Como criar um projeto laravel na pasta htdocs

Eu sou um desenvolvedor web. Criei projetos no sistema operacional Windows, mas agora mudei completamente para o Ubuntu 20.04. Eu instalei o PHP e o composer. Mas quando eu quero criar um projeto Laravel nele htdocsele cria um projeto mas vendorfalta uma pasta. Quando escrevo composer updatena CLI na htdocspasta, ele mostra estes erros:

1=>
Cannot create cache directory /home/saad/.cache/composer/repo/https---repo.packagist.org/, or directory is not writable. Proceeding without cache
Cannot create cache directory /home/saad/.cache/composer/files/, or directory is not writable. Proceeding without cache

2=>
PHP temp directory (/tmp) does not exist or is not writable to Composer. Set sys_temp_dir in your php.ini

3=>
Your requirements could not be resolved to an installable set of packages.

Então mostra estes:

Problem 1
    - laravel/framework v7.25.0 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.
    - laravel/framework v7.24.0 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.
    - laravel/framework 7.x-dev requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.
    - Installation request for laravel/framework ^7.24 -> satisfiable by laravel/framework[7.x-dev, v7.24.0, v7.25.0].

  To enable extensions, verify that they are enabled in your .ini files:
    - /etc/php/7.4/cli/php.ini
    - /etc/php/7.4/cli/conf.d/10-opcache.ini
    - /etc/php/7.4/cli/conf.d/10-pdo.ini
    - /etc/php/7.4/cli/conf.d/20-bcmath.ini
    - /etc/php/7.4/cli/conf.d/20-calendar.ini
    - /etc/php/7.4/cli/conf.d/20-ctype.ini
    - /etc/php/7.4/cli/conf.d/20-exif.ini
    - /etc/php/7.4/cli/conf.d/20-ffi.ini
    - /etc/php/7.4/cli/conf.d/20-fileinfo.ini
    - /etc/php/7.4/cli/conf.d/20-ftp.ini
    - /etc/php/7.4/cli/conf.d/20-gettext.ini
    - /etc/php/7.4/cli/conf.d/20-iconv.ini
    - /etc/php/7.4/cli/conf.d/20-json.ini
    - /etc/php/7.4/cli/conf.d/20-phar.ini
    - /etc/php/7.4/cli/conf.d/20-posix.ini
    - /etc/php/7.4/cli/conf.d/20-readline.ini
    - /etc/php/7.4/cli/conf.d/20-shmop.ini
    - /etc/php/7.4/cli/conf.d/20-sockets.ini
    - /etc/php/7.4/cli/conf.d/20-sysvmsg.ini
    - /etc/php/7.4/cli/conf.d/20-sysvsem.ini
    - /etc/php/7.4/cli/conf.d/20-sysvshm.ini
    - /etc/php/7.4/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.

Responder1

Você tem que entrar na pasta do projeto para rodar o compositor ...

exemplo:

cd path/to/htdocs/your-laravel-project-folder

Então corra

composer install

Responder2

Um de seus problemas é que você composernão tem permissão de gravação para arquivos /home/saad/.cache/composer/.

Outro problema é que está faltando o php-mbstringpacote. Instale-o por:

sudo apt install php7.4-mbstring
