解决方法参照：https://github.com/sindresorhus/guides/blob/master/npm-global-without-sudo.md
(1)mkdir "${HOME}/.npm-packages"
(2).bashrc
NPM_PACKAGES="${HOME}/.npm-packages"
NODE_PATH="$NPM_PACKAGES/lib/node_modules:$NODE_PATH"
PATH="$NPM_PACKAGES/bin:$PATH"
unset MANPATH # delete if you already modified MANPATH elsewhere in your config
MANPATH="$NPM_PACKAGES/share/man:$(manpath)"
(3)$HOME/.npmrc

２：再次安装：y@y:~$ npm install --global yo bower grunt-cli
提示：npm WARN optional dep failed, continuing uglify-js@~2.3
解决方法：y@y:~$sudo npm cache clean
３：查看npm配置信息
y@y:~$ npm config get prefix
/home/y/.npm-packages
进行安装：y@y:~$ npm install --global yo bower grunt-cli
