操作系统:Ubuntu 17.10
我安装了LAMPP和Laravel.当我尝试时,composer install我遇到了以下错误

  To enable extensions, verify that they are enabled in your .ini files:
    - /etc/php/7.1/cli/php.ini
    - /etc/php/7.1/cli/conf.d/10-opcache.ini
    - /etc/php/7.1/cli/conf.d/10-pdo.ini
    - /etc/php/7.1/cli/conf.d/20-calendar.ini
    - /etc/php/7.1/cli/conf.d/20-ctype.ini
    - /etc/php/7.1/cli/conf.d/20-exif.ini
    - /etc/php/7.1/cli/conf.d/20-fileinfo.ini
    - /etc/php/7.1/cli/conf.d/20-ftp.ini
    - /etc/php/7.1/cli/conf.d/20-gettext.ini
    - /etc/php/7.1/cli/conf.d/20-iconv.ini
    - /etc/php/7.1/cli/conf.d/20-json.ini
    - /etc/php/7.1/cli/conf.d/20-mbstring.ini
    - /etc/php/7.1/cli/conf.d/20-pdo.ini
    - /etc/php/7.1/cli/conf.d/20-phar.ini
    - /etc/php/7.1/cli/conf.d/20-posix.ini
    - /etc/php/7.1/cli/conf.d/20-readline.ini
    - /etc/php/7.1/cli/conf.d/20-shmop.ini
    - /etc/php/7.1/cli/conf.d/20-sockets.ini
    - /etc/php/7.1/cli/conf.d/20-sysvmsg.ini
    - /etc/php/7.1/cli/conf.d/20-sysvsem.ini
    - /etc/php/7.1/cli/conf.d/20-sysvshm.ini
    - /etc/php/7.1/cli/conf.d/20-tokenizer.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

我重新检查文件所有扩展都已启用,扩展名在 /usr/lib/php/20160303文件夹中.
