ethereumjs-vm的例子有用到这个
看完ethereumjs-vm,再看他ethereumjs/browser-builds,然后最后看他http-server,然后就能了解ethereumjs-vm的例子ethereumjs-vm/examples/run-transactions-simple了

http-server: a command-line http server一个命令行http服务器
http-server
is a simple, zero-configuration command-line http server. It is powerful enough for production usage, but it's simple and hackable enough to be used for testing, local development, and learning.
http-server
是简单的、零配置的命令行http服务器。它足够强大,可以用于生产使用,但是它足够简单和可编程,可以用于测试、本地开发和学习
Installing globally:全局安装
Installation via npm
:
npm install http-server -g
安装的版本:
+ http-server@0.11.1
This will install http-server
globally so that it may be run from the command line.
这将全局安装http-server
,以至于它能从命令行运行
Usage:
http-server [path] [options]
