You should use php-cli to by-pass disable_functionstemporarily.
您应该使用 php-cli暂时绕过disable_functions。
php -d "disable_functions=" /path/to/composer install
回答by Antonio Carlos Ribeiro
Edit your php.inifile and search for the line
编辑您的php.ini文件并搜索该行
disable_functions = pcntl_alarm,pcntl_fork,pcntl_waitpid,pcntl_wait...
It should be disabled there and you must enabled it. This a security precaution.
它应该在那里被禁用，你必须启用它。这是一项安全预防措施。
