错误命令无法执行。。。npm安装

我随后在当前的Debian系统上安装了Phoenix，但无法使其正常工作。当我想创建一个新的Phoenix应用程序时，我得到以下错误：

abc@xyz:~$ mix phoenix.new test10
* creating test10/config/config.exs
[...]
* creating test10/web/views/page_view.ex

Fetch and install dependencies? [Yn] Y
* running npm install && node node_modules/brunch/bin/brunch build
* error command failed to execute, please run the following command 
again after installation: 
"npm install && node node_modules/brunch/bin/brunch build"

[...]

如果然后运行

npm安装

，我会得到以下结果：

abc@xyz:~/test10$ npm install

要解决此问题，我必须做些什么？

运行

mix deps.get

完成了以下操作：

abc@xyz:~/test10$ mix deps.get
Could not find Hex, which is needed to build dependency :phoenix
Shall I install Hex? (if running non-interactively, use: "mix local.hex --force") [Yn] Y
