在使用cocos2dx进行C++到Lua的绑定过程中，可能会遇到PYTHON_BIN未定义的问题，需要根据cocos2d-x的官方文档配置环境变量。此外，如果安装PyYAML时遇到Python 2.7未在注册表中找到的问题，可以通过创建并运行register.py文件来解决，确保Python 2.7已成功注册。

A.运行genbindings.py出现PYTHON_BIN not defined, use current python.

解决方案：

cocos2dx C++ 绑定到 Lua时，运行genbindings.py出现PYTHON_BIN not defined, use current python.请参照

cocos2dx3.0rc导出自定义类到lua的方法详细步骤一文中安装第一要点：

1、安装必要的库和工具包，以及配置相关环境变量，请按照cocos2d-x-3.0rc0\tools\tolua\README.mdown说得去做，不做赘述。文档里阐述了主要系统平台绑定的前提条件

B.安装PyYAML-3.10出现：Python version 2.7 required,which was not found in registry.

解决方案:不能在注册表中识别出来python2.7

方法：新建一个register.py 文件，把一下代码贴进去，保存

cmd下运行python register.py 显示“python 2.7 is already registered”表示成功，PyYAML可以成功继续安装，完成

代码如下：

            print "*** Unable to register!"
            return
        print "--- Python", version, "is now registered!"
        return
    if (QueryValue(reg, installkey) == installpath and
        QueryValue(reg, pythonkey) == pythonpath):
        CloseKey(reg)
        print "=== Python", version, "is already registered!"
        return
    CloseKey(reg)
    print "*** Unable to register!"
    print "*** You probably have another Python installation!"
 
if __name__ == "__main__":
    RegisterPy()
