I'm told to update composer and then I get an error.

So when I run the 'composer' command in my terminal, I'm told:

Warning: This development build of composer is over 30 days old. It is recommended to update it by running "/usr/local/bin/composer self-update" to get the latest version.

So I ran this command:

vagrant@homestead:~/Sites$ /usr/local/bin/composer self-update

And then got this:

[Composer\Downloader\FilesystemException] Filesystem exception: Composer update failed: the "/usr/local/bin/composer" file could not be written

self-update [-r|--rollback] [--clean-backups] [version]

What should I do please?

Hi Jenny,

Simply run the command as sudo and composer will update without any issues.

sudo /usr/local/bin/composer self-update

Hope that helps.

Hi Jenny,

That's just a warning, so you should feel free to ignore it; all the composer commands you need to run for the course should work just fine.

Even so, thanks for the heads up on the warning message, we'll get that updated and ship out an update sometime soon.

Cheers!

Nathan
