  To enable extensions, verify that they are enabled in your .ini files:
    - /etc/php/7.0/cli/php.ini
    - /etc/php/7.0/cli/conf.d/10-mysqlnd.ini
    - /etc/php/7.0/cli/conf.d/10-opcache.ini
    - /etc/php/7.0/cli/conf.d/10-pdo.ini
    - /etc/php/7.0/cli/conf.d/20-calendar.ini
    - /etc/php/7.0/cli/conf.d/20-ctype.ini
    - /etc/php/7.0/cli/conf.d/20-exif.ini
    - /etc/php/7.0/cli/conf.d/20-fileinfo.ini
    - /etc/php/7.0/cli/conf.d/20-ftp.ini

    - /etc/php/7.0/cli/conf.d/20-posix.ini
    - /etc/php/7.0/cli/conf.d/20-readline.ini
    - /etc/php/7.0/cli/conf.d/20-shmop.ini
    - /etc/php/7.0/cli/conf.d/20-sockets.ini
    - /etc/php/7.0/cli/conf.d/20-sysvmsg.ini
    - /etc/php/7.0/cli/conf.d/20-sysvsem.ini
    - /etc/php/7.0/cli/conf.d/20-sysvshm.ini
    - /etc/php/7.0/cli/conf.d/20-tokenizer.ini
    - /etc/php/7.0/cli/conf.d/20-zip.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

我有什么办法解决这个问题？

【参考方案1】：

安装所需的mbstring扩展

sudo apt-get install php-mbstring 

在 Dockerfile 中你应该添加：

RUN docker-php-ext-install mbstring

【讨论】：

这次是phpunit/phpunit 6.5.7 requires ext-dom -> ...

需要什么？剩下的句子？

用phpunit/phpunit 6.5.7 requires ext-dom替换laravel/framework v5.5.1 requires ext-mbstring

但我使用了sudo apt-get install php7.0-xml，现在它工作得很好。但是由于某种原因，即使在我使用sudo apt-get install php-mbstring 之前它也不起作用。但我认为是我安装了 laravel 5.5.*（需要 php >= 7.1.3）并且我安装了 7.0.1。

感谢您为我解决问题。

【参考方案2】：

sudo apt install php-mbstring 将工作，并将下载最新 PHP 版本的插件。

如果您的 PHP 版本不是最新的，那么您可以在其中添加版本：

# PHP 7.1
sudo apt install php7.1-mbstring

# PHP 7.2:
sudo apt install php7.2-mbstring

# PHP 7.3
sudo apt install php7.3-mbstring

# PHP7.4
sudo apt install php-mbstring

【讨论】：

就我而言，我同时拥有 php8.0 和 php7.4，但我已将系统配置为使用 php8.0。当我运行sudo apt install php-mbstring 时，会为 php.0 安装 php-mbstring。为了得到它的php7.4，我做了sudo apt install php7.3-mbstring，问题就解决了。

就我而言，对于 php8.1，php8.1-mbstring 作为最新的可能命名不起作用，但 php-mbstring 起作用。这与你在这里写的一致：最新的php版本只是php-，只有以前的版本可以修复。

我在安装 Laravel 6 时遇到了同样的问题并收到这样的错误

    - /etc/php/7.4/cli/php.ini
    - /etc/php/7.4/cli/conf.d/10-mysqlnd.ini
    - /etc/php/7.4/cli/conf.d/10-opcache.ini

    - /etc/php/7.4/cli/conf.d/20-tokenizer.ini
    - /etc/php/7.4/cli/conf.d/20-zip.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

然后我尝试命令：

sudo apt-get install php-mbstring 

之后我再次尝试安装laravel，仍然出现这样的问题

    Installing laravel/laravel (v6.12.0)
  - Installing laravel/laravel (v6.12.0): Loading from cache
Created project in sistemLogin
> @php -r "file_exists('.env') || copy('.env.example', '.env');"
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - phpunit/phpunit 8.5.x-dev requires ext-dom * -> the requested PHP extension dom is missing from your system.
    - phpunit/phpunit 8.5.2 requires ext-dom * -> the requested PHP extension dom is missing from your system.
    - phpunit/phpunit 8.5.1 requires ext-dom * -> the requested PHP extension dom is missing from your system.
    - phpunit/phpunit 8.5.0 requires ext-dom * -> the requested PHP extension dom is missing from your system.
    ...........

所以如果这样的话，你可以试试命令

sudo apt-get update
sudo apt install php-xml

然后运行

composer update
composer require cviebrock/eloquent-sluggable

PHP7 : install ext-dom issue

【参考方案4】：

我用这个解决了我的问题：sudo apt-get install php-mbstring
