windows下 composer常见错误及处理。

错误一：

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：

错误二：

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"

见文档：

https://getcomposer.org/doc/articles/troubleshooting.md#xdebug-impact-on-composer

错误三：

on line 272

解决办法：

删除composer资源插件，再重新安装

Linux : rm -rf ~/.composer/vendor/fxp

Windows : rm -r %APPDATA%\Composer\vendor\fxp

重新安装：

composer global require "fxp/composer-asset-plugin:~1.0.3"

如果还有其它错误，可尝试全局更新：

composer global update

解决办法：

Yii2 需要 composer-plugin-api 1.0 以上的版本，运行以下命令：

composer global require "fxp/composer-asset-plugin:~1.1.1" 

错误五：

解决办法：

在C:/user/Administrator/AppData/Roaming/Composer下创建auth.json写入从github上生成的access token
