Magento 2 Install via Composer error

Question

I am trying to install magento2 via composer using following command. My System specification is PHP Version 7.0.20-1~ubuntu16.04.1

composer create-project --repository-url=https://repo.magento.com/ magento/project-community-edition

I got the following error

Updating dependencies (including require-dev)

Your requirements could not be resolved to an installable set of packages.

Problem 1

- Installation request for magento/product-community-edition 2.1.7 -> satisfiable by magento/product-community-edition[2.1.7].
- magento/product-community-edition 2.1.7 requires php ~5.6.5|7.0.2|7.0.4|~7.0.6 -> your PHP version (7.1.6) does not satisfy that requirement.

Answer 1

Your error message already answered the question.

Magento 2 doesn't support PHP 7.1.x yet, please downgrade it to ~5.6.5|7.0.2|7.0.4|~7.0.6 There is a typo in DevDocs, if you need to know about the detail, please check this GitHub issue.

Good luck and welcome to Magento 2 :)

• Kishor Hase: I know that, but my PHP Version is 7.0.20-1 and this PHP version is in range of 7.0.2|7.0.4|~7.0.6
• Toan Nguyen: It said your PHP version (7.1.6), please notice that PHP CLI might use different version with your PHP FPM. I have 4 PHP version in my webserver too.
