mup MongoDB配置复制失败

Question

使用mup，我遇到了无法复制MongoDB配置的问题。

任务列表：

[example.com] - Installing Node.js
[example.com] - Installing Node.js: SUCCESS
[example.com] - Installing PhantomJS
[example.com] - Installing PhantomJS: SUCCESS
[example.com] - Setting up Environment
[example.com] - Setting up Environment: SUCCESS
[example.com] - Copying MongoDB configuration
[example.com] x Copying MongoDB configuration: FAILED
        Permission denied

mup.json：

{
  "servers": [
    {
      "host": "example.com",
      "username": "collin"
    }
  ],
  "setupMongo": true,
  "setupNode": true,
  "nodeVersion": "0.10.40",
  "setupPhantom": true,
  "enableUploadProgressBar": true,
  "appName": "Example",
  "app": "/path/to/proper/location,
  "env": {
    "ROOT_URL": "http://example.com"
  },
  "deployCheckWaitTime": 15
}

我已使用visudo调整了collin ALL=(ALL) NOPASSWD: ALL。据我所知，没有出现其他错误。
