Can't install laravel installer via composer

Question 1

I'm trying to install laravel installer with the composer on my Ubuntu PC, but I get this error during the installation. `Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - laravel/installer v1.4.1 requires ext-zip * -> the requested PHP extension zip is missing from your system.
    - laravel/installer v1.4.0 requires ext-zip * -> the requested PHP extension zip is missing from your system.
    - Installation request for laravel/installer ^1.4 -> satisfiable by laravel/installer[v1.4.0, v1.4.1].

  To enable extensions, verify that they are enabled in those .ini files:
    - /etc/php/7.0/cli/php.ini
    - /etc/php/7.0/cli/conf.d/10-opcache.ini
    - /etc/php/7.0/cli/conf.d/10-pdo.ini
    - /etc/php/7.0/cli/conf.d/20-calendar.ini
    - /etc/php/7.0/cli/conf.d/20-ctype.ini
    - /etc/php/7.0/cli/conf.d/20-exif.ini
    - /etc/php/7.0/cli/conf.d/20-fileinfo.ini
    - /etc/php/7.0/cli/conf.d/20-ftp.ini
    - /etc/php/7.0/cli/conf.d/20-gettext.ini
    - /etc/php/7.0/cli/conf.d/20-iconv.ini
    - /etc/php/7.0/cli/conf.d/20-json.ini
    - /etc/php/7.0/cli/conf.d/20-phar.ini
    - /etc/php/7.0/cli/conf.d/20-posix.ini
    - /etc/php/7.0/cli/conf.d/20-readline.ini
    - /etc/php/7.0/cli/conf.d/20-shmop.ini
    - /etc/php/7.0/cli/conf.d/20-sockets.ini
    - /etc/php/7.0/cli/conf.d/20-sysvmsg.ini
    - /etc/php/7.0/cli/conf.d/20-sysvsem.ini
    - /etc/php/7.0/cli/conf.d/20-sysvshm.ini
    - /etc/php/7.0/cli/conf.d/20-tokenizer.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
`

The error appears then I use this comment:

composer global require "laravel/installer"

Question 2

It says that it requires zip extension

laravel/installer v1.4.0 requires ext-zip...

Install using (to install the default version):

sudo apt install php-zip

Or, if you're running a specific version of PHP:

# For php v7.0
sudo apt-get install php7.0-zip

# For php v7.1
sudo apt-get install php7.1-zip

# For php v7.2
sudo apt-get install php7.2-zip

# For php v7.3
sudo apt-get install php7.3-zip

# For php v7.4
sudo apt-get install php7.4-zip

Question 3

The solution:

Sometimes when you change your .env, the configs don't refresh without clear cache or restarting the server.

The error message are:

SQLSTATE[HY000] [1045] Access denied for user 'forge'@'localhost' (using password: YES)

The database are trying to get the information from the "cached" .env configuration, you should try:

php artisan config:clear

if not solve, restart your server.

[Edit] Another NON RECOMMENDED option:

Go to your configdatabase.php
remove the .env configuration

And set your own credentials

'mysql' => [
            'host' => '45.55.88.77',
            'database' => 'prod',
            'username' => 'forge',
            'password' => '*********',
        ],

Question 4

Try using composer update. That is what it says in the error.

...You may be getting outdated dependencies. Run update to update them...

Update:

Composer is trying to find the folder app/controllers/admin which is no standard folder in laravel. Are you sure this folder exists? If not, you could try removing these, and other custom folders, from the composer.json, and add them manually. You could also create the directories and leave the composer.json untouched.

Question 5

If you really wanted to, you could do all the work that Composer does manually, but you definitely should not. Installing Composer is easy, it's just a matter of getting the composer.phar file and running commands on it.

You do not need to run Composer on your server as well as locally, once you run composer install or composer update your project will have all its dependencies available and you can just upload it straight to your server.

Question 6

First of all,

Find your php.ini file in your system using $ php -i |grep php.ini command OR click where can I find the php.ini for php-cli.
Open php.ini file.
And, make sure these lines are present or not.

a) extension=mysql.so b)extension=pdo_mysql.so
If Yes, remove (;) this before them.
If not present, run this command sudo apt-get install php5-mysql

Now, type php artisan migrate command. I'm sure you will get error

can't connect to local MYSQL server through socket

Now,

Change bind-address from localhost to 127.0.0.1
Run /opt/lampp/bin/php.
After running this if you get

"unable to load dynamic library"

Then, remove php_mssql.dll extension (for non-windows)

If not getting error, come directly to Project-Name-Folder/config/database.php file and add this code 'unix_socket' => '/opt/lampp/var/mysql/mysql.sock',

Find the complete path of mysql.sock, and add it

'mysql' => [
    'driver'    => 'mysql',
    'host'      => env('DB_HOST', 'localhost'),
    'database'  => env('DB_DATABASE', 'danishLara'),
    'username'  => env('DB_USERNAME', 'root'),
    'password'  => env('DB_PASSWORD', ''),
    'unix_socket'   => '/opt/lampp/var/mysql/mysql.sock', //Add this line here
    'charset'   => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix'    => '',
    'strict'    => false,
],
