检查您的 PHP 版本

我已经用“echo phpversion()”检查过了，它显示 7.0.13

Change PHP version used by Composer on Windows的可能重复

【参考方案1】：

你需要做两件事之一。

解决方案 1 - 您需要更新您的 PHP 版本。如果您没有正确的版本，Laravel 将无法正常运行。

解决方案 2 - 也许您有正确的 PHP 版本，但由于某种原因，composer 看不到。轻松修复，您只需要使用--ignore-platform-reqs 命令。无论 PHP 版本如何，这将允许您使用 composer 安装东西。

【参考方案2】：

我刚才遇到了这个问题，我通过将路径环境变量从操作系统更改为指向包含最新 php 版本的 wamp php 文件夹来修复它。 为了做到这一点（我也必须研究这个） - 我去了这个链接并按照说明操作：https://www.java.com/en/download/help/path.xml

旧的 Path 变量如下所示：C:\wamp64\bin\php\php5.6.25 我将其更改为 C:\wamp64\bin\php\php7.0.10 保存所有内容，关闭所有内容，重新启动我的电脑，然后它就没有问题了。 希望这可以为某人节省一些研究时间。

【参考方案3】：

已经解决了。看来我的系统正在使用 IIS Express 的另一个 php 版本，它使用旧版本的 php。我只是将环境变量更改为指向具有最新 php 版本的 xampp php
