这是我的包.json {“name”：“application”，“version”：“0.0.2”，“private”：“true”，“scripts”：{“start”：“node ./bin/www” }，“dependencies”：{“bcrypt-nodejs”：“0.0.3”，“body-parser”：“~1.13.2”，“connect-flash”：“^ 0.1.1”，“connect-mongo” ：“^ 1.3.2”，“cookie-parser”：“~1.3.5”，“csurf”：“^ 1.9.0”，“debug”：“~2.2.0”，“express”：“^ 4.13 .4“，”express-handlebars“：”^ 3.0.0“，”express-session“：”^ 1.14.2“，”express-validator“：”^ 3.1.1“，”hbs“：”~3.1 .0“，”mongodb“：”^ 2.2.17“，”mongoose“：”^ 4.7.4“，”morgan“：”~1.6.1“，”node“：”0.0.0“，”nodemon“ ：“^ 1.11.0”，“护照”：“^ 0.3.2”，“护照本地”：“^ 1.0.0”，“serve-favicon”：“~2.3.0”，“会话”：“ ^ 0.1.0“，”stripe“：”^ 4.14.0“}}
和Procfile web：node ./bin/www
我尝试了Heroku重启并得到了这个：var bson = new BSON（[BSON.Binary，BSON.Code，BSON.DBRef，BSON.Decimal128，TypeError：BSON不是构造函数）
无法弄清楚为什么它不会部署，提前感谢！
