在安装Yeoman遇到了一些报错，具体的步骤就不多说了，直接上码,具体的两处报错的地方。
第一个，创建webapp，直接报权限的错误，这时才留意到在它之前还有一个错误。
[root@iZ289zd8c52Z yeomanapp]# yo webapp

前一个错误，再安装yeoman时，报的错误如下。

没办法，只能各种搜索，各种重装，最后发现原先的nodejs、npm版本有些老了，所以导致的问题，具体操作如下：
Step 1: Remove Yeoman
$ npm uninstall -g yo
Step 2: Clear NPM Cache
$ npm cache clean
Step 3: Upgrade NPM to latest version
$ npm install -g npm
Step 4: Install Yeoman
$ npm install -g yo
