麻烦安装laravel依赖项

Question

*我正在运行Windows 10。

我打开cmd并输入：

composer create-project laravel/laravel **project_name**

我在cmd中获得以下行：

You are running Composer with SSL/TLS protection disabled.
Loading composer repositories with package information

但似乎一切都很好，文件夹结构也是正确的。

然后我键入以下commnad以下载我的所有dependecies [vendor dir]：

composer install

我在cmd中获得以下行：

您正在运行已禁用SSL / TLS保护的Composer。 使用包信息加载composer存储库 警告：通过http访问packagist.org，这是一种不安全的协议。 更新依赖项（包括require-dev） 您的要求无法解析为可安装的软件包。

它从来没有发生在我之前，我无法在这里或谷歌找到解决方案。
谢谢。

PS

我重新安装了php到C：/ php 我将php.ini文件解压缩到C：/ 我设置了环境变量 我也取消注释了扩展名

Answer 1

恭喜！

最后我找到了解决方案。
我已经卸载了作曲家，我发现我的电脑里有2个php配置。 我删除了位于xampp文件夹之外的配置。 我已经下载了一个新的PHP，将其解压缩到xampp文件夹中 （您需要将php.ini-development文件更改为：php.ini） 然后你必须找到（ctrl + f）：extension_dir并将其修改为我的路径C：/ xampp / php / ext 然后安装了composer，找到了php.exe然后它说openresl有问题所以我在php.ini文件中修改了相关的扩展名（只需删除;） 现在它工作得很好。

谢谢您的帮助
