Ich bin Webentwickler. Ich habe Projekte im Windows-Betriebssystem erstellt, bin jetzt aber vollständig auf Ubuntu 20.04 umgestiegen. Ich habe PHP und installiert composer
. Aber wenn ich ein Laravel-Projekt erstellen möchte, htdocs
wird zwar ein Projekt erstellt, aber vendor
der Ordner fehlt. Wenn ich composer update
in der CLI in htdocs
den Ordner schreibe, werden diese Fehler angezeigt:
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.
Dann zeigt diese:
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].

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

You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
Antwort1
Sie müssen in den Projektordner gelangen, um Composer auszuführen ...
Beispiel:
cd path/to/htdocs/your-laravel-project-folder
Dann renne
composer install
Antwort2
Eines Ihrer Probleme ist, dass composer
Sie keine Schreibberechtigung für haben /home/saad/.cache/composer/
.
Ein weiteres Problem ist, dass Ihnen das Paket fehlt php-mbstring
. Installieren Sie es wie folgt:
sudo apt install php7.4-mbstring
