vs2015加载项目失败

问题汇总

vs2015加载项目失败
HelloWorld.vcxproj : error  : 发生一个或多个错误。

检查步骤

HelloWorld.sln 文件中指定的 HelloWorld.vcxproj 的路径是否正确
HelloWorld.vcxproj 文件中 一些路径是否正确(包括环境变量)
主要是这两个文件有错误

我的问题

MatchVSDemo-Cocos2dx.vcxproj 文件

原因

cmd 下执行 echo %COCOS_FRAMEWORKS%
发现MatchVSDemo-Cocos2dx.vcxproj工程文件中COCOS_FRAMEWORKS变量在系统中没有定义

解决方法

1、装cocos2d-x环境
2、在系统环境变量中加上COCOS_FRAMEWORKS变量

其他

解决方法列的不全，这只是我遇到问题的解决方法之一
