我一直在关注官方文档，将Elixir版本1.3.0的phoenix 1.2.0应用推送到Heroku，但得到以下错误。

这是elixir_buildpack.config

elixir_version=1.3.0 

的内容是什么可能是错误的原因的任何暗示？

Answer 1

项目缺乏的package.json和早午餐config.js。添加这些文件解决了这个问题。

Answer 2

如果您要覆盖默认值，请在应用的根目录中创建phoenix_static_buildpack.config文件。该文件的语法是bash。

如果您未指定配置选项，则将使用buildpack的phoenix_static_buildpack.config文件中的默认选项。

下面是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=.
