Well I discovered what generated the error.
好吧，我发现了产生错误的原因。
In config/services.phpI was doing this:
在config/services.php我这样做：
'facebook' => [
'client_id' => env('FACEBOOK_APP_ID', null),
'client_secret' => env('FACEBOOK_APP_SECRET', null),
'redirect' => url('auth/facebook'),
]
url('auth/facebook')is what caused the error.
url('auth/facebook')是什么导致了错误。

As you figured out, the problem is caused by using url() in config. The same would happen if you used asset(). When running artisan commands, the framework can't figure out what the website url is, hence the error.
正如您所发现的，问题是由在配置中使用 url() 引起的。如果您使用 asset()，也会发生同样的情况。运行 artisan 命令时，框架无法确定网站 url 是什么，因此出现错误。
I just want to propose an alternative solution:
我只想提出一个替代解决方案：
'facebook' => [
'client_id' => '***'
'client_secret' => '***',
'redirect' => PHP_SAPI === 'cli' ? false : url('/fb-callback-path'),
]
I don't love it but it's very unlikely you're ever going to need your FB redirects when running command line scripts and this way you don't have to remember about configuring the redirect in each environemnt.
我不喜欢它，但是在运行命令行脚本时您不太可能需要 FB 重定向，这样您就不必记住在每个环境中配置重定向。

该问题是由在配置中使用 url() 引起的。我从 config/filesystems.php 中删除了它，它起作用了！我希望能帮到你！
