python - 如何将 ExecJS 使用的 Engine 设置为 NodeJS？

Question

我正在尝试使用以下软件包：https : //github.com/Anorov/cloudflare-scrape/blob/master/cfscrape/init .py

我有以下测试文件：

import cfscrape
import sys
import execjs

who = sys.argv[1]
scraper = cfscrape.create_scraper() 
print scraper.get(who).content

输出以下错误：

Traceback (most recent call last): File "test.py", line 1, in import cfscrape File "build/bdist.macosx-10.10-intel/egg/cfscrape/__init__.py", line 17, in EnvironmentError: Your Javascript runtime 'JavaScriptCore' is not supported due to security concerns. Please use Node.js, V8, or PyV8.

谁能指出我正确的方向将我的 JS_ENGINE 从更改JavaScriptCore为NodeJs
