Package operations: 54 installs, 0 updates, 0 removals Analyzed 435842 rules to resolve dependencies Analyzed 6622 packages to resolve dependencies Finished: success: 45, skipped: 0, failure: 0, total: 45 Furthermore composer does not seem to reflect real-time when after initiating for 20 seconds it outputs it run 0.35s and so on later. It took almost 200 seconds alone, though running it together with other libraries seemed at some times running almost for 12 minutes. However, it still did not help me, though I tried/noticed installing any other single library was considerably fast, so I went on investigating libraries one by one which could cause the bottle-neck.ġ) YES And I located it to be codeception, 'codeception/codeception': '2.4.0', Prior I tried every single solution mention in this question to this time. Grouping my experience with answers from here and from the linked in question.

What ultimately helps is usually using composer incrementally, requiring or removing only a single package at a time using composer require, composer remove command, also regards adding any 'non-dependency specific' setting, any library can be added/removed for the sake of it of updating/refreshing the composer.json lock cache configuration.

Edit: Conclusion: no solution listed here or generally seems to be bulletproof.
