node.js - 错误!错误 : EPERM,

Question

如果尝试在 USB 设备上构建 node.js 应用程序时在我的树莓派上使用 npm 时遇到一些问题。

package.json 看起来像这样:

{
  "name" : "node-todo",
  "version" : "1.0.0",
  "description" : "TodoApp",
  "main" : "server.js",
  "autho" : "Stephan",
  "dependencies" : {
     "express" : "*"
  }
}

使用 npm install 结果:

npm WARN package.json node-todo@1.0.0 No repository field.
npm WARN package.json node-todo@1.0.0 No README data

如果我尝试在/home/myUser/Appfolder 中运行 npm install 一切正常。ServerHD 上的所有文件均由主文件夹所属的同一用户创建。我尝试使用:

1. npm install -no-bin-links 导致同样的问题
2. 尝试将 ServerHD 上的文件夹更改为 777 对 npm 没有影响
3. 尝试使用 sudo 运行 npm install

使用 express-generator 会导致类似的问题。

希望有人能帮忙。到目前为止谢谢。
