我正在学习快递,我正在运行此代码:
var express = require('express');
var app = express();
var port = process.env.PORT || 3000;
app.get('/', function(req, res) {
res.send('<html><head></head><body><h1>Hello World!</h1></body></html>');
});
app.get('/api', function(req,res) {
res.json({ firstname: 'John', lastname: 'Doe'})
});
app.listen(port);
当我尝试像这样执行它时,它可以工作:
node app.js
但是当我尝试以这种方式运行时:
nodemon app.js
发生这种情况:
[nodemon] 1.8.1
[nodemon] to restart at any time, enter `rs`
[nodemon] watching: *.*
[nodemon] starting `node app.js`
events.js:141
throw er; // Unhandled 'error' event
^
Error: spawn cmd ENOENT

at onErrorNT (internal/child_process.js:344:16)
at doNTCallback2 (node.js:441:9)
at process._tickCallback (node.js:355:17)
似乎有什么问题?

请重新启动计算机并再次尝试。 就我而言,它有所帮助。
