作曲家使用较新版本的 php

Question

How do i get composer to use a newer version of php i have installed? I have downloaded and am using php 5.4 in all my local servers but when i download composer it points to my mac's default #!/usr/local/bin/env version, which is 5.3.15. I tried editing the composer executable and change the php used but it broke the executable.

I'm trying to use composer to install Laravel and it is downloading the wrong version because of this.

This is what the top of my composer executable looks like but then there's a bunch of weird characters below.

#!/usr/bin/env php
<?php

Phar::mapPhar('composer.phar');
define('COMPOSER_DEV_WARNING_TIME', 1366931166);
require 'phar://composer.phar/bin/composer';

composer.json for laravel project

{
    "require": {
        "laravel/framework": "4.0.*@dev"
    },
    "autoload": {
        "classmap": [
            "app/commands",
            "app/controllers",
            "app/models",
            "app/database/migrations",
            "app/database/seeds",
            "app/tests/TestCase.php"
        ]
    },
    "scripts": {
        "post-update-cmd": "php artisan optimize"
    },
    "minimum-stability": "dev"
}

Answer 1

If you don't care for permanent settings, below command worked for me:

/Applications/MAMP/bin/php/php5.6.27/bin/php /usr/local/bin/composer install

Syntax is:

{PATH TO YOUR PHP VERSION} {PATH TO COMPOSER EXECUTABLE} {COMPOSER COMMAND}

To know the executable path: which {EXECUTABLE} can be very helpful. Ex: which composer gave below output which I used in command above:

/usr/local/bin/composer

Answer 2

i found the problem. I moved the composer.phar file to my /usr/local/bin/ directory and no matter what i did, it was always using 5.3.15. I deleted the executable from my bin and redownloaded the .phar and moved that to my projects root and ran "php composer.phar install" and it looks like that worked.

To clean things up i did the following:

I left composer.phar at the root of my user profile

/Users/davidadams/composer.phar

I then opened my .bash_profile and added the following alias

alias composer='/usr/local/php5/bin/php /Users/davidadams/composer.phar'

That way it's available to me globally and i can define which php version i want to use. Hopefully others will find this useful.

By default composer on *nix systems uses the PHP binary/executeable specified by the environment. You can see that in the first line which is the shebang :

#!/usr/bin/env php

You can tell the shell to bang against a more concrete PHP version instead, eg:

#!/usr/local/php5/bin/php

On Windows systems if you use the composer setup you can specify the PHP binary and the setup then will change the environment to match those needs. But you can as well easily rewrite the batchfile -or- configure the windows operating system to execute .phar files with the specific PHP binary.

Answer 4

sudo vim ~/.bash_profile

add

export PATH="/Applications/MAMP/bin/php/php7.3.1/bin:$PATH"

in the above path I have php 7.3.1 so change that to whatever path you have

then hit Esc then :wq
