Rename .env.exampleto .envin your laravel root folder
在你的 Laravel 根文件夹中重命名.env.example为.env
回答by Peter
The .envfile is not yet present because you will first need to create and configure it.
该.env文件尚不存在，因为您首先需要创建和配置它。
Do the following
请执行下列操作
# Navigate to the correct folder
$ cd /var/www/laravel
# Copy the example file to make a .env file
$ cp .env.example .env
# Set the parameters
$ vi .env

Probably you missed your .envfile in laravel project folder.So make .env.exampleto .envfile. Also give the required database connection.
也许你错过了.env在laravel项目文件folder.So让.env.example到.env文件中。还要给出所需的数据库连接。
.envfile look like this: (Fill up with required database connection)
.env文件看起来像这样：（填写所需的数据库连接）
APP_ENV=local
APP_DEBUG=true
APP_KEY=SomeRandomString
APP_URL=http://localhost
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=homestead
DB_USERNAME=homestead
DB_PASSWORD=secret
CACHE_DRIVER=file
SESSION_DRIVER=file
QUEUE_DRIVER=sync

REDIS_PORT=6379
MAIL_DRIVER=smtp

You can create it & rerun the command.
您可以创建它并重新运行命令。
# cd /var/www/laravel
# cp .env.example .env //renames .env.example to .env
# php artisan key:generate
Application key set successfully.

If, like me, you didhave a .envfile, you may find it has permissions that are too tight to allow your current user to write to it (and by implication the php artisan command your current user is attempting to run). I had changed all my Laravel files to be owned by www-data:www-dataand made my current user a member of the www-datagroup, and was thus a little stumped by this error.
如果像我一样，你确实有一个.env文件，你可能会发现它的权限太紧，不允许你的当前用户写入它（暗示你当前用户试图运行的 php artisan 命令）。我已将我所有的 Laravel 文件更改为归www-data:www-data我所有，并使我当前的用户成为该www-data组的成员，因此这个错误有点难倒。
However, I soon realised that my .envfile has the following permissions:
但是，我很快意识到我的.env文件具有以下权限：
-rw-r--r--
-rw-r--r--
...meaning the user which owns the file gets read-write, but the group and world can only read. Since my current user is a member of the groupwww-data, it can only read, not write.
...意味着拥有文件的用户可以读写，但组和世界只能读取。由于我当前的用户是该组的成员www-data，因此它只能读取，不能写入。
(You can check your file permissions by doing $ ls -la)
（您可以通过执行检查您的文件权限$ ls -la）
If you have the same situation, you have two choices; loosen the file permissions on that file (with chmod) or use sudoto run your php artisan commands. I chose the latter, since this is a production server for me and I like the tight permissions.
如果你有同样的情况，你有两个选择；放宽对该文件的文件权限（使用chmod）或用于sudo运行您的 php artisan 命令。我选择了后者，因为这是我的生产服务器，我喜欢严格的权限。
