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)$HOME/.npmrc
prefix=${HOME}/.npm-packages

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

/home/y/.npm-packages/bin/grunt -> /home/y/.npm-packages/lib/node_modules/grunt-cli/bin/grunt
/home/y/.npm-packages/bin/yo -> /home/y/.npm-packages/lib/node_modules/yo/lib/cli.js

> yo@1.4. postinstall /home/y/.npm-packages/lib/node_modules/yo
> yodoctor
