Laravel错误-类setEventDispatcher不存在 [英] Laravel error - Class setEventDispatcher does not exist
问题描述
运行php artisan serve并访问我的主页时出现此错误:
I'm getting this error, when I run php artisan serve and visit my home page:
ReflectionException (-1)
Class setEventDispatcher does not exist
详细信息
Laravel版本:5.6.39 环境:当地 操作系统:macOS Mojave 10.14.2

Laravel version: 5.6.39 Environment: local OS: macOS Mojave 10.14.2
它开始了，当我在另一个项目中使用npm出现错误时，所以我重新安装了节点(通过这种方式).
It started, when I got an error using npm (in another project), so I reinstalled Node (this way).
执行完此操作后，将无法启动该项目(存在问题).运行php artisan serve时出现此错误:
After doing that, then this project (in question) couldn't be started. I was getting this error, when running php artisan serve:
dyld: Library not loaded: /usr/local/lib/libpng16.16.dylib with anything php related
Referenced from: /usr/local/bin/php
Reason: image not found
该错误已由更新和升级brew 解决.
然后，我有能力启动项目(php artisan serve).但是当我访问主页时，显示此错误:
Then I was capable of starting the project (php artisan serve). But when I visit the home page, this error was shown:
ReflectionException (-1)
Class setEventDispatcher does not exist
如果我遵循堆栈跟踪，那么我可以看到正是这条线(来自我的homeController)触发了错误:
If I follow the stack trace, then I can see that it was this line (from my homeController) that triggered the error:
if( ! Auth::check() ){
return view( 'pages.home' );
}
如果我将其注释掉，则在使用Auth -module的另一个地方也会发生相同的错误.
If I commented that out, then the same error occured from another place, where the Auth-module was being used.
这是堆栈跟踪:
有人知道如何解决这个问题吗?我在Google上找不到任何有希望的结果，而且我也不知道为什么会这样...:-/
Does anyone know how to resolve this? I can't find any promising results on Google, - and I have no idea why this happens... :-/
我尝试了composer clear-cache并删除了供应商文件夹，然后执行了composer install，问题仍然出现.
I tried composer clear-cache and deleting the vendor-folder, and then doing a composer install and the problem still occured.
我也按照Marcus的建议检查了我的服务提供商-但我真的不知道在那儿寻找什么.一切看起来都很规律(没有花哨的if陈述或其他内容).
I also checked my Service Providers, as Marcus suggested, - but I don't really know what to look for in there. It all looks pretty regular (no fancy if-statements or anything).
我意识到，我无法使用Sequel Pro连接到数据库.这是因为Brew将我的MySQL版本从5.5更新到了8.0.
I realized, that I couldn't connect to my database using Sequel Pro. And it was because Brew had updated my MySQL-version from 5.5 to 8.0.
这是通过按照以下方式进行 来解决的(我做了很多事情，所以我可能会错过很多步骤):
That was resolved by doing something along these lines (I did a bunch of stuff, so I might be missing a coulple of steps):
brew unlink mysql
brew install mysql@5.7
brew switch mysql 5.7.21
brew link mysql
，然后我可以使用mysql --version验证版本.该MySQL版本更改也存在一些权限问题，但是我正在发出该消息，因此不会太长.
and I could then verify the version with mysql --version. I also had some permission issues with that MySQL-version-change, but I'm emitting that, so this doesn't get too long.
我尝试禁用 Laravel调试栏(通过将其从composer.json中删除，删除composer.lock和vendor，然后运行composer install).这样就解决了！ ... 但！
I tried disabling the Laravel Debugbar (by deleting it from composer.json, deleting composer.lock and vendor and then running composer install). And that fixed it!! ... But!
后来我尝试安装Barryvdh的 IDE帮助器，然后安装完全相同的错误又回来了！！?
When I later tried to install Barryvdh's IDE Helper, then the exact same error came back!?
我执行了以下三个步骤，以安装IDE Helper(并重新引入该错误):
I performed these three steps, to install the IDE Helper (and re-introduce the error):
-
从我的目录的根目录运行此命令:
curl https://gist.githubusercontent.com/barryvdh/5227822/raw/4be028a27c4ec782965bb8f2fdcb4c08c71a441d/_ide_helper.php -o _ide_helper.php
将这些行添加到app/Provider/AppServiceProvider.php:
...
if ($this->app->environment() !== 'production') {
$this->app->register(\Barryvdh\LaravelIdeHelper\IdeHelperServiceProvider::class);
}
- 运行此命令:
composer require --dev barryvdh/laravel-ide-helper
所以我回到了这个错误:
So I'm back at this error:
ReflectionException (-1)
Class setEventDispatcher does not exist
...堆栈跟踪与先前显示的相同(从Container.php弹出).
... The stack trace is identical to the one shown previously (sprung from Container.php).
推荐答案
尝试了每个解决方案，但没有一个起作用.
Tried every solution, none of them worked.
最后，我意识到，尝试将php升级到7.3.3时，实际上是导致失败的网络错误.阅读日志，再次尝试，重新启动代客服务，然后再次尝试.
Finally, i realised that when trying to upgrade php to 7.3.3 it was infact a network error that caused the fail. Read the logs, tried again, restarted valet and tried again.
现在可以使用.
升级到7.3.3确实是解决方案.
Upgrading to 7.3.3 was the solution indeed.
谢谢！
