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.
I have rechecked the files, all extensions are enabled and they are located in
/usr/lib/php/20160303folder.
我重新检查了文件，启用了所有扩展名，并且它们位于
/usr/lib/php/20160303文件夹中。

As the log speaks we need to install the extension dom. This is how we do it:
正如日志所说，我们需要安装扩展 dom。这是我们的做法：
sudo apt install php7.1-dom
If the log shows only one extension missing, than above command works. If there are other extension missing, you can add those extension in the same line like shown below:
如果日志仅显示缺少一个扩展名，则上述命令有效。如果缺少其他扩展名，您可以在同一行中添加这些扩展名，如下所示：
sudo apt install php7.1-dom php7.1-ext-mbstring
That's it. Now you won't have any issues in installing composer. Enter composer install
就是这样。现在您在安装 composer 时不会有任何问题。输入作曲家安装
