Question

How to solve this issue.

Thanks.

Answer 1

In my composer.lock was wrong info about this and any other packages yet. I have revert my changes with composer.json / composer.lock and it works for me. You can try:

1. Clear the composer cache
2. Remove the vendors
3. Change in composer.json version of packages to static (e.g 1.2.0) to avoid update of them
4. Remove composer.lock
5. Start composer install. Then it should work correclty.

Answer 2

Make sure your vertex/module-tax shasum value in composer.lock equals to this:

"shasum": "5301f7a4d294cabcab3ae83e31fe5386c076520c"  

Or try to add this line in your composer.json

"replace": {
        "vertex/module-tax": "*"
},

Answer 3

It's trouble with vertex/module-tax. Add to replace this module in your file composer.json

   "replace": {
        "vertex/module-tax": "*"
},

after that need use:

composer update

after a successful update, install vertex/module-tax

composer require vertex/module-tax
composer update
