Yeoman错误，无法访问Yeoman，问题：“错误：找不到模块'cli-width'”

Question

I'm getting errors trying to install yeoman generators. I have previously scaffolded out many projects with yeoman.

I don't know what caused me to get errors, but no yeoman commands work anymore. I can't run yo and I can't scaffold a project out or install any new generators.

Here's a little history of my errors

$ yo angular

module.js:338
    throw err;
          ^
Error: Cannot find module 'through'
    at Function.Module._resolveFilename (module.js:336:15)
    at Function.Module._load (module.js:278:25)
    at Module.require (module.js:365:17)
    at require (module.js:384:17)
    at Object.<anonymous> (/usr/local/lib/node_modules/yo/node_modules/yeoman-environment/node_modules/inquirer/lib/ui/bottom-bar.js:6:15)

    at Function.Module._load (module.js:310:12)
    at Module.require (module.js:365:17)
    at require (module.js:384:17)

Then I installed this 'through' module:

npm install -g through

Ok so it should be all good now right? Wrong,

 $ yo
module.js:338
    throw err;
          ^

I have stopped there, I don't want to go down a worm hole installing npm packages without knowing if I'm on the right path or not. I can't find anything with similar problems so I'm not sure of the root cause that started causing these errors.

I'm on OSX using Mavericks.

Well you didn't provide the command you ran, so it's hard to help... But it's definitively an issue with npm.

But two usual trouble shooting:

1. Never run npm with sudo .
2. Read the npm installation log as it may already have told you what the errors were.
