node.js - WebStorm 7 - Yeoman Angular 缺少源映射 `Failed to load resource: the server responded with a status of 404 (Not Found)`

Question

使用 WebStorm 7.0.1 运行 yeoman 角度生成器 grunt 服务器会抛出:

在浏览器加载的文件中搜索 .js.map 或 sourceMappingURL 不会返回任何结果，并且在项目源中也不会出现与错误中的这些文件相关的结果。

仅当 WebStorm 连接到 JetBrains IDE 支持插件、初始启动和文件更改实时重新加载时才会显示错误。它们显示在 IDE 的 javascript 调试控制台以及浏览器控制台中，但是一旦打开开发人员工具并从浏览器完成刷新，就不会抛出任何错误(因此我无法检查网络选项卡，除非有办法在新选项卡加载时启动开发人员工具，编辑:实际上这也不起作用)。

重现问题的步骤:

• 安装 yeoman 角度生成器
• 从这些来源创建一个 webstorm 项目
• 使用以下配置启动项目(将为 JS 自动创建第二个配置):

Node interpreter: pathToNode\nodejs\node.exe

Working directory: ProjectRootFolder

JavaScript file: C:\Users\UserName\AppData\Roaming\npm\node_modules\grunt-cli\bin\grunt

Application param: server

对于浏览器/实时编辑:

check After launch

check with JavaScript debugger

start url: http://localhost:9000

关于如何调试这些错误有什么想法吗？感谢您的帮助!

这些消息只是调试输出:Jetbrains IDE Chrome 扩展会检查是否存在 js.map 文件，如果未找到，则打印一条消息。进行此检查的原因是，一些用于压缩/转换代码的工具不会生成调试器定位源映射所需的//sourceMapUrl 注释，因此它会检查一些默认位置是否存在映射。因此，这些消息并不表示任何错误，也不会造成任何伤害，可以安全地忽略它们。此调试输出将在下一个插件更新中被过滤掉 - 修复正在进行中
