[SOLVED] File_put_contents(./composer.lock): Failed to open stream: Permission denied

Issue

I'm new to Ubuntu, and I'm trying to get my Ubuntu web server running, but I have a problem with composer. When I run composer install it outputs this error [ErrorException] file_put_contents(./composer.lock): Failed to open stream: Permission denied. I found a solution for this on the internet, but it doesn't work for me

Not working solution:

 sudo chown -R $USER ~/.composer/

It outputs

chown: cannot access '/home/admin/.composer/': No such file or directory

I'm using Ubuntu 20.04. Does anyone know what should I do?

Solution

composer install is trying to create a .composer.lock file in your project directory, so php should have permission to do that.

A quick hack is to use sudo composer install ,but this is not the recommended way.

this should also work

sudo chown -R :www-data /fullpath-to-your-project
