现在我正在尝试使用 composer 来安装我的 php 包，但我收到了这个错误消息：$ composer install

Loading composer repositories with package information
Installing dependencies (including require-dev)
  - Installing filp/whoops (1.0.7)
    Downloading: 100%          

[Symfony\Component\Process\Exception\RuntimeException]                                   
The Process class relies on proc_open, which is not available on your PHP installation.

编辑 ：

启用 proc_open 功能后，我收到此错误，并将我的 php memory_limit 设置为 384M ：

Fatal error: Uncaught exception 'ErrorException' with message 'proc_open(): fork failed - Cannot allocate memory' in phar:///usr/local/bin/composer/vendor/symfony/console/Symfony/Component/Console/Application.php:990

您应该使用 php-cli暂时绕过disable_functions 。

php -d "disable_functions=" /path/to/composer install

编辑您的php.ini文件并搜索该行

disable_functions = pcntl_alarm,pcntl_fork,pcntl_waitpid,pcntl_wait...

它应该在那里被禁用，您必须启用它。这是一个安全预防措施。
