cant update laravel 5.4 to 5.8

Question

Laravel/framework v5.8.12 requires PHP ^7.1.3 -> your PHP version (5.6.40) does not satisfy that requirement.

But my PHP version in wamp is 7.2.18

Answer 1

Seems you are using windows so from your terminal check your PHP version it should be 5.8.12

As you are using windows pc please following instructions --

• Right-click on My Computer and select properties or access following the path.

  Control Panel\System and Security\System

• In that window on the left side, you will see

  Advanced system settings

• Clicking on Advanced system settings will open a new window called System Properties.

• In that new window, you will see Environment Variable click there, then another new window will open.

• In that Environment Variables window, you will see two sections one is User variables for User(user pc name) and System variables

• Under the System variables section look for Path. Check below image

• Now click edit button which will open another window called Edit environment variable something like below image

• Now click add new and then in the input box you must paste the directory where php.ini exist.
• Now apply and save all the window
• Finally restart your pc.
• Now open your terminal and type php -v you will see your desired version. Now you can update your Laravel version.
• If it's not working but your version is ok then reinstall your composer and try again hope that will solve your issue

NT: You can see in my PC I'm using multiple version of PHP but when I type php -v in my terminal it shows 7.2.10. That because of my 7.2.10 having an upper position than 5.6 and you can change that. If you are having some kind of information you can try these steps
