Zend OPcacheをロードできません-すでにロードされています

私はUbuntu 16.04を使用していますが、以下のコマンドでLAMP Stackをインストールしたかったのですが、

    Sudo apt-get autoremove --purge php5-*
    Sudo apt-get install python-software-properties
    Sudo add-apt-repository ppa:ondrej/php
    Sudo apt-get update
   Sudo apt-get -y install php7.1 php7.1-cli php7.1-common php7.1-dev
   Sudo apt-get -y install libapache2-mod-php7.1
   Sudo apt-get -y install php7.1-pgsql php7.1-mysql
   Sudo apt-get -y install php7.1-fpm php7.1-bz2 php7.1-json php7.1-phpdbg php7.1-intl php7.1-Gd php7.1-curl php7.1-mbstring php7.1-mcrypt php7.1-xdebug php7.1-xml php7.1-Zip
  Sudo apt-get -y install php-pear php-imagick php7.1-imap php-memcache php7.1-pspell php7.1-recode php7.1-sqlite3 php7.1-tidy php7.1-xmlrpc php7.1-xsl php-gettext

Apache2とphpは動作していますphp composer.phar installの実行に関する詳細は以下のエラーです

この問題は、composerのこの機能に関連しているようです https://github.com/composer/windows-setup/issues/58

動作させるためにxdebugを無効にすることができます。
