Answer 1

I faced this issue as well but in my case, I was in wrong directory. Check the directory you are working

Answer 2

I had this problem to install laravel/lumen.

It can be resolved with the following command:

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

Answer 3

In my case I don't have issues with ~/.composer.
So being inside Laravel app root folder, I did sudo chown -R $USER composer.lock and it was helpful.

Answer 4

I was getting the same exception, but in my case I am using PowerShell to run commands So, I fixed this with an instruction to unblock multiple files first. PS C:\> dir C:\executable_file_Path\*PowerShell* | Unblock-File and then use the following to load the package & 'C:\path_to_executable\php.exe' "c:\path_to_composer_.phar_file\composer.phar "require desired/package

Answer 5

To resolve this, you should open up a terminal window and type this command:

sudo chown -R user ~/.composer (with user being your current user, in your case, kramer65)

After you have ran this command, you should have permission to run your composer global require command.

You may also need to remove the .composer file from the current directory, to do this open up a terminal window and type this command:

sudo rm -rf .composer

Answer 6

In my case I used sudo mkdir projectFolder to create folder. It was owned by root user and I was logged in using non root user.

So I changed the folder permission using command sudo chown mynonrootuser:mynonrootuser projectFolder and then it worked fine.
