Bower安装问题

Question

当使用Bower添加包时，每次我不知道如何解决这个问题时都会收到这个错误消息？

我试着通过执行以下操作来加载font awesome或bower安装

$ bower install --save font-awesome
$ bower install

但是我得到了这个错误：

usr/local/lib/node_modules/bower/lib/node_modules/configstore/index.js:54
                throw err;
                ^
    Error: EACCES: permission denied, open '/Users/brandonpowell/.config/configstore/bower-github.json'
    You don't have access to this file.
