1：下載 ca-bundle.crt和cacert.pem
將這兩個文件放在php目錄下
2:php.ini中添加上述兩個文件的路徑
curl.cainfo=C:/xampp/php/ca-bundle.crt
openssl.cafile=C:/xampp/php/ca-bundle.crt
寫到最后一行就可以
3：下載Composer-Setup.exe
https://getcomposer.org/download/
在該頁面找到Composer-Setup.exe並下載安裝（要求能vpn翻牆）
4：安裝如果出現錯誤
Notice: Undefined variable: caBundle in - on line 892
出現該錯誤的時候，找到錯誤路徑打開install文件，找到892行
紅線的地方報caBundle未定義，手動改成如下：
改完之后保存文件，並且退出Composer-Setup.exe（不要繼續安裝），然后重新安裝，不報錯，走完安裝過程
5：驗證安裝結果：
6：安裝Yii2
在服務器上建立訪問目錄yii2，
在github的個人信息的設置上生成一個token，后面創建項目的時候提示token(hidden)的時候將這個token復制上去

安裝Yii2的最新版本，
注意要將下面這兩行創建命令
php composer.phar global require "fxp/composer-asset-plugin:~1.1.1"
php composer.phar create-project yiisoft/yii2-app-basic basic 2.0.6
改為：
composer global require "fxp/composer-asset-plugin:~1.1.1"
composer create-project yiisoft/yii2-app-basic basic 2.0.6
如果是advanced項目：
composer create-project yiisoft/yii2-app-advanced advanced 2.0.6
然后等待安裝，cmd顯示如下：
