This article mainly introduces the "apt-get command installation of Composer and php version conflict how to do", in the daily operation, I believe that many people in the apt-get command installation of Composer and php version conflict how to do have doubts, editor access to all kinds of information, sort out a simple and easy to use method of operation, hope to answer the "apt-get command installation of Composer and php version conflict how to do" the doubt is helpful! Next, please follow the editor to study!

Today, I found that the / usr/bin/php version is different from the / usr/local/php/bin/php version, which was still fine before.

It was later found that apt-get install composer installed a php to / usr/bin/php by default to overwrite the previous version of PHP.

# php-vPHP 7.2.40. # / usr/local/php/bin/php-vPHP 7.2.19 (cli) (built: Jul 3 2019 02:01:24) (ZTS) Copyright (c) 1997-2018 The PHP GroupZend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies

Refer to du Niang, modify the PHP version of composer, and find that it still doesn't work.

Qing@qing-PC:~/Desktop$ composerPHP Warning: require (Composer/autoload.php): failed to open stream: No such file or directory in/ usr/bin/composer on line 9Warning: require (Composer/autoload.php): failed to open stream: No such file or directory in/ usr/bin/composer on line 9PHP Fatal error: require (): Failed opening required 'Composer/autoload.php' (include_path='.:/usr/local/php/lib/php') in/ usr/bin/composer on line 9Fatal Error: require (): Failed opening required 'Composer/autoload.php' (include_path='.:/usr/local/php/lib/php') in/ usr/bin/composer on line 9

The 'Composer/autoload.php' file can't be found in the / usr/local/php/lib/php directory at all.

Have no choice but to uninstall composer, delete the php version of composer automatic installation, delete phar and other composer-related files:

# apt-get remove composer# rm-rf / usr/bin/php# rm-rf / usr/bin/php7.2# rm-rf / usr/bin/phar*

Let's install composer through the official way.

# ln-s / usr/local/php/bin/php / usr/bin/php# wget https://getcomposer.org/installer# mv installer composer-setup.php# php composer-setup.php-- install-dir=/usr/bin/-- filename=composer# php/ usr/bin/composer

Check to see if the / usr/bin/php version is still overwritten.

# php-v

Or the php version created through a soft connection (ln-s / usr/local/php/bin/php / usr/bin/php)

Note that / usr/bin/php has not been overwritten.
