Laravel First lesson: Laravel Download and install

Local installation laravel,php environment to be configured, it is recommended to xmapp a key to build.

1, the package directly from the official download, the official open source address: https://GitHub. Com/laravel/laravel (also available from this website: http://www.golaravel.com/download/ Download the one-click installation package and download it to see the page, which is not discussed here.

2, the unpacked folder to place the local environment directory, access to http://localhost/laravel/is inaccessible, laravel the starting page in the public directory, access to the following address to start.

http://localhost/laravel/public/, unfortunately, the error, such as, means that did not find the vendor directory autoload.php directory. Of course you can't find this file, because there is no.

3, next need to install composer (self-installation bar), run the command line, go to the Laravel directory, enter

Composer Install

commands, such as:

Wait for the installation to complete, the Wendor directory appears in the Laravel folder.

4, you find that you still cannot access, appeared two lines big "whoops, looks like something went wrong." This is because we did not turn on debug, so we do not see the error prompt.

Open the app.php of the Laravel\config directory, modify

' Debug ' = env (' App_debug ', false), for ' debug ' = ' env ' (' App_debug ', true),

We see the error message: ' No supported Encrypter found. The cipher and/or key length is invalid.

Don't worry, it's because we don't have the. env file configured. Locate the. Env.example in the Laravel directory to rename it. Env. If you are a window system, a hint will pop up

The workaround is simple: Save with Notepad and rename.

It is still inaccessible because the. Env App_key is not set. At the command line, enter:

PHP Artisan Key:generate

The. env file will automatically generate App_key, and the lazy way is to randomly engage a 32-character.

See the 'Laravel 5' in the characters to show that the installation was successful.
