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

/usr/local/node/lib/node_modules/.yo_npminstall/configstore/1.4.0/configstore/index.js:

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
