Question

现在我正在尝试使用composer来安装我的php包，但是我收到了以下错误消息： $ 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函数后，我收到此错误并将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

Answer 1

你应该使用php-cli暂时绕过 disable_functions 。

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

Answer 2

修改您的php.ini文件并搜索

行

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

应该在那里禁用它，你必须启用它。这是一项安全预防措施。

laravel4 composer install得到proc_open不可用的错误
