composer install

[dbrekelmans]

I ran into a problem when executing composer install.

The message I get is:

Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Your requirements could not be resolved to an installable set of packages.

Problem 1

• The requested PHP extension ext-intl * is missing from your system.

To me it seems like there is a piece of software missing from the virtual machine, but I don't know if it's because I've done something wrong (as far as I can tell, I followed your exact instructions from the README).

Strange. This is the package php5-intl that is installed with the boostrap. Try destroying your vagrant box and trying to up again. If the problem persists, please let me know.

I have the same problem but it seems the correct modules are installed so I'm not sure why it's happening? Did anyone come up with a solution?

[niketkanoi]

I was able to resolve by installing all those missing extensions manually one by one. Magento 2 is up and running now.
