如何解决作曲家中的依赖版本冲突？

Question

I am currently developing a Laravel application which has following package requirements in composer.json

"phpunit/phpunit": "~5.7",
"phpspec/phpspec": "2.5.*",
"sebastian/exporter": "~2.0"

Now, problem is that phpunit requires exporter 2.0 and the package phpspec requires exporter 1.0.

So, now these requirements are conflicting and I am unable to update the packages.

How should I resolve this conflict and install these packages?

Note: I noticed that from the composer.json of phpspec that it has requirements defined as ~1.0|~2.0 for exporter. So it should work with both but it doesn't seem to be working.

Answer 1

In order to have a phpspec version that supports sebastian/exporter 2.x, you have to use 3.2.2 or higher.
