酶和摩卡咖啡让我在伊斯坦布尔覆盖率测试中出错，为什么？

我有一个ReactJs项目，并且正在使用Enzyme和Mocha进行单元测试。我设置了package.json以执行以下命令：

./node_modules/.bin/mocha 
  --compilers js:babel-register 
  --require 'app/tests/support/setup.mocha.js' 
  --recursive 'app/tests/**/*.test.js'

我想要一份覆盖率报告，所以我决定去伊斯坦布尔。我安装了它，据我了解，这是基本命令

istanbul cover _mocha

但在执行我的coverage脚本时出现错误，如下所示：

./node_modules/.bin/istanbul cover   
  ./node_modules/.bin/_mocha
  --compilers js:babel-register 
  --require 'app/tests/support/setup.mocha.js' 
  --recursive 'app/tests/**/*.test.js'

我有以下错误：

/node_modules/mocha/lib/utils.js:634抛出新错误（“无法解析路径（或模式）'“ +路径+”'“））；

错误：无法在/ node_modules / mocha / bin / _mocha：327：30处的Object.lookupFiles（/node_modules/mocha/lib/utils.js:634:15）处解析路径（或模式）“ js：babel-register” Object的Array.forEach（本机）。（/ node_modules / mocha / bin / _mocha：326：6）在Object.Module的Module._compile（module.js：409：26）在Object.Module._extensions..js（module.js：416：10）。 _extensions。（匿名函数）[作为.js]（/node_modules/istanbul/lib/hook.js:109:37）在Function.Module._load（module.js）处的Module.load（module.js：343：32） ：300：12）在run.fn（/node_modules/istanbul/lib/command/common/run-with-cover.js:122:16）在Function.Module.runMain（module.js：441：10）在/ node_modules / istanbul / lib / command / common / run-with-cover.js：251：17 /node_modules/istanbul/lib/util/file-matcher.js:68:16 at / node_modules / istanbul / node_modules / async / lib / async.js：52：

这是文件结构，我的脚本是从/ web /文件夹执行的

这是package.json
