为什么 Mocha.js 找不到模块？

Question

我不明白为什么 mocha.js 找不到我的路径！这是我在节点课程项目中包含的文件结构

  ///////Root
  --package.json
  --node_modules/
  --playground
  --server
     -server.js
     -db
     -models
     -tests
           ---server.test.js

每次我运行 "mocha server/**/*.test.js" 在从命令提示符运行执行测试命令后，我从命令提示符得到这个错误：

    > todo-api@1.0.0 test C:\Users\Omar Ali\Desktop\node-todo-api
> mocha server/**/*.test.js

module.js:549
    throw err;
    ^

感谢您展示结构，它应该是 ../server 或 ../server.js，因为您的 server 模块（或文件）位于测试脚本。
