Upgrading Laravel 5.4 to latest version (5.7)

问题

I am working on Laravel 5.4 with PHP version 5.6.4. My goal is to upgrade my project to Laravel 5.7 with PHP 7.1.

Now my question is: Do I have to upgrade to 5.5 > 5.6 > 5.7 or can I go directly from 5.4 to 5.7?

回答1:

There are some articles on documentation. You can upgrade to 5.7 directly but be sure to modify critical sections from this links 5.5->5.6, 5.6->5.7. And make a backup of current project first

回答2:

Better to upgrade 5.5 first an then go with 5.6 and 5.7 because if you see in 5.5 and 5.6 upgrade guide there are some packages also need to upgrade so you better go with the step by step.

5.4 to 5.5
5.5 to 5.6
5.6 to 5.7

For older versions, you can look at

5.3 to 5.4
4.2 to 5.3

回答3:

From my point of view, it would help to upgrade step by step. This helps to to see whether your application is already compatible with all changes that need to be made.

If you upgrade to 5.7 directly and face larger problems due to the changes, your quickest option is to downgrade to 5.4 again.

If you upgrade to 5.5 in the first step, you can make your application compatible to 5.5, test it thoroughly, deploy it, and start to test what needs to be done for the upgrade to 5.6.

Just update your laravel/framework dependency to 5.7.* in your composer.json file:

"require": {
    "php": "^7.1.3",
    "fideloper/proxy": "^4.0",
    "laravel/framework": "5.7.*",
    "laravel/tinker": "^1.0"
},

After, run this command on your command prompt: composer update

You will achieve success and your Larvael will change to version 5.7, more details are available on upgrade guide

回答5:

No,you sholud not upgrade step by step, only you can do this : https://laravel.com/docs/5.7/upgrade

回答6:

Just update your laravel/framework dependency to 5.7.* in your composer.json file. Since you are upgrading from 5.4 to 5.7, then you can easily just run

composer update

And if you modified some of Laravel's Traits or Methods in your 5.4 application, then you can check here for more info

You can just update your laravel/framework dependency to 5.7.* in your composer.json file.

1. change in composer.json:

From:

"require": {
        "php": ">=7.0.0",
        "fideloper/proxy": "~3.3",
        "laravel/framework": "5.4.*",
        "laravel/tinker": "~1.0"
    },

To:

"require": {
        "php": ">=7.1.3",
        "fideloper/proxy": "~4.0",
        "laravel/framework": "5.6.*",
        "laravel/tinker": "~1.0"
    },

2. Replace app\Http\Middleware\TrustedProxies.php file with contents below:

<?php

namespace App\Http\Middleware;

use Illuminate\Http\Request;
use Fideloper\Proxy\TrustProxies as Middleware;

class TrustProxies extends Middleware
{
    /**
     * The trusted proxies for this application.
     *
     * @var array
     */
    protected $proxies;

    /**
     * The headers that should be used to detect proxies.
     *
     * @var string
     */
    protected $headers = Request::HEADER_X_FORWARDED_ALL;
}

3. composer update

composer update

回答8:

For updating Laravel 6.x (Which means any subversions to V6)
Just run this command

cd [laravel installation directory]
composer update

You must have composer installed on your VM or PC.

For Linux users only:

Composer directory must be owned by current user

//Check ownership
ls -la ~/ | grep ".composer"

//If you don't own the directory
chown -R [user]/[user] ~/.composer
