C9錯誤：爲安全原因禁用了spawn

Question

我按照步驟http://nodebeginner.org並使用C9作爲我的IDE。我得到這個錯誤，當我require child_process：

代碼：

var exec = require("child_process").exec; 

function start(response) { 
    console.log("Request handler 'start' was called."); 

    exec("ls -lah", function (error, stdout, stderr) { 
    response.writeHead(200, {"Content-Type": "text/plain"}); 
    response.write(stdout); 
    response.end(); 
    }); 
} 

function upload(response) { 
    console.log("Request handler 'upload' was called."); 
    response.writeHead(200, {"Content-Type": "text/plain"}); 
    response.write("Hello Upload"); 
    response.end(); 
} 

exports.start = start; 
exports.upload = upload; 

錯誤：

Request handler 'start' was called. 
child_process.js:243 
    var fds = this._internal.spawn(path, 

       ^

任何幫助，將不勝感激。

C9由於安全原因阻止您使用子進程。你將無法在那裏使用子進程，而是在本地嘗試它們。
