现在我试图用composer来安装我的PHP包,但是我收到了这个错误信息：
$composer安装

[Symfony\Component\Process\Exception\RuntimeException]
The Process class relies on proc_open,which is not available on your PHP installation.
编辑：
在启用proc_open函数后,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 Stack trace: #0 [internal function]: Composer\Util\ErrorHandler::handle(2,'proc_open(): fo...','phar:///usr/loc...',990,Array) #1 phar:///usr/local/bin/composer/vendor/symfony/console/Symfony/Component/Console/Application.PHP(990): proc_open('stty -a | grep ...',Array,NULL,Array) #2 phar:///usr/local/bin/composer/vendor/symfony/console/Symfony/Component/Console/Application.PHP(832): Symfony\Component\Console\Application->getSttyColumns() #3 phar:///usr/local/bin/composer/vendor/symfony/console/Symfony/Component/Console/Application.PHP(797): Symfony\Component\Console\Application->getTerminalDimensions() #4 phar:///usr/local/bin/composer/vendor/symfony/console/Symfony/Component/Console/Application.PHP(731): Symfony\Component\Console\Application->getTerminalWidth() #5 phar:///usr/local/bin/com in phar:///usr/local/bin/composer/vendor/symfony/console/Symfony/Component/Console/Application.PHP on line 990
