Upgrade Laravel version from 5.2.45 to 5.4

I am working on an existing application and the application is in laravel framework(version 5.2.45).And now i have to upgrade it to the version(5.4).I have follow the upgrade version step from laravel official documentation. Below is the steps which i have done :

1) Update the version number in laravel composer.json file in "laravel/framework" key.

2) Then after run the command composer update.

3) After that during executing the command i face error and the solution of that is to add the below line in composer.json file.

"minimum-stability": "dev",
"prefer-stable": true,

4) Then after again i execute the command composer update.Now i am facing the issue which i have attached in the below image :

Here is the code of composer.json file :
