SOLUTION:laravel new project-namewas actually giving me an error that i overlooked. I had the wrong version of php. It requiresphpv7.1.3 or higher. If you don't have it it doesn't work.
解决方案：laravel new project-name实际上给了我一个我忽略的错误。我有错误的 php 版本。它需要phpv7.1.3 或更高版本。如果你没有它，它就不起作用。

I ran laravel new blogfrom their getting started page. When I tried to run php artisan serve, I got the following error:
我laravel new blog从他们的入门页面跑了。当我尝试运行时 php artisan serve，出现以下错误：
Warning: require(C:\Projects\laravel-projects\blog/vendor/autoload.php): failed to open stream: No such file or directory in C:\Projects\laravel-projects\blog\artisan on line 18
警告：require(C:\Projects\laravel-projects\blog/vendor/autoload.php): 无法打开流：C:\Projects\laravel-projects\blog\artisan 中第 18 行没有这样的文件或目录
The artisan file is pointing to
工匠文件指向
require __DIR__.'/vendor/autoload.php';
this directory does not exist. Even if I point it to the correct directory, it still wouldn't work because I don't have read permissions for that folder (so it gets denied).
该目录不存在。即使我将它指向正确的目录，它仍然无法工作，因为我没有该文件夹的读取权限（因此它被拒绝）。
What's going on, and how can I fix this?
这是怎么回事，我该如何解决？

由于某种原因，这非常有效。现在。出现了新错误。

When running laravel new project_name. It outputted the text php 7.1.3 or higher needs to be installed. Current version 5.6 does not match requirements. And it aborts without plainly giving you an error. Be sure to download php version 7.1.3 or higher. Also check if you have environment variables for earlier versions of php and delete those.
运行 laravel 时新建 project_name。它输出文本需要安装 php 7.1.3 或更高版本。当前版本 5.6 不符合要求。它会中止而不会明显地给你一个错误。请务必下载 php 7.1.3 或更高版本。还要检查您是否有早期版本的 php 的环境变量并删除它们。
note: be sure to read install.txt from the php download
注意：一定要从 php 下载中读取 install.txt
