我试图连接到生产的mlab db和我的本地数据库进行开发。据我可以告诉我的NODE_ENV已设置为生产。但是因为我看不懂，所以我怀疑它是以某种方式搞砸了。另外，我一直连接到我的开发数据库。
我运行我的mongod实例。在另一个cli中，导航到我的应用程序文件夹，该文件夹包含我的app.js文件。我正在遵循一个教程，说运行
process.env.NODE_ENV
但是，我知道这个命令不被识别。所以我检查我的NODE_ENV变量使用：set 我得到NODE_ENV=production，我以前设置。然而。当我使用npm start运行我的应用时，我仍然连接到我的开发服务器。这里是我的db.js code：
var mongoose = require('mongoose');
var gracefulShutdown;
var dbURI = 'mongodb://localhost/Loc8r';
if(process.env.NODE_ENV == 'production'){
console.log('we are in production');
dbURI = 'mongodb://username:[email protected]:55555/dbname'
}
mongoose.connect(dbURI);
// to address mongoose closing issues in windows
var readLine = require('readline');
if (process.platform === "win32"){
var rl = readLine.createInterface({
input: process.stdin,
output: process.stdout
});
rl.on ("SIGINT", function(){
process.emit ("SIGINT");
});
}
// close Mongoose connection, passing in an anonymous function to run when closed
gracefulShutdown = function(msg, callback){
mongoose.connection.close(function(){
console.log("Mongoose disconnected through " + msg);
callback();
});
};
mongoose.connection.on('connected', function(){
console.log('Mongoose connected to ' + dbURI);
});
mongoose.connection.on('error', function(err){
console.log('Mongoose connection error: ' + err);
});
mongoose.connection.on('disconnected', function(){
console.log('Mongoose disconnected');
});
// for nodemon termination
process.once('SIGUSR2', function(){
gracefulShutdown('nodemon restart', function(){
process.kill(process.pid, 'SIGUSR2');
});
});
// for app termination
process.on('SIGINT', function(){
gracefulShutdown('app termination', function(){
process.exit(0);
});
});
// for HEroku termination
process.on('SIGTERM', function(){
gracefulShutdown('Heroku app shutdown', function(){
process.exit(0);
});
});
require('./locations');
不知道从哪里开始寻找。我用尽了我的谷歌搜索。
