【问题描述】：
我安装了 nodebrew、yeoman 和 2 个生成器（generator-webapp、generator-bootstrap）。但是 yeoman 似乎不知道生成器：
$ yo webapp
Error webapp
You don't seem to have a generator with the name webapp installed.
You can see available generators with npm search yeoman-generator and then install them with npm install [name].
To see the 3 registered generators run yo with the `--help` option.
（当为yo bootstrap时，也会出现类似的错误。）
所以我运行yo --help，但它没有显示任何生成器：
$ yo --help
Usage: yo GENERATOR [args] [options]
General options:
-h, --help # Print generator's options and usage
-f, --force # Overwrite files that already exist
但是我运行yo 没有参数，生成器显示：
$ yo
? 'Allo mehtats! What would you like to do? (Use arrow keys)
Run a generator
❯ Bootstrap
Webapp
Mocha
──────────────
Update your generators
Install a generator
Find some help
Get me out of here!
──────────────
然后我选择Webapp运行这个生成器，出现错误：
Make sure you are in the directory you want to scaffold into.
This generator can also be run with: yo webapp

Out of the box I include HTML5 Boilerplate, jQuery, and a Gruntfile.js to build your app.
? What more would you like? Bootstrap
create Gruntfile.js
create package.json
create .gitignore
create .gitattributes
create .bowerrc
create bower.json
create .jshintrc
create .editorconfig
create app/styles/main.css
create app/favicon.ico
create app/robots.txt
create app/index.html
create app/scripts/main.js
Error
You don't seem to have a generator with the name mocha installed.

我参考了其他问题并做了npm install --force -g webapp，但没有解决。
yo doctor 说：
$ yo doctor
[Yeoman Doctor] Everything looks all right!
版本：
$ yo -v
1.4.0
$ node -v
v0.11.14
