使用Ctrl+`快捷键或者通过View->Show Console菜单打开命令行，粘贴如下代码：
import urllib.request,os; pf = 'Package Control.sublime-package'; ipp = sublime.installed_packages_path(); urllib.request.install_opener( urllib.request.build_opener( urllib.request.ProxyHandler()) ); open(os.path.join(ipp, pf), 'wb').write(urllib.request.urlopen( 'http://sublime.wbond.net/' + pf.replace(' ',' ')).read())这是我另外一篇安装PHPstudy的博客，可以参照来做http://blog.csdn.net/post_mans/article/details/74076555

[root@localhost bin]# wget https://dl.laravel-china.org/composer.phar -O /usr/local/bin/composer [root@localhost bin]# chmod a+x /usr/local/bin/composer ##注意如果composer没有反应，出现以下问题，就是没有把PHP添加到系统环境变量 [root@localhost bin]# composer /usr/bin/env: php: 没有那个文件或目录 ### ###安装你按装的PHP的bin目录，我自己没有用phpstudy！根据实际情况找到PHP的bin目录 ##修改/etc/profile文件使其永久性生效，并对所有系统用户生效，在文件末尾加上如下两行代码(后面继续加的要以冒号隔开) PATH=$PATH:/usr/local/webserver/php/bin: ##最后：执行 命令source /etc/profile 使其修改生效，执行完可通过echo $PATH命令查看是否添加成功。 ##然后再输入composer [root@localhost bin]# composer Do not run Composer as root/super user!
