windows下 composer常见问题及处理。

问题一：

Warning: This development build of composer is over 30 days old. It is recommend

ed to update it by running "C:\ProgramData\ComposerSetup\bin\composer.phar self-

update" to get the latest version.

解决方法：

composer selfupdate

如下图：





问题二：

You are running composer with xdebug enabled. This has a major impact on runtime

performance. See https://getcomposer.org/xdebug

如图：





解决方法：

打开php.ini，在zend_extension前加分号

;zend_extension = "d:/wamp/bin/php/php5.5.12/zend_ext/php_xdebug-2.2.5-5.5-vc11-x86_64.dll"

前面的分号去掉，见文档：
