今天打算学习一下Yii,但是在安装过程中出现了很多问题。
通过composer安装：
composer global require "fxp/composer-asset-plugin:~1.1.1" composer create-project --prefer-dist yiisoft/yii2-app-basic basic
第一条命令安装 Composer asset plugin，它是通过 Composer 管理 bower 和 npm 包所必须的，此命令全局生效，一劳永逸。 第二条命令会将 Yii 安装在名为 basic 的目录中，你也可以随便选择其他名称。
但是在安装过程中就报了一个异常如下：
[Symfony\Component\Process\Exception\RuntimeException] The Process class relies on proc_open, which is not available on your PHP installation.
解决方法：
在php.ini中，找到disable_functions选项，看看后面是否有proc_open函数被禁用了，如果有的话，去掉即可。
希望对大家有所帮助。
然而删除之后，又报了异常
[ErrorException] proc_get_status() has been disabled for security reasons
同样道理，proc_get_status被禁用了，只要把proc_get_status删了即可。
错误还在继续。。。

在github的setting/Personal access tokens下面建立token，然后直接将token复制粘贴放到Token (hidden): ***后面即可。
回车后如果出现
Token stored successfully.
表示token验证成功。
下面是安装进程：
