為什么安裝composer總是失敗，提示缺少phar?

參數(shù)：

Configure Command =>  './configure'  '--prefix=/usr/local/php7' '--with-config-file-path=/usr/local/php7/etc' '--enable-fpm' '--with-fpm-user=www' '--with-fpm-group=www' '--with-mysqli' '--with-pdo-mysql' '--with-iconv-dir' '--with-freetype-dir' '--with-jpeg-dir' '--with-png-dir' '--with-zlib' '--with-libxml-dir=/usr' '--enable-xml' '--disable-rpath' '--enable-bcmath' '--enable-shmop' '--enable-sysvsem' '--enable-inline-optimization' '--with-curl' '--enable-mbregex' '--enable-mbstring' '--with-mcrypt' '--enable-ftp' '--with-gd' '--enable-gd-native-ttf' '--with-openssl' '--with-mhash' '--enable-pcntl' '--enable-sockets' '--with-xmlrpc' '--enable-zip' '--enable-soap' '--without-pear' '--disable-phar' '--with-gettext' '--disable-fileinfo' '--enable-maintainer-zts'

[root@bogon php-7.1.11]# curl -sS https://getcomposer.org/installer | php
Some settings on your machine make Composer unable to work properly.
Make sure that you fix the issues listed below and run this script again:

The phar extension is missing.
Install it or recompile php without --disable-phar

明明已經(jīng)添加過了 --disable-phar 參數(shù)了，用 php -m 查看沒有這個(gè)模塊的？如何解決？
