以下代码将整个数组保存为redis列表中的单个值.但我想单独保存数组值.我该怎么做？
PS很抱歉英语不好.
var redis = require('redis'),
client = redis.createClient();
var arr = [1,2,3];
client.rpush('testlist',arr);
我是RequireJS的新手,并尝试使用RequireJS加载手柄预编译模板.它加载了把手模板和运行时,但Handlebars运行时未定义.

child.js
console.log('I\'m child');
main.js
var cp = require('child_process');
cp.execFile('./child.js', function (err, stdout,stderr) {
console.log('Err: ',err);
console.log('STDerr: ',stderr);
});
回调中的错误对象是
{ [Error: spawn Unknown system errno 193]
code: 'Unknown system errno 193',
errno: 'Unknown system errno 193',
syscall: 'spawn' }
