apt-get命令安裝的Composer，捆綁安裝的/usr/bin/php與/usr/local/php/bin/php版本衝突

後面發現是 apt-get install composer預設安裝了一個php到/usr/bin/php把之前的PHP版本覆蓋掉了……
# php -v
PHP 7.2.40 ......
#/usr/local/php/bin/php -v
PHP 7.2.19 (cli) (built: Jul 3 2019 02:01:24) ( ZTS )

參照度娘，修改composer 的PHP版本，發現還是不行……
qing@qing-PC:~/Desktop$ composer PHP Warning: require(Composer/autoload.php): failed to open stream: No such file or directory in /usr/bin/composer on line 9 <span style='color: #ff0000'> Warning: require(Composer/autoload.php): failed to open stream: No such file or directory in /usr/bin/composer on line 9 </span>PHP Fatal error: require(): Failed opening required 'Composer/autoload.php' (include_path='.:/usr/local/php/lib/php') in /usr/bin/composer on line 9 <span style='color: #ff0000'> Fatal error: require(): Failed opening required 'Composer/autoload.php' (include_path='.:/usr/local/php/lib/php') in /usr/bin/composer on line 9
/usr/local/php/lib/php 目錄下根本找不到 'Composer/autoload.php' 檔案……
無奈只能解除安裝composer，刪除composer自動安裝裝的php版本，刪除phar等composer相關檔案 :
# apt-get remove composer
# rm -rf /usr/bin/php
# rm -rf /usr/bin/php7.2
# rm -rf /usr/bin/phar*
還是通過官方的方式安裝composer吧……
# 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
檢視/usr/bin/php版本是否還是被覆蓋掉……
# php -v
還是通過軟連線建立的php版本（ln -s /usr/local/php/bin/php /usr/bin/php）
說明/usr/bin/php並沒有被覆蓋掉。
