Question

我正在尝试在我的Sails.js应用程序中设置Winston Loggly。我按照Sails.js - Using A Custom Logger文档设置了我的/config/log.js文件，如下所示：

// Send logs to Loggly using Winston
var winston = require('winston');
require('winston-loggly');

var customLogger = new winston.Logger();
customLogger.add(winston.transports.Loggly, {
    inputToken: MY INPUT TOKEN,
    auth: {
        username: MY USERNAME,
        password: MY PASSWORD
    },
    subdomain: MY SUBDOMAIN,
    level: 'info',
    tags: ['web-service', process.env.NODE_ENV],
    json: true
});

module.exports.log = {

    level: 'info',
    custom: customLogger,

    // Disable captain's log so it doesn't prefix or stringify our meta data.
    inspect: false

};

无论我做什么，我的控制台都会出现以下错误：

/Users/Nag/Code/web-service/node_modules/winston-loggly/node_modules/loggly/lib/loggly/client.js:190
    return isSolid.test(tag) && tag.length <= 64;
                                   ^

我似乎无法解决这个问题。我该如何解决？

错误似乎指出，由于某种原因，您的 process.env.NODE_ENV 为空，空或未定义。你能检查一下吗？
