Error when using composer

[brasileric]

Hi, It looks so simple, so installed Composer without problems, but now when I want to install Omnipay by Composer I get this error:

$ php composer.phar install Loading composer repositories with package information file_put_contents(/home/hericadmin/.composer/cache/repo/https---packagist.org/packages.json): failed to open stream: Permission denied https://packagist.org could not be fully loaded, package information was loaded from the local cache and may be out of date Installing dependencies (including require-dev)

[Composer\Repository\RepositorySecurityException] The contents of http://packagist.org/p/omnipay/2checkout$9483edd00d6d9c3fc7ca6c3e4cb1a6b290c4f4d37ef4f01fdb41e33a24404d29.json do not match its signature. This should indicate a man-in-the-mid dle attack. Try running composer again and report this if you think it is a mistake.

Is the /home/hericadmin/.composer directory or its cache subdirectory not owned by your user?

[brasileric]

not owned by user, I didn't choose this directory

[brasileric]

well, I fixed by giving this cache folder writing rights.

@brasileric how to do that please!

@brasileric THANK YOU!!

@mohsenuss91 see this for the cache dir: https://getcomposer.org/doc/06-config.md#cache-dir

in my case simply chown the cache dir

@mohsenuss91 I used this command for the cache folder: sudo chmod -R a+rw /home/USERNAME_HERE/.composer/cache

@AleksandarSavic95 for current user: sudo chmod -R a+rw ~/.composer/cache
