Web3.js: npm install error - installing [email protected] in windows 10

[AhmedAdelFahmyHassanIbrahim]

Currently I am using [email protected] and I can't use the promises to retrieve a list of unlocked accounts created by Ganache

I installed web3 by using npm by writing npm install web3, as written in the documentation of web3, but it installed web3 0.19.1

these are some snippets

Hi @AhmedAdelFahmyHassanIbrahim. Have you checked out this similar issue? https://github.com/ethereum/web3.js/issues/1783#issuecomment-405650471

@nivida pasted a pretty detailed step by step guide to solving the installation issues on windows. Could you try that out and let me know if it solves your problem?

Hi @AhmedAdelFahmyHassanIbrahim, I am on windows aswell but I could not reproduce your issue.
I typed : npm install web3 then npm list web3
I have this output : [email protected]

I used Windows Powershell to install (if it can helps you).

Maybe this workaround can fix your error:

• Change your package.json dependencies web3 to "latest"
• npm install
