How can I install mcrypt under PHP7? Laravel needs it

Had the same issue - PHP7 missing mcrypt.

This worked for me. When asked, keep local PHP configuration files.

sudo apt-get updatesudo apt-get install mcrypt php7.0-mcryptsudo apt-get upgrade

Restart FPM (or Apache or NGINX etc.) after installation.

php laravel laravel-4 php-7 mcrypt

I'm on Mac and with laravel valet I've solved with this:

brew install php70-mcrypt

php laravel laravel-4 php-7 mcrypt

Even if you enable mcrypt in php.ini, this issue may occur.Try the following steps.

sudo apt-get updatesudo apt-get install mcrypt php7.0-mcrypt

I am working in ubuntu 16.04 and the following commands also helped me.
