安装npm软件包时出现TypeError

Question

I'm not very familiar with js-related technologies and now having trouble with package installation. Log file contains these lines:

1469 verbose stack TypeError: Cannot read property '2.2.2' of undefined
1469 verbose stack     at setData (C:\Program Files\nodejs\node_modules\npm\lib\cache\add-named.js:135:27)

1469 verbose stack     at fixName (C:\Program Files\nodejs\node_modules\npm\lib\cache\add-named.js:29:5)

1469 verbose stack     at FSReqWrap.oncomplete (fs.js:82:15)

and unfortunately it tells me absolutely nothing. Haven't even a slight idea where to dig in for resolution. Maybe someone could guide?

Answer 1

Check package.json file in the root of your project and mark the dependency with version number 2.2.2 as *

 "dependencies": {
    "express": "*",
    "mongodb": "*",
    "underscore": "*",
  }

like this. then run npm install again.
