我在尝试将我的 Phoenix 应用程序推送到 Heroku 时遇到此错误。

我一直在关注guide from the Phoenix framework website。

是什么导致了这个错误，我该如何解决？

【问题讨论】：

从输出看来您的节点已更新，而 npm 没有。也许手动更新npm？在这里找到了可能的解决方案：github.com/npm/npm/issues/10165#issuecomment-152451743
我试过这个（在问问题之前找到那个线程）但它没有帮助。不过谢谢你的想法。
你试过使用 sudo 吗？
是的，我也使用 sudo 运行了 hat 命令。

【解决方案1】：

我之前遇到过和你一样的问题。尝试将 npm 版本添加到 phoenix_static_buildpack.config 文件中

这是我的应用中的一个示例：

phoenix_static_buildpack.config（在根目录中）

clean_cache=false
compile="compile"
config_vars_to_export=(DATABASE_URL)
node_version=6.9.5
npm=3.10.8
phoenix_relative_path=.
remove_node=false

您还可以设置 elixir_buildpack.config（也在根目录中）

erlang_version=18.3
elixir_version=1.4.0
always_rebuild=false
runtime_path=/app
