What to do if 500 error occurs during new laravel installation

[Preface]

In the process of using Laravel for development, we often encounter various (seemingly) weird problems, such as the 500 error we encountered when laravel was newly installed today. This article will explain the causes of this error and provide some solutions.

[Problem Description]

When using Composer to install Laravel, some people will encounter a 500 error. This error is not an error in the program itself, but an error page returned by the server. Similar to the following:

[Cause Analysis]

Usually, this problem is not caused by Laravel itself. This problem is usually caused by incompatibilities in PHP versions. When you use Composer for a new installation of Laravel, it runs a PHP script on the server whose purpose is to download and install Laravel. This script has a minimum PHP version requirement. If the PHP version running on your server is lower than this requirement, a 500 error will occur.

[Solution]

1. Check the PHP version

First, check the PHP version running on your server. You can check using the following command:

php -v

If your PHP version is lower than the minimum version required by Laravel, then you need to upgrade your PHP version.

2. Upgrade the PHP version

To upgrade the PHP version, you need to master some server management skills. Depending on your server type and operating system, you can find relevant tutorials online.

For example, if you are using Ubuntu 16.04, run the following command in the console to upgrade the PHP version:

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get install php7.x

The above script will install the latest available PHP version. The 7.x here represents the latest PHP 7 version. If you want to install the PHP 5 version, replace 7.x with 5.x.

3. Retry the new installation of Laravel

After upgrading the PHP version, you can try the new installation of Laravel again. This time you should be able to avoid the 500 error problem.

[Summary]

The 500 error encountered when Laravel is newly installed is usually caused by incompatible PHP versions. To solve this problem, you need to check whether the PHP version in the server meets Laravel's requirements and upgrade it. I hope this article can help you solve this problem and make your Laravel journey more enjoyable.
