Can't get ganache going

[Trent McConaghy]

I can't get Ganache going (1) automatically, or (2) running separately. Details:

---

1. Ganache is supposed to auto-start from Brownie, if it isn't run before. The README expects it. Going through the README, I get to the following line:

pytest sol057/contracts/simpletoken/test/test_Simpletoken.py::test_transfer

And it returns

2. I can't get Ganache by running it as its own process. Here's what happens

Even ganache directly dies.

(venv) trentmc@trentmcLnv:~/code/tokenspice$ ganache-cli 
Error: error:0308010C:digital envelope routines::unsupported
...

[Trent McConaghy]

I googled "Error: error:0308010C:digital envelope routines::unsupported"

It turns out that it's a node.js error. Details here

The solution is to downgrade from node.js v17 to v16, using node version manager (nvm):

nvm install 16.13.0

With this, I am now able to run ganache-cli and run tsp ganache (approach 2). However I still have the same error for auto-run (approach 1).

Digging around, I found that I have to also do:

nvm use 16.13.0

Now, it works too!

Final note: this issue was also discovered by eth-brownie community. Details.

Update: even better: use nvm 16.13.2, not 16.13.0.

I am also facing the same issue and it is not working even after using 16.13.0 or 16.13.2

[Trent McConaghy]

I am on a new setup running ubuntu 22.04. I was able to go through the TokenSPICE README out of the box.

Some notes:

• when I installed ganache (via sudo npm install ganache-cli --global) it warned me that ganache-cli is now just ganache. However that didn't seem to pose issues. The warning itself: "npm WARN deprecated ganache-cli@6.12.2: ganache-cli is now ganache; visit https://trfl.io/g7 for details"
• I didn't bother trying to install a different version of nvm. In fact I don't even have nvm on my new setup right now, and there aren't issues.

Do you have more detailed error messages?
