express-node测试覆盖率w lib/mocha错误: ENOENT:没有这样的文件或目录node_modules/ such report/lib/html/assets

Question

使用

"babel-cli": "6.18.0",
"babel-core": "6.18.0",
"babel-plugin-add-module-exports": "0.2.1",
"babel-preset-es2015": "6.16.0",
"babel-preset-stage-2": "6.18.0",

"coveralls": "^2.13.0",
"istanbul": "1.1.0-alpha.1",
"mocha": "3.2.0",

当我运行脚本时

 "test:coverage": "cross-env NODE_ENV=test ./node_modules/.bin/istanbul cover _mocha -- --ui bdd --reporter spec --colors --compilers js:babel-core/register server/tests --recursive"

所有测试都通过了

    ...
15 passing (904ms)

但我从伊斯坦布尔-报告模块得到一个错误，欢迎任何提示...

fs.js:871
  return binding.readdir(pathModule._makeLong(path), options.encoding);
                 ^

解决..。

我的脚本中缺少伊斯坦布尔的--report选项！

"test:coverage": "cross-env NODE_ENV=test ./node_modules/.bin/istanbul cover 
 --report lcov --report json --report text --report html _mocha -- --ui bdd 
--reporter spec --colors --compilers js:babel-core/register server/tests --recursive",
