Tried installing challenge-1-decentralized-staking using yarn and then using npm, both failed

Yarn install fails.
Looks like it is the missing content at https://codeload.github.com/hugomrdias/concat-stream/tar.gz/057bc7b5d6d8df26c8cf00a3f151b6721a0a8034

Here are some details:

Tried on node version v18.16.0 and it didn't work. Tried again on node v18.17.1 Still getting https://codeload.github.com/hugomrdias/concat-stream/tar.gz/057bc7b5d6d8df26c8cf00a3f151b6721a0a8034: Request failed \"404 Not Found\ yarn start fails

Take a look to my solution, I did it for challenge-2 branch, but it should also fix this challenge-1 as it is the same issue. I will do another PR for that one as well

The probleme still the same, do we have a solution ?

Hi @ottodevs, for Challenge-0, I tried the changes you made for the dependencies and I was able to install properly the dependencies and then running yarn chain, but when trying yarn deploy I'm getting several errors(guessing that they are maybe related to the openzepellin versions, mine are "@openzeppelin/contracts": "^4.3.3" and "@openzeppelin/contracts-upgradeable": "^4.4.1", ). Did you face any similar problem?

The errors are:

Hi @fremdelve and @Maximesol I just would like to suggest taking a look to this other repo: https://github.com/scaffold-eth/se-2-challenges/, where there is lot of effort put into adapting the challenges to version 2 of scaffold eth, and most of the issues we were discussing here were already fixed.

I solved most of the challenges by just using that other repo instead. This one seems abandoned for some months now.
