The logs are located in storagedirectory. If you want laravel to display the error for you rather than the cryptic 'Whoops' message, copy the .env.exampleto .envand make sure APP_ENV=localis in there. It should then show you the detailed error messaging.

日志位于storage目录中。如果您希望 laravel 为您显示错误而不是神秘的“Whoops”消息，请复制.env.example到.env并确保APP_ENV=local在那里。然后它应该向您显示详细的错误消息。

This is happening because there is a field in .envfile named, APP_KEY, which is blank now, we need some random key for this variable.

发生这种情况是因为.env文件中有一个名为APP_KEY的字段，它现在是空白的，我们需要这个变量的一些随机键。

Follow these steps to get rid of this problem.

请按照以下步骤解决此问题。

1) .env.exampleto .env

1) .env.example到.env

2) Go to your root directory in your command prompt (If you are using windows)/terminal (If you are using MAC or LINUX) where you have installed laravel project/files and run following command

2）在你安装了laravel项目/文件的命令提示符（如果你使用的是Windows）/终端（如果你使用的是MAC或LINUX）中转到你的根目录并运行以下命令

php artisan key:generate

php artisan key:generate

and then run your project. It's all done.

然后运行你的项目。这一切都完成了。

• Give write permission to storage and bootstrap/cache directories
• Rename .env.example file to .env
• If you get "RuntimeException... No supported encrypter found. The cipher and / or key length are invalid." error, stop the application and generate key from command line "php artisan key:generate"
• If your get "OpenSSL extension is required" error, enable the openssl extension by opening php.ini in php installation folder and uncommenting the line extension=php_openssl.dll by removing the semicolon at the beginning

• 授予存储和引导程序/缓存目录的写权限
• 将 .env.example 文件重命名为 .env
• 如果您收到“RuntimeException...未找到支持的加密器。密码和/或密钥长度无效。” 错误，停止应用程序并从命令行“php artisan key:generate”生成密钥
• 如果您收到“需要 OpenSSL 扩展”错误，请通过打开 php 安装文件夹中的 php.ini 并通过删除开头的分号取消注释 extension=php_openssl.dll 行来启用 openssl 扩展

In Laravel 5.5, I had the same issue

在 Laravel 5.5 中，我遇到了同样的问题

.env

was added to .gitignore.

已添加到 .gitignore。

So Either remove ".env" it from .gitignore file.

所以要么从 .gitignore 文件中删除“.env”它。

or add it forcefully

或者强行添加

git add .env -f

And Deploy it. It will work.

并部署它。它会起作用。

If above does not help. Try generating the Key Again

如果以上没有帮助。尝试再次生成密钥

php artisan key:generate

BECAUSE IF After Creating the .env file or/and Generating the Key by

因为如果在创建 .env 文件或/和通过以下方式生成密钥后

just as explained previously by others, and it still persists Try the following:

-rw-rwx--- 1 www-data rootuser 575 Nov 4 06:34 pathto/.env

-rw-rwx--- 1 www-data rootuser 575 Nov 4 06:34 pathto/.env

This as stated above should resolve it. Especially when your laravel.log file keeps complaining that the key hasn't been generated or added.

这如上所述应该解决它。特别是当您的 laravel.log 文件不断抱怨尚未生成或添加密钥时。
