I'm trying to clone a github repository and issue a composer install on it. But I am getting this:

Warning: The lock file is not up to date with the latest changes in composer.json. You may be getting outdated dependencies. Run update to update them.

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

    try `composer update` – Imanali Mamadiev Nov 14 '18 at 06:27
  • share the `require` sections of your `composer.json` – Peyman Mohamadpour Nov 14 '18 at 08:11
  • `symfony/symfony` includes `symfony/process` too. This leads to a conflict as a package cannot be installed in two versions. There was a bug in Composer that allowed this mistakenly in previous versions, but this bug was fixed in Composer 1.7.3. You now need to either remove the `symfony/process` dependency and stick with the Process component in version 3.4 or require all Symfony components explicitly if you need a newer version of the Process component (or update `symfony/symfony` to 4.1). – xabbuh Nov 14 '18 at 11:12
  • @Trix edited to include the require section – user6313136 Nov 14 '18 at 17:14
  • @ImanaliMamadiev I did run composer update and get similar errors – user6313136 Nov 14 '18 at 17:14
  • What's your `php` version? and Did try change php version in `composer.json`? – Imanali Mamadiev Nov 15 '18 at 03:54
  • Trix's answer worked for me. I had exact same problem. mark her/his answer as accepted to help others – biji buji Nov 18 '18 at 14:23

Run: composer update --lock to get your lock file in sync with your composer.json.

You may use depends & prohibits on composer to see what exactly you should do:

composer depends symfony/process 3.4.15

and

composer prohibits symfony/symfony 4

This two commands tell you what is the conflict and what you should do.

The main problem is that your composer.json and composer.lock are not in sync. The first file tells composer what are required package & their version constraints, and the second one shares the exact same package version between collaborators, for consistency.

If the repository owner does not help you with this problem, the only way you have is:

rm composer.lock
rm -rf vendor
composer install

This will remove vendor directory contents and install a fressh copy of all dependencies, according to just composer.json

share your comooser.json file please , i think you should update it : 

    "require": {
    "symfony/process": "3.4.*",
    "symfony/symfony": "3.4.*"
},

or

 "require": {
    "symfony/process": "4.1.*",
    "symfony/symfony": "4.1.*"
},

Solution was to download a previous version of composer (1.7.2) manually from the website and overwrite my 1.7.3 version.
