node.js - C9 错误：出于安全原因禁用生成

Question

我正在按照http://nodebeginner.org上的步骤操作并使用 C9 作为我的 IDE。当我requirechild_process 时出现此错误：

代码：

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;

错误：

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

                   ^

任何帮助，将不胜感激。

出于安全原因，C9 会阻止您使用子进程。您将无法在那里使用子进程，而是在本地尝试它们。
