安装ember时遇到问题

Question

npm install -g ember-cli
npm WARN deprecated minimatch@2.0.10: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue
/usr/local/Cellar/node/6.3.1/libexec/npm/bin/ember -> /usr/local/Cellar/node/6.3.1/libexec/npm/lib/node_modules/ember-cli/bin/ember
/usr/local/Cellar/node/6.3.1/libexec/npm/lib
└── ember-cli@2.9.1 

以上是我用来安装ember的命令。但是当我输入ember -v时，它会显示-bash: ember: command not found。

我做错了什么？
