我住在伊朗，在过去的日子里，因为互联网的限制，我不能推到GitHub或GitLab，也不能使用 composer 。
对于GitHub和GitLab，我尝试了SSH连接和SSH访问密钥，还没有问题！但是我不能使用Composer。
当我尝试这个
composer create-project laravel/laravel starter-app
我明白了

Creating a "laravel/laravel" project at "./starter-app"
Info from https://repo.packagist.org: #StandWithUkraine
Cannot use laravel/laravel's latest version v9.3.8 as it requires PHP ^8.0.2 which is not satisfied by your platform.

Cloning failed using an SSH key for authentication, enter your GitHub credentials to access private repos
When working with _public_ GitHub repositories only, head to https://github.com/settings/tokens/new?scopes=&description=Composer+on+DESKTOP-RRHGV12+2022-10-11+1350 to retrieve a token.
This token will have read-only permission for public information only.
When you need to access _private_ GitHub repositories as well, go to https://github.com/settings/tokens/new?scopes=repo&description=Composer+on+DESKTOP-RRHGV12+2022-10-11+1350
Note that such tokens have broad read/write permissions on your behalf, even if not needed by Composer.
Tokens will be stored in plain text in "C:/Users/VIRA-PC03/AppData/Roaming/Composer/auth.json" for future use by Composer.
For additional information, check https://getcomposer.org/doc/articles/authentication-for-private-packages.md#github-oauth
Token (hidden):

我转到此链接“https://getcomposer.org/doc/articles/authentication-for-private-packages.md#github-oauth“并生成新令牌并粘贴它，但没有任何React，而且我无法使用composer
我还尝试了composer diagnose命令，得到了

然后我转到C：\users\AppData\Roaming\composer，创建文件“auth.json”并将其放入其中

{
    "github-oauth": {
        "github.com": "my token"
    }
}

但我无法使用Composer获得或安装Laravel或任何其他包（如phpspeadsheet）。
