安装yii2高级模板时出现问题

当我执行以下操作时，我的Yii2安装需要一些帮助：

composer create-project --prefer-dist yiisoft/yii2-app-advanced yii2advanced

我明白了：

PS C:\xampp\htdocs> composer create-project --prefer-dist yiisoft/yii2-app-advanced yii2advanced
Installing yiisoft/yii2-app-advanced (2.0.16)
  - Installing yiisoft/yii2-app-advanced (2.0.16): Loading from cache
Created project in yii2advanced
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for codeception/verify ~1.0.0 -> satisfiable by codeception/verify[1.0.0].
    - codeception/verify 1.0.0 requires php >= 7.0 -> your PHP version (5.6.15) does not satisfy that requirement.
  Problem 2
    - phpunit/phpunit 6.5.9 requires php ^7.0 -> your PHP version (5.6.15) does not satisfy that requirement.

    - phpunit/phpunit 6.5.5 requires php ^7.0 -> your PHP version (5.6.15) does not satisfy that requirement.
    - phpunit/phpunit 6.5.14 requires php ^7.0 -> your PHP version (5.6.15) does not satisfy that requirement.
    - phpunit/phpunit 6.5.13 requires php ^7.0 -> your PHP version (5.6.15) does not satisfy that requirement.
    - phpunit/phpunit 6.5.12 requires php ^7.0 -> your PHP version (5.6.15) does not satisfy that requirement.
    - phpunit/phpunit 6.5.11 requires php ^7.0 -> your PHP version (5.6.15) does not satisfy that requirement.
    - phpunit/phpunit 6.5.10 requires php ^7.0 -> your PHP version (5.6.15) does not satisfy that requirement.
    - Installation request for phpunit/phpunit ~6.5.5 -> satisfiable by phpunit/phpunit[6.5.10, 6.5.11, 6.5.12, 6.5.13, 6.5.14, 6.5.5, 6.5.6, 6.5.7, 6.5.8, 6.5.9].

PS C:\xampp\htdocs>

我对基本模板没有问题

现在高级应用程序需要PHP7吗？。

---

如果没有PHP7，我如何安装它？

开发人员意外地向composer添加了

“phpunit/phpunit”：“~6.5.5”

，composer需要

“php:^7.0”

您可以尝试添加

——忽略平台需求

composer创建项目--首选距离--忽略平台需求yiisoft/yii2应用程序高级yii2高级

或

使用
composer config-g-e
添加假php进行编辑

{
    "config": {
        "platform":{
            "php":"7.0"
        }
    }
}

我觉得很棒。谢谢你为我工作。非常感谢。
