Answer 1

Best way to upgrade laravel framework for your projects in following steps

1. Take backup of your composer.json file
2. remove all third party packages from composer.json file or take latest composer.json from laravel git repository https://github.com/laravel/laravel
3. comment all third party packages service providers from app.php file (for version below Laravel 5.5)
4. Now run composer update command in terminal
5. Once Laravel update done. Now install all your third party packages again and enable third party service provider on app.php file.

update: if you are trying to upgrade laravel version 5.5 and up skip step 3. also for laravel 5.5 and up no need to enable third party package service providers in step 5.

Happy updating laravel for your projects.

Answer 2

You have to install these packages first before run composer update, also change the version of laravel to 5.7 in your composer.json file.

Ubundu Terminal Command

sudo apt install php7.2 libapache2-mod-php7.2 php7.2-mbstring php7.2-xmlrpc php7.2-soap php7.2-gd php7.2-xml php7.2-cli php7.2-zip

• PHP >= 7.1.3
• Ctype PHP Extension
• JSON PHP Extension
• BCMath PHP Extension

Delete the vendor folder and try composer update

Answer 3

it was because of this line

cartalyst/stripe-laravel v7.0.0 requires illuminate/support 5.5

thank you all for help...

i just update cartalyst packages and composer update its worked

conclusion : for update your laravel project remember to upgrade your 3rd party packages ..

Answer 4

php -v

if below 7 , maybe you have alias like

php7 -v

or

php72 -v

many servers use php aliases

Answer 5

只需在 composer.json 文件中将 laravel 更改为 5.7.* 并运行 composer install 命令
