Hello my name is Goodness, i’m a computer science student at the university of jos Nigeria
I participated at the aeternity hackerthon conducted in the university of jos.I was introduced to building smart contract with the sophia language
I’ve been playing with the sophia syntax and i’ve encoutered alot of issues:
I can’t install the forgae tool and also the aeternity js sdk(for a node app) which keeps breaking
Hard to connect the browser sdk to our client side application
I need professional support at least a developer on the aeternity team who could help me and is avialable to help me solve this issues.
Here’s the github link to my dacade’s challenge GitHub - GoodnessEzeokafor/Dacade-Challenge: For This challenge i built a decentralized bucketlist app on the Aeternity Blockchain using Sophia
I’m having issues displaying the bucketlists i created on the blockchain on the client side
I want to begin development of a voting app which I want to deploy on the blockchain for Nigerian Universities but this current challenge is slowing me down
hey @Goodness, glad to have you around! As all the components are still very young, your insights will be very valuable to us. Let’s go step by step on multiple routes:
forgae : How did you try t install it and what were the results ?
JS-sdk : How did you try using it, where/in what context (nodejs?), and what were the difficulties ?
Thanks for the reply

hey @martingrigorov.chain, doesn’t this or other parts of the error above sound like one needs to have some of microsoft’s .NET distributables installed or whatever? I work with mac and linux so no clue about this, do you maybe know ? If it’s any of that stuff, could you maybe add it as a side node in the forgae installation steps in your github readme and gitbook doc ?
Same thing for the SDK I think, maybe @shekhar-shubhendu knows ?

@Goodness could you try installing Microsoft .NET Framework 4.7.2 Offline-Installer für Windows - Microsoft-Support and give it one more try ?
It seems to be an issue on your local machine. I’ve never tried running all this on windows. Can you tell us your system configuration, that might help debugging it.
I think we have saw an issue like this. The issue is with the argon library as far as I remember. The version of python that you use is probably 3.7? Can you try to downgrade the python version, to 2.7.* ?
We will keep investigating this.
Best,
Martin
@Goodness as pointed out by @martingrigorov.chain this seems like an issue with the argon2 library and windows. Since i don’t have a windows machine i’m unable to test it out.
can you(or someone with windows machine) please run this provide the results: npm install [email protected]
windows 8.1
npm 6.9.0
node 10.16.0
python2.7
i did and i got an error

i’ve tried that, and i got that error
So i finally installed the sdk and forgae this morning
i had to install visual studio 2017
thanks alot for your help
visual studio 2017 did the trick
@Goodness so probably visual studio 2017 has installed some configurations that help on this… Great!
Is someone around who can help me with running a node on an amazon aws ec2? I think i finally managed to raise ulimit but i think i can not start the node in a way that it is reachable from public (i’ve tried ./bin/aeternity start and then i tried to query the top with the ip of my server but that times out so i guess its not running curl http://18.222.106.194:3013/v2/blocks/top ) - do i have to open the 3013 port somewhere on Amazon to make it possible to query it?
