无法使用gmail对SMTP服务器进行身份验证错误

我正在尝试为我的第一个laravel项目设置电子邮件，很高兴看到它有一个laracast: https://laracasts.com/lessons/mailers

I'm trying to set up email for my first laravel project, and was thrilled that there's a laracast for it: https://laracasts.com/lessons/mailers

我已经按照简单的步骤操作，在mail.php中选择了gmail(为匿名添加了x):

I've followed the simple steps, chose gmail in mail.php (x's added for anonymity):

'driver' => env('MAIL_DRIVER', 'smtp'),
'host' => env('MAIL_HOST', 'smtp.gmail.com'),
'port' => env('MAIL_PORT', 587),
'from' => ['address' => 'dianexxxxx@gmail.com', 'name' => 'Diane Kaplan'],
'encryption' => env('MAIL_ENCRYPTION', 'tls'),
'username' => 'dianexxxxx@gmail.com',
'password' => 'xxxxx',
'sendmail' => '/usr/sbin/sendmail -bs',
'pretend' => false,

.env有(为匿名添加了x)-播报中没有让我们使用MAIL_USERNAME和MAIL_PASSWORD，但假设我稍后再从中拉出，它们会进行很好的更新:

.env has (x's added for anonymity)- the laracast doesn't have us use MAIL_USERNAME and MAIL_PASSWORD, but they're updated for good measure assuming I'll pull from there later:

MAIL_DRIVER=smtp
MAIL_HOST=mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=dianexxxxx@gmail.com
MAIL_PASSWORD=xxxxxx
MAIL_ENCRYPTION=null

但是在尝试发送邮件的最初一刻(3:30标记)时，出现了身份验证错误: AuthHandler.php第181行中的Swift_TransportException: 无法使用3个可能的身份验证器在用户名为"dianexxxxx@gmail.com"的SMTP服务器上进行身份验证

But in the first little moment of truth trying to send a mail (3:30 mark), I get an authentication error: Swift_TransportException in AuthHandler.php line 181: Failed to authenticate on SMTP server with username "dianexxxxx@gmail.com" using 3 possible authenticators

基于一点堆栈溢出读数，我尝试在我的gmail设置中打开访问不太安全的应用程序"，但错误没有变化. (有关此问题的其他帖子还有其他因素比我的问题更严重).

Based on a little stackoverflow reading, I tried turning on 'access to less secure apps' in my gmail settings, but no change in the error. (And the other posts about this issue had other factors that made a fancier problem than mine).

从laravel.log(下)没什么让我惊讶的-有什么想法吗?

Nothing jumps out at me from laravel.log (below)- any ideas?
