[php] Cannot create cache directory .. or directory is not writable. Proceeding without cache in Laravel

I created a new Laravel project. When I go to the terminal to install the dependecies composer displays the following warning:

Cannot create cache directory /home/w3cert/.composer/cache/repo/https---packagist.org/, or directory is not writable. Proceeding without cache.

Give full access of .composer to user.

sudo chown -R 'user-name' /home/'user-name'/.composer

or

sudo chmod 777 -R /home/'user-name'/.composer

user-name is your system user-name.

to get user-name type "whoami" in terminal:

Use this command:

sudo chown -R $USER ~/.composer/

When you installed composer pretty sure you used $ sudo command because of that the ~/.composer folder was created by the root.

Run this to fix the issue:

$ sudo chown -R $USER $HOME/.composer

I had the same problem today. Try it!

sudo chown -R  [yourgroup]  /home/[youruser]/.composer/cache/repo/https---packagist.org/


sudo chown -R  [yourgroup]   /home/[youruser]/.composer/cache/files/

I had a similar problem recently, and needed to change the permissions of my vendor folder

By running following commands :

1. php artisan cache:clear
2. chmod -R 777 storage vendor
3. composer dump-autoload

I need to give all the permissions required to open and write vendor files to solve this issue

Run this command :

    sudo chown -R yourUser /home/yourUser/.composer
