在CentOS上安装Composer失败

我收到以下错误:

[ErrorException] preg_replace_callback():编译失败:断言后预期(？(偏移量为36)

不知道它意味着什么.

我在CentOS 5.10上也遇到了同样的错误.您应该尝试安装旧版本.版本1.0.0对我有用:

    php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
    php -r "if (hash_file('SHA384', 'composer-setup.php') === 'e115a8dc7871f15d853148a7fbac7da27d6c0030b848d9b3dc09e2a0388afed865e6a3d6b3c0fad45c48e2b5fc1196ae') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
    php composer-setup.php -- --version=1.0.0
    php -r "unlink('composer-setup.php');"
