使用grunt serve运行时遇到一问题：
y@y:ydkt$ grunt serve Running "serve" task Running "clean:server" (clean) task Cleaning .tmp...OK Running "env:all" (env) task Running "injector:sass" (injector) task Missing option `template`, using `dest` as template instead Injecting scss files (18 files) >> Nothing changed Running "concurrent:server" (concurrent) task Warning: Running "sass:server" (sass) task Warning: You need to have Ruby and Sass installed and in your PATH for this task to work.

问题是：提示我Ruby 与Sass未进行安装配置：
Warning: Running "sass:server" (sass) task Warning: You need to have Ruby and Sass installed and in your PATH for this task to work. More info: https://github.com/gruntjs/grunt-contrib-sass Use --force to continue.
我 ruby -v 查看了以下ruby 版本为1.9.1 ubuntu已经进行预装了，查看了以下需要安装compass才可以编译sass．
下面进行安装compass：
y@y:ydkt$ sudo gem install compass Fetching: sass-3.4.14.gem (100%) Fetching: multi_json-1.11.0.gem (100%) Fetching: compass-core-1.0.3.gem (100%) Fetching: compass-import-once-1.0.5.gem (100%) Fetching: chunky_png-1.3.4.gem (100%) Fetching: rb-fsevent-0.9.5.gem (100%) Fetching: ffi-1.9.8.gem (100%) Building native extensions. This could take a while... ERROR: Error installing compass: ERROR: Failed to build gem native extension. /usr/bin/ruby1.9.1 extconf.rb /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- mkmf (LoadError) from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require' from extconf.rb:4:in `<main>' Gem files will remain installed in /var/lib/gems/1.9.1/gems/ffi-1.9.8 for inspection. Results logged to /var/lib/gems/1.9.1/gems/ffi-1.9.8/ext/ffi_c/gem_make.out
提示我ruby 版本过低，
Gem files will remain installed in /var/lib/gems/1.9.1/gems/ffi-1.9.8 for inspection
下一步要更新我的ruby 版本，安装2.1.2
sudo apt-get -y update sudo apt-get install cmake sudo apt-get install -y build-essential zlib1g-dev libyaml-dev libssl-dev libgdbm-dev libreadline-dev libncurses5-dev libffi-dev curl git-core openssh-server redis-server postfix checkinstall libxml2-dev libxslt-dev libcurl4-openssl-dev libicu-dev mysql-client libmysqlclient-dev libreadline6-dev curl --progress http://cache.ruby-lang.org/pub/ruby/2.1/ruby-2.1.2.tar.gz | tar xz cd ruby-2.1.2 ./configure make sudo make install
安装成功：
y@y:~$ ruby -v ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-linux] y@y:~$
再次重新安装compass:
y@y:ydkt$ sudo gem install compass [sudo] password for y: Fetching: sass-3.4.14.gem (100%) Successfully installed sass-3.4.14 Fetching: multi_json-1.11.0.gem (100%) Successfully installed multi_json-1.11.0 Fetching: compass-core-1.0.3.gem (100%) Successfully installed compass-core-1.0.3 Fetching: compass-import-once-1.0.5.gem (100%) Successfully installed compass-import-once-1.0.5 Fetching: chunky_png-1.3.4.gem (100%) Successfully installed chunky_png-1.3.4 Fetching: rb-fsevent-0.9.5.gem (100%) Successfully installed rb-fsevent-0.9.5 Fetching: ffi-1.9.8.gem (100%) Building native extensions.

此时执行grunt serve,之前的错误已经没有了，但是又出现了新的错误：
Running "open:server" (open) task Warning: Command failed: /bin/sh -c /home/y/my_git/ydkt/node_modules/open/vendor/xdg-open "http://localhost:9000" /bin/sh: 1: /home/y/my_git/ydkt/node_modules/open/vendor/xdg-open: Permission denied Use --force to continue. Aborted due to warnings.
提示：拒绝访问！修改文件权限：
y@y:open$ cd vendor/ y@y:vendor$ chmod 777 xdg-open y@y:vendor$ ll 总用量 28 drwxrwxr-x 2 y y 4096 5月 30 09:31 ./ drwxrwxr-x 4 y y 4096 5月 11 15:28 ../ -rwxrwxrwx 1 y y 19086 5月 11 15:28 xdg-open* y@y:vendor$
最后执行grunt serve成功！！！
