我正在尝试按照本教程Testing in Node.js使用以下命令安装mocha
sudo npm install -g mocha
得到以下回复：
npm WARN deprecated has-color@0.1.7: Renamed to supports-color. If you're using chalk, upgrade to the latest version. https://github.com/chalk/supports-color

但是在我的项目目录中运行mocha不会产生任何响应：
lingxiao@computer:~/dir/to/proj$ find *

有谁知道问题是什么？
