我正在尝试学习如何使用node.js，并且我已经开始使用this tutorial了。当我直接用node app.js启动节点时，一切正常。当我使用pm2 start app.js在PM2下运行节点作为服务时，一切也正常。
但是，如果我在使用pm2 start app.js --watch更改文件时尝试让PM2自动重启我的节点应用程序，它会停止正确提供我的CSS，并且 ERR_EMPTY_RESPONSE 在Chrome中尝试查看CSS文件的路径时。
PM2错误日志为空。输出日志仅记录网站根目录的GET请求，并带有304响应代码。如果我直接使用节点，则控制台会为根记录200响应，对第一页加载的style.css执行200响应，对同一个nod会话的每个后续页面加载执行304响应。
我已尝试使用processes.json中详细说明使用// ./app.js
var express = require('express'),
stylus = require('stylus),
nib = require('nib'),
app = express();
function compile(str, path) {
return stylus(str).set('filename', path).use(nib());
}
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.use(express.logger('dev'));
app.use(stylus.middleware({ src: __dirname + '/public', compile: compile }));
app.use(express.static(__dirname + '/public'));
app.get('/', function(req, res) {
res.render('index', { title: 'My Title' });
});
app.listen(3000);
准确指定要使用PM2观看哪些文件，但它似乎不会影响结果。
