通过命令行查看

npmconfiggetprefix

如果是user/local则可以执行下面的语句，如果只是user那么采用第二种方式（将node的文件夹移走）

sudochown-R$(whoami)$(npmconfiggetprefix)/{lib/node_modules,bin,share}

将对应的文件夹授权

变量whoami就是当前用户的文件夹位置，npmconfiggetprefix就是npm中配置的安装目录前缀

然后执行cd&&npminstallyo-g

貌似如果之前安装过yo，在/usr/local/bin/下已经存在yo的情况下，执行npminstallyo-g会不允许，所以要cd&&
