I am building a project using Laravel. It was working fine on localhost, but when I upload it to the server (the server has comodo ssl installed), I receive the following error:

我正在使用 Laravel 构建一个项目。它在本地主机上运行良好，但是当我将它上传到服务器（服务器安装了 comodo ssl）时，我收到以下错误：

Do you have all the necessary extensions installed on the server?

您是否在服务器上安装了所有必要的扩展？

• PHP >= 5.5.9
• OpenSSL PHP Extension
• PDO PHP Extension
• Mbstring PHP Extension
• Tokenizer PHP Extension

• PHP >= 5.5.9
• OpenSSL PHP 扩展
• PDO PHP 扩展
• Mbstring PHP 扩展
• 分词器 PHP 扩展

It could be that you're missing the OpenSSL extension. Also, do you have the key set in .envfile?

可能是您缺少 OpenSSL 扩展。另外，您是否在.env文件中设置了密钥？

Answer: the 'cipher' => ''was not set.

回答by onavascuez

You only type in console:

您只需在控制台中输入：

php artisan key:generate

And if your app.php not change this Key, change manually.

如果您的 app.php 没有更改此 Key，请手动更改。

Next if you should then happen to get this error message:

接下来，如果您应该碰巧收到此错误消息：

[ErrorException]
file_get_contents(/path/to/my/project/.env): failed to open stream: No such file or directory

[ErrorException]
file_get_contents(/path/to/my/project/.env): 无法打开流：没有这样的文件或目录

Then make a copy of the .env.examplefile and try again:

然后复制该.env.example文件并重试：

cp .env.example .env
php artisan key:generate

I have same issue before and I fixed it follow this way: Go to config/app.php, change "cipher" => "anything"to

我之前遇到过同样的问题，我按照这种方式修复了它：转到 config/app.php，更改"cipher" => "anything"为

'cipher' => MCRYPT_RIJNDAEL_128,

I just fix error.

我只是修复错误。

1. Shift+Clickright mouse to "open commend window here" from your root project.
2. In console write: "php artisan key:generate".
3. Get 32 character 'Mark' to config/app.phplike 'key' => env('APP_KEY', 'insert get 32 char key'),//line number 81

1. Shift+Click鼠标右键从您的根项目“在此处打开推荐窗口”。
2. 在控制台写："php artisan key:generate".
3. Get 32​​ character 'Mark' to config/app.phplike 'key' => env('APP_KEY', 'insert get 32 char key'),//行号81

回答by Tirth Patel

In root directory, if there is .env.examplefile then change it to .envand then run php artisan key:generate. This worked for me.

在根目录中，如果有.env.example文件则将其更改为.env然后运行php artisan key:generate. 这对我有用。

In my case, I need to enable mcrypt extension.

就我而言，我需要启用 mcrypt 扩展。

But first, check if you already have it:

但首先，检查您是否已经拥有它：

$ sudo apt-get install -y mcrypt php5-mcrypt

Check if mcrypt module is loaded:

检查 mcrypt 模块是否已加载：

$ php -m | grep mcrypt

if nothing shows, is because is not loaded, but you already have installed above right? So do this:

如果什么都不显示，是因为没有加载，但是你上面已经安装了对吗？所以这样做：

$ php5enmod mcrypt
$ sudo service apache2 restart

Check again and you should see mcrypt instead of nothing. Thats a good sign, reload you app and go fix your next error ;)

再次检查，您应该看到 mcrypt 而不是什么都没有。这是一个好兆头，重新加载您的应用程序并修复您的下一个错误；）

$ php -m | grep mcrypt
mcrypt

回答by Md Shahadat Hossain

write in console php artisan key:generate

写在控制台 php artisan key:generate

you will get message like: Application key [get 32 char key] set successfully.

你会收到这样的消息： Application key [get 32 char key] set successfully.

replace app key in config/app.phplike 'key' => env('APP_KEY', 'insert get 32 char key'),//line number 81

替换应用程序键config/app.php一样'key' => env('APP_KEY', 'insert get 32 char key'),//line number 81

回答by rüff0

if you are using app.php configuration file instead of reading key from .env file, then you can remove the env() function on key variable, ex:

如果您使用 app.php 配置文件而不是从 .env 文件中读取密钥，那么您可以删除密钥变量上的 env() 函数，例如：

'key' = env('someRandom36CharsString'),

to

到

'key' = 'someRandom36CharsString',
