一个解析javascript的模块,虽然支持python3，但是支持的python3支持的引擎貌似有问题啊。

v8是直支持py2.7哎，暂时空架而已

Run JavaScript code from Python.

PyExecJS is a porting of ExecJS from Ruby. PyExecJS automatically picks the best runtime available to evaluate your JavaScript program, then returns the result to you as a Python object.

A short example:

>>> import execjs
>>> execjs.eval("'red yellow blue'.split(' ')")
['red', 'yellow', 'blue']
>>> ctx = execjs.compile("""
...     function add(x, y) {
...         return x + y;
...     }
... """)
>>> ctx.call("add", 1, 2)
3

Of course, you can pick particular JavaScript runtime by get() function:

>>> default = execjs.get() # the automatically picked runtime
>>> default.eval("1 + 2")
3
>>> jscript = execjs.get("JScript")
>>> jscript.eval("1 + 2")
3
>>> node = execjs.get("Node")
>>> node.eval("1 + 2")
3

If EXECJS_RUNTIME environment variable is specified, PyExecJS pick the JavaScript runtime as a default:

>>> #execjs.get().name # this value is depends on your environment.
>>> os.environ["EXECJS_RUNTIME"] = "Node"
>>> execjs.get().name
'Node.js (V8)'

PyExecJS supports these runtimes:
