Problems installing Phalcon3 on Ubuntu 14.04 with PHP7

I've gotten past a few hurdles, but can't seem to get over this one.

I have phalcon installed and enabled. phpinfo() reads:

under "Additional .ini files parsed": /etc/php/7.0/apache2/conf.d/30-phalcon.ini

phalcon also shows up running get_loaded_extensions(); [41] => phalcon

The problem I'm facing now is I can't composer install/update. Here is my composer.json file:

     {
        "require": {
            "php" : ">=7.0.0",
            "ext-phalcon" : ">=3.0.0"
        }
    }

The error I get when running composer install and/or update is:

Your requirements could not be resolved to an installable set of packages.

Problem 1 The requested PHP extension ext-phalcon >=3.0.0 is missing from your system. Install or enable PHP's phalcon extension.

I've also changed "ext-phalcon" to "phalcon" with the same results.

Hi

Try 

"ext-phalcon" : ">=3.0.x"

OR

"ext-phalcon" : ">=3.0.*"

[UnexpectedValueException] Could not parse version constraint >=3.0.x: Invalid version string "3.0.x"

and

[UnexpectedValueException] Could not parse version constraint >=3.0.: Invalid version string "3.0."

"ext-phalcon": "^3.0"

I'm not at work anymore and I haven't tried this suggestion, but I don't think it will work. It seems like Composer can't find the phalcon extension and I'm not sure why. phpinfo() shows it's there and enabled. Anyway, I'll try the ^3.0 value and see if it works. Weird problem though... I don't get it & the google usually solves most of my issues, but not this one.

i guess php -v says php5

ll /etc/alternatives/ | grep "php"

you can see there isphp -> /usr/bin/php or whatever i dont remember the exact path.

you need to change this to your php7 executable. for me is 

php -> /opt/php-7004/bin/php*

2 ways you can do that, by using $PATH in you .bashrc or

cd /etc/alternatives;
rm php;
ln -s /opt/php-7004/bin/php /etc/alternatives/php

in the last command this is my path, you need to say the full path to yours.

YOu can google $PATH ubuntu if you are not familiar ( i also havent try it , but it should work )

in reply to Zach 
php -version | head -1

Here is a switch to 7.0 then back to 5.5

if you get PHP 5.5.x, make this command:

update-alternatives --set php $(sudo update-alternatives --list php | grep "php7.0")

"ext-phalcon":"^3.0"

Problem 1

Ran the command: php -version | head -1

I see this: PHP 7.0.10-1+deb.sury.org~trusty+1 (cli) ( NTS )

Ran the command: update-alternatives --set php $(sudo update-alternatives --list php | grep "php7.0") command

Ran the command: ll /etc/alternatives/ | grep "php"

Now I see this:

Ran composer update and am still getting:

Problem 1

Thinking I'm going to give up on PHP7 for now... Need to get this dev environment running. :(

Ha, I did give up and it took me all of 3 hours to build a new vagrant VM, install Phalcon 3 and get my hello world working. It's not necessary to be on PHP7 and judging from how little support there is for it, I'm not super keen on using it for an enterprise production environment right now.

I appreciate the help, nonetheless... From everyone.
