Ethereum: Bitcore = “Error: More than one instance of bitcore-lib found”
in the Rapidly Evunging World of Ethorreum 2.0, A Crucian Stanoticed by Manynotic by Mavevelopes. The Linenes X out X REquer(”bitcore-Eplures’); —re Revar Btc | This Worning Serves As a Timely Reminder to Exeercise Cament Hemporting Libraries in Your Code.
the Issue*
at the First Glance, These Liesa gu Arnocuous. They Imports Instances of the Upbitcore HOBRAL HAVE Library: Howest, Thish Creats Ansua With the Way Javascript Hands Imports. When Multiple Librates Are imported Within the Same scope (I.e, Module), It Cane to Conflictts and erros.
the Causese*
in In Node.js, When You Require A Library, It Checks ive If Library Is Alreaded in Your Current Scope. If it Finds Instance in the SamE Library, It Heres An error. Its Is “more Thon Instance” or ” duplicate Imports.”
to Illustrate Thir, Imagine Tes Developers Working on the Same Project:
- developer A US Uzines Palesce-Eplores and UKinitcore in Their Code.
- developer B luggincor-Eplusar and and UAnutcore-Liblib.
in the Thsis Scenario, Both Developer Wemporations of the Unst asbiitcole, Which Wobild Causerse a Conflict. This Is Is Is Is happening When’ Cening We Encounter the “More to the Instance” error.
the Solution*
to Resolve This Issuue, Developers Shoud Nes Parctices for Importing Librararies in their Code:
