Issues with truffle

Ethereum Smart Contract Programming 201

I’ve succesfully installed truffle on my laptop but my pc seems to have issues. When I execute the develop command npx truffle develop (the npx is required to find the command). Then I’m met with the following error:

Error: error:0308010C:digital envelope routines::unsupported

Truffle v5.4.19 (core: 5.4.19)
Node v17.1.0

Any ideas on how to handle this?

Hey @Lennart_Lucas, hope you are well.

Could be the Node version that you have, take a look into this quick guide to downgrade NodeJs to at least the version 10 or 12 (im using 12 since quite some time, no issues found so far).

I’m having the same problem, and we are both using version 17…

Ok, I found a workaround by downgrading nodejs to version 12.0.0. Hope this helps anyone else in the same situation.
