在 nodejs 中运行 mocha 测试的问题

Question

I'm getting the following error while running "npm run test":

And my package.json is as follows:

{
 "name": "express-app",
 "version": "1.0.0",
 "private": true,
 "scripts": {
   "start": "node ./bin/www",
   "test": "nyc --reporter=lcov mocha ./tests/unitTests --color",
   "integrationTest": "mocha ./tests/integrationTests --exit"
},
 "dependencies": {
  "cookie-parser": "1.4.3",
  "cors": "^2.8.5",
  "debug": "2.6.9",
  "ejs": "2.5.9",
  "express": "4.16.3",
  "express-mung": "0.5.1",
  "express-validation": "^3.0.2",
  "http-errors": "1.6.3",
  "mongoose": "^5.9.7",
  "prom-client": "11.3.0",
  "swagger-ui-express": "4.0.4"
  },
 "devDependencies": {
   "chai": "4.2.0",
   "chai-http": "4.3.0",
   "mocha": "6.1.4",
   "nyc": "14.1.1"
  }
}

I have tried installing mocha globally using the command:

npm i -g mocha  

Even after which I'm getting the above same error. Can anyone please let me know what Im doing wrong?

UPDATE:
My machine is behind a corporate proxy

This seems like a problem with nyc itself. Try updating to the version suggested in this github issue: https://github.com/istanbuljs/nyc/issues/1205 .
