问题解答
回答1：搞定了，这个bug可以分两个部分来看，Failed to load c++ bson extension, using pure JS version，这部分需要npm install node-gyp -g 有时死活下不下来有时分分钟下好了；接着你需要开启mongodb数据库,命令行路径开到mongodb的bin下面手动设置你要的项目数据库路径 mongod.exe --dbpath c:datablog然后在项目的package.json里面
'mongodb':'latest','express-session':'latest','connect-mongo':'latest','mongoose':'latest'
把这几个版本安装成最新的，不然还是会报错再启动大功告成啦~~~
