Blockly 版本选择
在【兰州大学】Blockly创意趣味编程【全36讲】主讲教师：崔向平 周庆国中提到，在18年6月份之前的版本中，可以通过安装依赖库的方式，打开开发者工具的离线版本，但是新版本的Blockly移除了部分离线的依赖文件。
在Github仓库上，对于18年6月份之前的版本，我只找到了2017.10.23的版本是相对较新的blockly-update-20171023，可配套Closure Library v20180405使用开发者工具
但是这个版本的Blocks是有问题的：
这里搜集存档了一份整合修改过的版本：Blockly积木编程离线整合包
上手
参考 Blockly 中文文档 及 ./blockly/demos/code/index.html 文件，建立自己的工程文件demo.html
