Composer Update - Your requirements could not be resolved to an installable set of packages

Question

I am having a horrible problem figuring this out. I have a php project and am trying to use composer to update the project (code was give to me to update, i am not the original developer). I run the update and get this:

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

  Problem 1
    - suncat/mobile-detect-bundle dev-master requires mobiledetect/mobiledetectl
ib 2.7.* -> no matching package found.
    - suncat/mobile-detect-bundle dev-master requires mobiledetect/mobiledetectl
ib 2.7.* -> no matching package found.
    - Installation request for suncat/mobile-detect-bundle dev-master -> satisfi
able by suncat/mobile-detect-bundle[dev-master].

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your min
imum-stability setting

or more details.

 problems.

my Composer.json contains this:

Answer 1

I got the same probleme ^^

Source : https://packagist.org/packages/suncat/mobile-detect-bundle

Change :

"mobiledetect/mobiledetectlib" : "dev-master",

To :

"mobiledetect/mobiledetectlib" : "2.7.*",

:)
