Brunch installed with phoenix app doesn't work

问题:

I have created Phoenix 1.0.4 (Elixir) application. After I had added some logic in application I wanted to switch my work for front-end part. On page http://www.jonathanbirkholz.com/how-to-use-font-awesome-on-phoenix/ I read that for 3rd assets I should use Bower. Unfortunately with font-awesome or bootstrap-sass from Bower and with command brunch build I always receive:

/.../my_app/node_modules/acorn/dist/acorn.js:1747
  throw err;
  ^

SyntaxError: Unexpected token (2:10)
  at Parser.pp.raise (/.../my_app/node_modules/acorn/dist/acorn.js:1745:13)

I found that problem is caused by acorn - JavaScript library, so I check dependency tree for Node modules:

├─┬ brunch@2.0.4
│ ├─┬ deppack@0.1.5
│ │ └─┬ detective@4.3.1
│ │   ├── acorn@1.2.2

Brunch 2.0.4 (The newest released) use dependencies for old acorn library. There are newer acorn versions, but detective library allows to use acorn 1.x.x versions.z

回答1:

Probably I found what was wrong. Bower must be installed globally and shouldn't exist locally (in node_modules).

回答2:

I had a similar issue.

Try using Node > 5 and NPM 3, clean your cache and install the node_modules again (delete first).
