To install Laravel using composer, all you need to do is to run in your terminal is:

要使用 composer 安装 Laravel，您需要做的就是在终端中运行：

composer create-project --prefer-dist laravel/laravel blog

Where: blogis the name of the folder containing your new Laravel instance.

其中：blog是包含新 Laravel 实例的文件夹的名称。

To install Laravel directly within your chosen directory (not in a folder within it as demonstrated above), simply run the same command but this time without a folder name as in:

要直接在您选择的目录中安装 Laravel（而不是在上面演示的文件夹中），只需运行相同的命令，但这次没有文件夹名称，如下所示：

composer create-project --prefer-dist laravel/laravel

Remember to run the command within your desired directory for the project; in your case, for C:\xampp\htdocs\, then, run either the first or second command as above base on your needs.

请记住在项目所需的目录中运行该命令；在您的情况下， for C:\xampp\htdocs\，然后，根据您的需要运行上述第一个或第二个命令。

This assumes you already have Composer properly installed as recommended on their website.

这假设您已经按照他们网站上的建议正确安装了 Composer 。

Before you try addressing your failed to open stream:error, do avoid having folder names with space(s) as in your command above (obviously not the source of the error).

在尝试解决failed to open stream:错误之前，请避免使用上面命令中包含空格的文件夹名称（显然不是错误的根源）。

Make sure you have the correct Server Requirements for Laravel
the failed to open stream:error usually occur when the OpenSSL PHP Extension not enabled.

请确保您有Laravel正确的服务器要求
的failed to open stream:不启用OpenSSL的PHP扩展的错误时，通常会出现。

• PHP >= 5.6.4
• OpenSSL PHP Extension
• PDO PHP Extension
• Mbstring PHP Extension
• Tokenizer PHP Extension
• XML PHP Extension

• PHP >= 5.6.4
• OpenSSL PHP 扩展
• PDO PHP 扩展
• Mbstring PHP 扩展
• 分词器 PHP 扩展
• XML PHP 扩展

After enabling the required extension(s), do remember to restart your server, then run the following command:

启用所需的扩展后，请记住重新启动服务器，然后运行以下命令：

composer update
