composer:报错/usr/bin/env: ‘php’: No such file or directory

一，报错信息:

# composer --version
/usr/bin/env: ‘php’: No such file or directory

二，原因

php文件的路径未指定

]# php --version
-bash: php: command not found

三，解决:

 指定:

# vi /etc/profile

在末尾附加:

export PATH="/opt/software/php-7.3.6/bin:$PATH"

使生效:

# source /etc/profile

测试效果:

# php --version
PHP 7.3.6 (cli) (built: Jan 10 2026 10:43:09) ( NTS )

Zend Engine v3.4.0, Copyright (c) Zend Technologies

测试composer:

# composer --version
