提示：扫一扫查出行【扫一扫了解最新限行尾号】
复制提示
1：下载 ca-bundle.crt和cacert.pem
将这两个文件放在php目录下
2:php.ini中添加上述两个文件的路径
curl.cainfo=C:/xampp/php/ca-bundle.crt
openssl.cafile=C:/xampp/php/ca-bundle.crt
写到最后一行就可以
3：下载Composer-Setup.exe
https://getcomposer.org/download/
在该页面找到Composer-Setup.exe并下载安装（要求能vpn翻墙）
4：安装如果出现错误
Notice: Undefined variable: caBundle in - on line 892
出现该错误的时候，找到错误路径打开install文件，找到892行
红线的地方报caBundle未定义，手动改成如下：
改完之后保存文件，并且退出Composer-Setup.exe（不要继续安装），然后重新安装，不报错，走完安装过程
5：验证安装结果：
6：安装Yii2
在服务器上建立访问目录yii2，
在github的个人信息的设置上生成一个token，后面创建项目的时候提示token(hidden)的时候将这个token复制上去

安装Yii2的最新版本，
注意要将下面这两行创建命令
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
改为：
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项目：
composer create-project yiisoft/yii2-app-advanced advanced 2.0.6然后等待安装，cmd显示如下：
