Please help me what went wrong. Is anything need to add in composer.json?

Thanks

Hello Dhandapani,

To use a particular web framework, just add it to composer.json:

{

    "require": {

        "symfony/symfony": " ^3.0"

    }

}

In your case, this statement should refer to Codeigniter, not Symfony. 

There are quite a few references to Symfony in the error messages displayed during building. Did you attempt to install that framework? 

Is there any particular reason why you choose PHP 7.1 in your composer.json file? 

"require": {

 "php": "7.1.*"

 },

If you don't specify any version in composer.json, 7.2 gets installed. By default, the PHP runtime uses PHP 7.2, but you should explicitly declare your PHP version in the composer.json file to prevent your application from being automatically upgraded when a new version of PHP becomes available. 

You may benefit from more related detail, if you read the "Using PHP Libraries" documentation page.

Thanks George,

Before upgrade PHP 7.2, to use the latest version of PHP in GAE using like this.GAE Flexible environment Codeigniter worked fine.

"require": {

 "php": "7.1.*"

 },

Now it using PHP 7.2 by default.

To use a particular web framework, just add it to composer.json:

{

    "require": {

        "codeigniter/codeigniter": " ^3.1.6"

    }

}

I got issues. So I tried like this composer.json, I updated version php >=7.2.0

},

"require": {

"php": ">=7.2.0"

},

"suggest": {

"paragonie/random_compat": "Provides better randomness in PHP 5.x"

},

"require-dev": {

"mikey179/vfsStream": "1.1.*",

"phpunit/phpunit": "4.* || 5.*"

}

}

Now CodeIgniter builds successfully in GAE flexible environment.
