change the filename for the compile script with this option
compile="compile"

# Add the config vars you want to be exported here
config_vars_to_export=(DATABASE_URL)

# We can set the version of Node to use for the app here
node_version=5.3.0

# We can set the version of NPM to use for the app here
npm_version=2.10.1

# We can set the path to phoenix app. E.g. apps/phoenix_app when in umbrella.
phoenix_relative_path=.

这里是完整的

项目缺少package.json和brunch-config.js。添加这些文件解决了这个问题

是你的节点5.3+和npm 3+。你能尝试更新你的节点版本吗？我添加了一个phoenix_static_buildpack.config文件，将节点和npm版本设置为6.0.0和3.8.6，以便它们可以匹配我在开发中使用的版本。但是我得到了相同的错误/我已经有一个错误来设置节点和npm版本。不幸的是，设置其他选项并没有改变任何事情。有人知道是否可以跳过所有前端内容吗？我不提供任何HTML？既然brunch-config.js和package.js位于

/apps

的较低目录中，如何使用伞式应用程序实现这一点？
