我已成功安装 node.js。我已经创建了文件
var http = require('http');
var url=require('url');
var fs=require('fs');
var io = require('socket.io');
http.createServer(function (req, res) {
fs.readFile('/var/www/nodeJS/client.html' ,
function ( err, data ) {
if ( err ) {
console.log( err );
res.writeHead(500);
return res.end( 'Error loading client.html' );
}
res.writeHead( 200 );
res.end( data );
});
}).listen(8124, '127.0.0.1');
io.listen(http);
io.sockets.on('connection', function (socket) {
socket.emit('news', { hello: 'world' });
socket.on('my other event', function (data) {
console.log(data);
});
});
每当我使用 io 对象时都会发生错误。没有 io 它工作正常。
Error: Cannot find module 'zeparser'

在此之后,我还单独安装了模块 zeparser。我的默认 npm 安装目录似乎是 /usr/local/lib/node_modules。
我已将 NODE_PATH 设置为
export NODE_PATH="/usr/local/lib/node_modules"
但得到同样的错误。
然后我尝试将 zeparser 模块复制到 /var/www/nodeJS/node_modules。然后错误变为
/var/www/nodeJS/node_modules/socket.io/lib/manager.js:104
server.on('error', function(err) {
