我正在努力按照https://www.npmjs.com/package/generator-mean-seed
当我尝试运行"sudo npm install-g generator mean seed"时，我得到了这个错误
npm install -g generator-mean-seed

npm WARN generator-mean-seed@1.1.26 requires a peer of yo@>=1.0.0 but none was installed.
它说我需要安装版本>1.0.0的yo，但我已经安装了
yo --version
1.6.0
你知道我做错了什么吗？或者有什么线索可以解决这个问题吗？
我遇到了同样的问题。。。原因似乎是在后来的npm版本中，对等依赖关系的安装发生了变化。作为一种变通方法，在安装generator-mean-seed时包括yo（它已经安装也没关系）：
$ sudo npm install -g yo generator-mean-seed
这样，生成器意味着种子将正确安装：
$ sudo npm install -g yo generator-mean-seed
