php - Magento2 Composer 要求包似乎不起作用

Question

在命令行上 -
我正在使用这个命令:

/opt/cpanel/composer/bin/composer require apptrian/image-optimizer:2.2.0

之后我在屏幕上看到了这个:

Warning: Composer should be invoked via the CLI version of PHP, not the cgi-fcgi SAPI
Do not run Composer as root/super user! See https://getcomposer.org/root for details
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Nothing to install or update
Generating autoload files

但是当我实际检查 composer.json 文件时，我没有看到任何变化。
并运行 composer update 我得到:

[root@s132-148-137-252 public_html]# /opt/cpanel/composer/bin/composer update
X-Powered-By: PHP/7.0.31
Content-type: text/html; charset=UTF-8

当我检查 php -v 使用

/opt/cpanel/ea-php70/root/usr/bin/php -v

我明白了

PHP 7.0.31 (cli) (built: Jul 23 2018 21:29:04) ( NTS )

    with Zend OPcache v7.0.31, Copyright (c) 1999-2017, by Zend Technologies

但如果我只检查 php -v

然后我得到 - 它返回时不正确 - (cgi-fcgi)

ea-php-cli Copyright 2017 cPanel, Inc.

如何纠正让 Composer 工作的问题以及 php-cli问题。

Answer 1

看起来您的服务器配置不正确，并且正在使用 SAPI PHP 进行 CLI 调用。您应该明确地使用 PHP for CLI 运行 Composer:

/opt/cpanel/ea-php70/root/usr/bin/php /opt/cpanel/composer/bin/composer require apptrian/image-optimizer:2.2.0

顺便说一句:您应该认真对待以 root 身份运行 composer 的警告——这可能会产生安全问题。
